@cap-js-community/common@cap-js-community/commonSix independent features for CAP services in one package: replication cache, migration check, rate limiting, a Redis client broker, a local HTML5 repository and a CDM builder.community org, cap
Six CAP features in one package, from replication cache to rate limits
It is a bundle, not a plugin with one job. Depending on it for one feature brings the rest.
@cap-js/attachments@cap-js/attachmentsAn official CAP Node.js plugin for attachment handling, with local database storage and AWS S3, Azure Blob or GCP Object Store integration.sap official, cap
CAP Node.js attachments with database, S3, Azure or GCP storage
@cap-js/cds-dbs@cap-js/cds-dbsThe monorepo behind CAP's SQL database services — the base service, SQLite, PostgreSQL and HANA all live here, which is why they version together.sap official, cap
Monorepo of CAP's SQL database services
@cap-js/db-service@cap-js/db-serviceThe base every CAP database service is built on: the shared query translation and pooling that SQLite, PostgreSQL and HANA specialise rather than reimplement.sap official, cap
Base service shared by CAP's SQLite, PostgreSQL and HANA services
@cap-js/hana@cap-js/hanaThe HANA database service — the production default, on the same streamlined architecture as the SQLite and PostgreSQL services.sap official, cap
SAP HANA database service for CAP
@cap-js/postgres@cap-js/postgresThe PostgreSQL database service — the production option for running CAP off HANA, sharing the base service with the other three.sap official, cap
PostgreSQL database service for CAP
@cap-js/sdm@cap-js/sdmStores attachments in an SAP Document Management repository instead of a bucket, for the case where the documents have to live in the system of record.sap official, cap
CAP attachments stored in an SAP Document Management repository
If document versions are required, [@cap-js/sdm](artifact:cap-js-sdm) excludes versioned repositories in its [documented restrictions](https://raw.githubusercontent.com/cap-js/sdm/ad13b61f21816ebead2d08264a74521cfb75846c/README.md).
@cap-js/sqlite@cap-js/sqliteThe SQLite service, in memory during the inner loop — which is why a CAP project runs before anyone has provisioned a database.sap official, cap
SQLite database service for CAP, in memory during development
@neoimpulse/cap-js-restore-model-defined-types@neoimpulse/cap-js-restore-model-defined-typesA CAP plugin that casts values back to the types the CDS model declares after a READ, for the entities you name, where the database driver returned them as strings.independent, cap
CAP plugin casting read values back to CDS model types
@neoimpulse/cap-js-trim@neoimpulse/cap-js-trimA CAP plugin that strips whitespace from string elements on write, driven by a @cds.trim annotation on an entity or on single elements.independent, cap
CAP plugin stripping whitespace from strings on write via @cds.trim
@neoimpulse/cap-js-uppercase@neoimpulse/cap-js-uppercaseA CAP plugin that uppercases string elements on write, driven by a @cds.uppercase annotation on an entity or on single elements, the twin of the trim plugin.independent, cap
CAP plugin uppercasing strings on write via @cds.uppercase
@sap/cds@sap/cdsThe CAP Node.js runtime, which compiles the CDS model, serves the services declared in it, answers generic requests before any handler runs, and loads every cds-plugin.sap official, cap
CAP Node.js runtime
@sap/cds-common-content@sap/cds-common-contentISO-standard content for CAP's common definitions — countries, languages, currencies and timezones — so a project does not seed those tables itself.sap official, cap
ISO content for CAP's countries, languages, currencies and timezones
@sap/cds-compiler@sap/cds-compilerCompiles CDS models to CSN, EDMX and database schemas.sap official, cap
Compiler from CDS models to CSN, EDMX and database schemas
@sap/cds-dk@sap/cds-dkThe command line client and development toolkit for CAP projects, with the commands cds build, cds deploy, cds watch and cds add among them.sap official, cap
Command line client and development toolkit for CAP
@sap/cds-mtxs@sap/cds-mtxsMultitenancy, tenant provisioning and model extensibility for CAP.sap official, cap
Multitenancy, tenant provisioning and extensibility for CAP
@sap/hdi-deploy@sap/hdi-deployThe Node.js deployer for SAP HANA Deployment Infrastructure: it writes a database module's design-time files into an HDI container as a delta, and it is what cds deploy runs for SAP HANA.sap official, cap
Node.js deployer for SAP HANA Deployment Infrastructure containers
cap-attachments-pluscap-attachments-plusA CAP Node.js attachments plugin with an Attachments aspect and a Fiori elements upload facet, storing content in the database locally or in AWS, Azure or GCP through a BTP destination.independent, cap
CAP Node.js attachments plugin with database or cloud storage
cap-collaborative-draftcap-collaborative-draftA cds-plugin that gives a CAP Node.js service the OData contract, tables and handlers Fiori elements needs for collaborative draft, so a second user joins an open draft instead of meeting HTTP 423.independent, cap
Collaborative draft support for CAP Node.js services
The maintainer marks this under active development; public APIs, annotation names and OData contracts may still change.
cap-postgres-btp-connectivitycap-postgres-btp-connectivityConnects a CAP Node.js application to a PostgreSQL database that is not publicly reachable, tunnelling through BTP Connectivity and the Cloud Connector.independent, cap
Tunnels CAP Node.js to a private PostgreSQL via Cloud Connector
cap-snowflakecap-snowflakeA CAP database adapter for Snowflake with OData V4 support, which the maintainer marks as early development, so its contract is expected to move.independent, cap
CAP database adapter for Snowflake with OData V4 support
The maintainer marks this early development; expect the contract to move.
cap-user-infocap-user-infoResolves the createdBy and modifiedBy of a managed entity to a stored user record of email, given name and family name, and renders the two fields as links with a quickview.independent, cap
User details and quickview links for createdBy and modifiedBy
cds-cachingcds-cachingA caching plugin for CAP covering queries, requests, function results and remote service responses, through a read-through API or @cache annotations, with HCQL and MCP support.independent, cap
CAP caching plugin for query results and remote service responses
When user-dependent responses are cached without user-aware or explicit operation keys, or translated responses share keys across locales. These cases require key isolation; locale-aware keys are off by default.
cds-data-federationcds-data-federationA data federation plugin for SAP CAP applications that declares delegation, caching and replication on a consumption view through CDS annotations, instead of hand-written handlers.independent, cap
Data federation for CAP via delegation, caching and replication
cds-data-pipelinecds-data-pipelineDeclarative scheduled pipelines between CAP services — each one a linear READ, MAP, WRITE from a single source to a single target, with tracking, retry, delta support and a management API.independent, cap
Scheduled READ, MAP, WRITE pipelines between CAP services
cds-federation-synonymscds-federation-synonymsAn experimental CAP plugin for CAP-to-CAP data federation over SAP HANA synonyms, so one project reads another's tables without the rows being copied.sap official, cap
CAP-to-CAP data federation over SAP HANA synonyms
When your adoption policy excludes experimental dependencies: the [maintainer’s README](https://github.com/cap-js/cds-federation-synonyms#about-this-project) explicitly labels this plugin experimental.
cds-numberrange-plugincds-numberrange-pluginA CAP plugin that fills an annotated CDS element with the next number from a named range, optionally with prefix, suffix and padding, keeping the counter in a database entity it adds to the model.independent, cap
Fills a CDS element from a database-backed number range
cds-spreadsheetimporter-plugincds-spreadsheetimporter-pluginA CAP plugin that adds an ImporterService accepting an uploaded Excel file, parses it on the server and writes its rows into the CDS entity named in the URL.community org, cap
Spreadsheet upload into a CDS entity, parsed on the server
com.sap.cds:cds-feature-attachmentscom.sap.cds:cds-feature-attachmentsA CAP Java attachments package that adds an Attachments aspect and stores content in the database by default, or in AWS, Azure or Google Object Store through a separate module.sap official, cap
CAP Java attachments with database storage and an Object Store module
For deployed environments, the [README](https://raw.githubusercontent.com/cap-java/cds-feature-attachments/302f61c8bb76a0f54f43482ad91d89bf7dc5540f/README.md) excludes the cds-feature-attachments-fs file-system target, which is intended only for local development and testing.
com.sap.cds:sdmcom.sap.cds:sdmA CAP Java plugin that stores attachments in an SAP Document Management repository through an Attachments aspect, with draft handling and direct creation on active entities; versioned repositories are excluded.sap official, cap
CAP Java plugin for attachments in SAP Document Management
If document versions are required, the [documented restrictions](https://raw.githubusercontent.com/cap-java/sdm/673769f24ef66fd97daa6a6be41262d45065d3fe/README.md) exclude versioned repositories.

Simple CDS bookshop model used across CAP explanations
Neither the package manifest nor the repository tree declares a licence.
cap-cross-containercap-cross-containerA sample of five CAP services reading each other's HANA tables across HDI containers, with the grantor service key turned into a user-provided service.independent, cap
CAP services reading each other's HANA tables across HDI containers
Neither the package manifest nor the repository tree declares a licence.
capire/bookshopcapire/bookshopThe primer of CAP: a bookshop small enough to read in one sitting, whose Books and Authors every CAP explanation, including this graph's, assumes you have already seen.sap official, cap
CAP's getting-started bookshop sample
capire/bookstorecapire/bookstoreA composite application assembled from separately deployed services — bookshop, reviews, orders and a common content package — rather than one project with more folders in it.sap official, cap
Composite CAP app from separately deployed services
SAP-samples/cap-cds-hands-onSAP-samples/cap-cds-hands-onA hands-on, five-part workshop on CAP's Conceptual Definition Language, from a first entity definition through types, aspects, associations and compositions to annotations and declarative constraints.sap official, cap
Five-part workshop on CDS, from a first service to constraints
SAP-samples/cap-hana-exercises-codejamSAP-samples/cap-hana-exercises-codejamAn eight-exercise CodeJam that builds a full-stack CAP application on SAP HANA Cloud, from HDI containers to calculation views and stored procedures.sap official, cap

@ui5/webcomponents@ui5/webcomponentsSAP's UI elements as standard custom elements, ui5-button among them, implementing SAP Fiori design and usable from plain HTML, React, Angular or Vue.sap official, ui5
SAP's UI elements as standard custom elements
Not where the UI library itself is expected to bind data: the documentation leaves binding a component's content and events to the host framework. Not from a CDN script tag: the project publishes none, so it assumes a build step.
ui5-cc-spreadsheetimporterui5-cc-spreadsheetimporterA UI5 component that adds a spreadsheet upload dialog to a Fiori elements or freestyle app and submits the rows it reads through the app's own OData model.community org, ui5
UI5 component adding a spreadsheet upload dialog to Fiori apps
ABAP Statistical ToolsABAP Statistical ToolsA single ABAP class that computes descriptive statistics over an internal table, with group-by, correlation, histograms and generators for the common probability distributions.independent, abap
ABAP class for descriptive statistics over an internal table
abap2UI5 for Excelabap2UI5 for ExcelAn Office add-in that runs an abap2UI5 app in Excel's task pane, where the app reads and writes the workbook through the z2ui5.cc.ExcelBridge control.community org, abap
Office add-in running an abap2UI5 app in Excel's task pane
abap2UI5-addons/table-content-loaderabap2UI5-addons/table-content-loaderAn abap2UI5 developer tool that moves the content of an ABAP table in and out of JSON, CSV or XLSX files, with a preview before download or saving to the database.independent, abap
Upload, edit and download ABAP table content as JSON, CSV or XLSX
Not an end-user app: it reads from any table the user names and writes into tables of the Z/Y namespace, with no authorisation check of its own, so the README asks a project to add its own checks on `S_TABU_DIS`/`S_TABU_NAM` and to restrict who may run it before it is used beyond a development system. XLSX upload and download are not ready for ABAP Cloud yet, and of the upload apps only the JSON one writes the file's rows back to the database.
abapDataToTableImportabapDataToTableImportAn ABAP framework that declares a target structure in code and maps data a user supplies from a clipboard, an Excel file, a text file or an internal table onto it, with drag-and-drop column mapping.independent, abap
Maps clipboard, Excel or text data onto a declared ABAP structure
boy0korea/abap2jsonboy0korea/abap2jsonA report that exports ABAP table content to a JSON zip file, per table or per package, imports it back into its table, and compares or copies table content across servers.independent, abap
Exports and imports ABAP table content as zipped JSON
boy0korea/ABAP2XLSX_HELPERboy0korea/ABAP2XLSX_HELPERHelper methods over abap2xlsx to download, email or upload a table as Excel, and to convert between Excel, JSON and an ABAP table.independent, abap
Helper methods over abap2xlsx for Excel, JSON and tables
cdsanalysercdsanalyserA search tool that maps SAP database tables and fields to the CDS view entities that expose them, and back, from an index a background job builds, for SAP S/4HANA on-premise or private cloud.independent, abap
Maps database tables and fields to the CDS views exposing them
Not on the [SAP BTP ABAP environment](artifact:btp-abap-environment) or another cloud ABAP system: the maintainer states the tool is not cloud ready, because the data sources and system tables it reads CDS metadata from are not released for cloud development. It is designed for SAP S/4HANA on-premise or private cloud, and the shipped Fiori application is configured for A4H and developer systems.
ERPLERPLA DuckDB extension that reads SAP ERP tables, CDS views and BW queries from SQL over RFC, BICS and ODP, and can mount an SAP system as a DuckDB catalog to join against other data.independent, abap
DuckDB extension reading SAP ERP tables, CDS views and BW queries
DataZoo GmbH calls the extension experimental and states that minimal testing and benchmarking were done. The Business Source License 1.1 it carries restricts offering the software to third parties on a hosted or embedded basis, so an embedding product needs a commercial licence. Telemetry is on by default and is switched off per session with `SET erpl_telemetry_enabled = false` or for the machine with `DATAZOO_DISABLE_TELEMETRY=1`.
lock-managerlock-managerHolds an SAP lock across the HTTP roundtrips of a stateless abap2UI5 app, by making a background job the owner of the kernel lock and a database registry the record of who holds it.community org, abap
Holds SAP locks across stateless abap2UI5 roundtrips
Where the release and programming model offer durable locks, as RAP draft handling does, the README states that those solve the problem at the kernel level and the lock manager is for where that is not an option. A running handler occupies one background work process for as long as any lock is held, and only generated `ENQUEUE_*` modules can be locked.
open-abap-lockopen-abap-lockConcurrent and cross-session locking for open-abap, working only with PostgreSQL as the database backend and only on the DEFAULT connection.community org, abap
Concurrent and cross-session locking for open-abap on PostgreSQL
Neither the package manifest nor the repository tree declares a licence.
open-table-maintenanceopen-table-maintenanceA low-footprint table maintenance in ABAP, served over HTTP for one table whose name is fixed in the code, running on-premise, in "Steampunk", on open-abap and on Cloud Foundry.community org, abap
Table maintenance over HTTP for a table fixed in code
Not for a table whose contents matter, and not for one chosen at run time: the name of the table is fixed in the calling code, and the maintainer's own warning is "only hardcode the table name, don't use with important tables, use at own risk!"
table-maintenancetable-maintenanceA browser-based table maintenance UI, built on abap2UI5, for editing custom and customising table entries with no Eclipse or SAP GUI install.independent, abap
Browser-based table maintenance UI built on abap2UI5
The app writes to whatever table is passed in the URL parameter `table` and carries no authorisation check of its own, so past a development system it needs authorisation checks added and a restriction on who may run it.
ZABAP_TABLE_EDITZABAP_TABLE_EDITA generic ABAP transaction that edits any table's rows and writes its own change documents, without generating an SM30 maintenance dialog, and is extended per table through an interface.independent, abap
Generic ABAP table editor writing its own change documents
abap-file-uploaderabap-file-uploaderSample code that uploads a JSON file whose attributes match a table's column names into that ABAP table on an SAP BTP ABAP Environment instance, through a handler class on an HTTP service.sap official, abap

Neither the package manifest nor the repository tree declares a licence.
SAP-samples/abap-alv-google-upload-sheetSAP-samples/abap-alv-google-upload-sheetSample code that exports SAP GUI ALV grid data directly to Google Drive, where it appears in Google Sheets, with the OAuth, endpoint and ALV configuration around it described in SAP's own guide.sap official, abap
Sample exporting SAP GUI ALV grid data to Google Drive
Not where SAP's own Google Workspace integration already applies: the README opens by announcing a native integration between Google Workspace and [SAP S/4HANA](external:sap-s4hana), whose first set of features is included in SAP S/4HANA Cloud 2208 and SAP S/4HANA 2022 and needs an additional licence for the SAP Document Management Service. Not where end users cannot each hold a regular Google account, since there is no way to use an enterprise account or to log on to Google Drive through single sign-on, and not where the redirect URL Google calls cannot reach a public top-level domain server. No SAP standard support is provided for it.

@mariodefe/sap-datasphere-mcp@mariodefe/sap-datasphere-mcpForty-five tools across a Datasphere tenant — discovery, metadata, analytics, ETL extraction, database users, lineage and column profiling — with config-driven PII masking applied before anything reaches the model.independent, btp
MCP server with forty-five tools across a Datasphere tenant
It writes and it administers — ETL extraction and database user management are not read operations, and the same connection that profiles a column can move data out of the tenant. Masking is only as good as the configuration naming the fields, so an unlisted sensitive column is an unmasked one.
@sap/hana-client@sap/hana-clientSAP's own Node.js driver for SAP HANA: connect, run SQL and prepared statements, synchronously, through callbacks or as promises, over native client libraries npm installs per platform.sap official, btp

bw-modeling-mcpbw-modeling-mcpReads, creates and modifies BW/4HANA modelling objects through the same internal APIs Eclipse BWMT and the BW/4HANA Cockpit use — and can run centrally on BTP with each caller reaching BW as themselves.independent, btp
MCP server for BW/4HANA modelling objects
Its README says it plainly and so does this entry: this is not a simulation, every tool call reaches a live BW system, and write operations produce real changes. BW modelling objects are the definition of a warehouse — the blast radius of a wrong one is every report built on it.
dbt-sap-hana-clouddbt-sap-hana-cloudA dbt adapter, installed as a Python package beside dbt-core, that lets a dbt project target SAP HANA Cloud as its warehouse through a profile in profiles.yml.sap official, btp

hdbhdbSAP's HANA driver for Node.js, written entirely in JavaScript so installing it pulls in no native client, running SQL against SAP HANA and SAP HANA Cloud with streams and prepared statements.sap official, btp
Pure JavaScript SAP HANA driver for Node.js
Its own feature comparison marks connection pooling, automatic reconnect, active-active reads, client-side data encryption, statement distribution, Kerberos authentication, the hdbuserstore, promises and TypeScript types as [@sap/hana-client](https://www.npmjs.com/package/@sap/hana-client) only, so a service that wants a pool or a promise API writes both itself over a callback interface. OpenSSL is its one security provider where the other driver lists SAP CommonCryptoLib, OpenSSL and MSCrypto, and it runs on Node.js 18 or later.
mcp-sap-datasphere-servermcp-sap-datasphere-serverThe read-only Datasphere server: explore spaces, list assets, preview rows, profile columns and summarise analytical models — and nothing that changes anything, by design.independent, btp
Read-only MCP server for exploring SAP Datasphere
Business Source License 1.1, which is source-available rather than open source: reading and evaluating are fine, and production use is restricted until the licence's change date. That is a procurement question, not a technical one, and it is the thing to settle first. Read-only also means read-only — no modelling, no loads.
SAP Datasphere Plugin for ClaudeSAP Datasphere Plugin for ClaudeEighteen Datasphere skills over a bundled 45-tool MCP server — exploration, view and analytic-model design, BW Bridge migration, security architecture and catalog governance.independent, btp
Eighteen Datasphere skills over a bundled MCP server
It reaches a data warehouse, so what an agent can see is business data by definition — the SQL sanitisation and PII filtering in the server are there because of that, not instead of a decision about it. And the guidance is Datasphere-shaped: nothing here transfers to a HANA Cloud database used directly.
sap-bdc-mcpsap-bdc-mcpDiscovery and contract tooling for SAP Business Data Cloud — ORD discovery, CSN contract checks and non-executing share planning — behind redaction, policy gates and bounded output.independent, btp
MCP tooling for SAP Business Data Cloud discovery and contracts
Business Source License 1.1: source-available, with production use restricted until the change date — settle that before anything technical. And the governed execution path in v0.2 does act on data, which is a different grant from the discovery the v0.1 baseline offered.

🔴 Your Agent Wants to Call SAP. Now What?🔴 Your Agent Wants to Call SAP. Now What?Devtoberfest 2026 session INT-23, on what belongs between an agent and an SAP system. A solution advisor and an enterprise architect point Joule Desktop extensions at MCP servers built on API Management inside SAP Integration Suite, and ask it for business partners, orders and line items from an S/4HANA demo system; asked for the ten largest customers it answers from a sample of 200 orders rather than reading the whole table. They then open the API proxy behind it, where a spike arrest policy caps the backend at ten calls per second and the MCP server is configured to expose only the GET resources of the business-partner API so that an agent cannot create one, which is where the edges to Serve your application over MCP and Rate limiting hold. For totals across all sales orders they send the agent to SAP Business Data Cloud instead of the transactional system, since it aggregates and is read-only, and back through Integration Suite for writes such as journal entries.SAP Developers, published 2026-09-30

ABAP in Practice - Creating a Setup AppABAP in Practice - Creating a Setup AppWalks through an unmanaged custom entity behind a static Fiori Elements setup app: a factory maps step IDs to implementation classes behind one interface, and the transactional model sets every CRUD operation internal while adding CheckStep and ExecuteStep actions instead of generated persistence. It buffers the executed step for the save sequence and moves an API that issues a COMMIT to a background process via bgPF, since a COMMIT inside the action is forbidden in strict mode.Björn S., published 2026-08-28
Always in Sync — Field-level and event-driven side effects for reactive UIs in RAPAlways in Sync — Field-level and event-driven side effects for reactive UIs in RAPA Devtoberfest 2026 session on side effects in RAP — the declarations in a behaviour definition that tell a draft UI to reload what a change affected, instead of leaving the user to refresh the browser. Field-level side effects recalculate a total price from a determination when a booking fee is entered, including across the association from a child item up to the root entity, and a permissions side effect toggles a description field between read-only and editable; a global side effect is attached to a determine action, fires when the user presses Enter, and only one may exist per business object, which is why the prepare action and a second determine action cannot both carry it. The last part starts a long-running calculation through the background processing framework and raises a business event that the behaviour definition lists as a side effect source and the projection makes public, so the Fiori app is updated with a notification when the work finishes, whether it was triggered by the user or by an application job — the transactional model and the async processing side the edges rest on.published 2026-10-05
Automate Recurring Data Updates in SAP HANA CloudAutomate Recurring Data Updates in SAP HANA CloudA walkthrough for marking inventory rows stale after 30 days using SAP HANA Cloud's own scheduler: a SQLScript procedure, a CREATE SCHEDULER JOB statement with its 7-field cron pattern, the M_SCHEDULER_JOBS monitoring view, and the matching DROP statements to remove both. It then names where that approach stops and lists the alternatives for scheduling outside the database: SAP Integration Suite's Timer Event, the SAP Job Scheduling service, SAP Automation Pilot for infrastructure commands, and a custom approach for triggering scheduled REST calls from an application.Joni, published 2026-06-11
Beyond READ_TEXT: Decoding SAPscript Long Texts (STXL) with SQLScript in CDS/AMDPBeyond READ_TEXT: Decoding SAPscript Long Texts (STXL) with SQLScript in CDS/AMDPSTXL stores a SAPscript long text as a compressed ABAP cluster container — LZ77 plus canonical Huffman — so the only official reads are READ_TEXT, one call per text, and its mass variant READ_TEXT_TABLE, both of which ship every decompressed line to the application server and stay invisible to ABAP CDS. The author reverse-engineered that on-disk format and ported the decoder into SQLScript, wrapped in an AMDP procedure and exposed through CDS table functions, turning long texts into a joinable, filterable column read directly in the database. On ABAP 7.56 a table function needs the driver-and-filter pattern shown because a parameter cannot bind to a calling column; on ABAP 7.58/S/4HANA 2023 the same result becomes a parameter-less CDS scalar function with true filter push-down.aamelin1, published 2026-08-20
Bridging Python and SAP HANA: Inside the sqlalchemy-hana Open-Source DialectBridging Python and SAP HANA: Inside the sqlalchemy-hana Open-Source DialectA Devtoberfest 2026 data-track session (DAT-21) in which one of the maintainers of sqlalchemy-hana, the open-source SQLAlchemy dialect published in SAP's GitHub organisation, opens up what sits between Python and SAP HANA. It walks the five dialect classes that render statements, types, DDL, identifiers and sequences, and the HANA specifics they absorb: the FROM DUMMY a bare SELECT needs, a limit injected when only an offset is given, string compiled to NVARCHAR, and quoted case-sensitive identifiers against Python's lowercase. The rest covers schema migrations with Alembic on HANA's transactional DDL, the recently added async support and vector types, and that HANA Cloud and HANA 2 are supported while HANA 1 is not.SAP Developers, published 2026-09-29
Bring "developers.sap.com" Into Your Dev Environment: SAP Developer Context for AI Coding AgentsBring "developers.sap.com" Into Your Dev Environment: SAP Developer Context for AI Coding AgentsDevtoberfest 2026 session FA-11: a tour of the rebuilt developers.sap.com by the team that runs it, from the administration screens behind the home page to the agent interfaces in front of it. The site is a CAP application on SAP HANA Cloud and SAP BTP, open-sourced in full, and the half of the session that places it here is how its content reaches an agent: every tutorial is also served as markdown, a coding agent is detected and given that version instead of the HTML, a well-known agent card advertises what the site offers, and SAP Developers MCP answers questions about tutorials, news and a reader's own completion history in Claude Code and Joule Desktop, over OAuth or a personal access token. Behind the answers sit two things working together: a knowledge graph in the HANA database over 1400 tutorials and 11,000 concepts, and SAP AI Core for the Joule interactions and the embeddings, with the agent harness written for the site rather than taken off a shelf. Where neither MCP nor A2A is available, the same content is published as skills.SAP Developers, published 2026-09-25
Building an SAP BTP Agent Architecture from Scratch: Python + CAP + HANABuilding an SAP BTP Agent Architecture from Scratch: Python + CAP + HANAA first-person build log of a Flask orchestrator on Cloud Foundry that reduces a question to keywords, searches a Node.js service's Documents entity, and passes what it finds to Claude for a grounded answer. Getting there means learning that HANA's fuzzy .search() matches one word but not a full sentence, fixed by splitting the query into terms and merging the per-term hits, and that provisioning SAP HANA Cloud hits a database-level free-tier quota rather than an HDI-container one, with a stopped instance needing to be resumed first. It also covers @sap/cds-dk needing to sit in dependencies rather than devDependencies, since Cloud Foundry's buildpack skips the latter, before cds deploy --to hana can run as part of the push.neilaspin, published 2026-07-28
Building your knowledge graph on SAP HANA CloudBuilding your knowledge graph on SAP HANA CloudDevtoberfest 2026 session DAT-11, in which two enterprise architects explain what a knowledge graph is and then build one on SAP HANA Cloud. The first half sets the join across three relational tables against an ontology of classes and predicates, the subject-predicate-object triple written as a turtle file, and a SPARQL query over it, and argues that the chain of relationships is what makes a recommendation traceable back to its reasons. The demo, taken from a Discovery Center mission, curates the ontology and the RDF files for an accounts receivable scenario in VS Code, ingests the triples into HANA Cloud with SQL and walks the resulting graph outward from a customer; that is the graph, spatial and document data edge. It closes by separating three things that share the name: the HANA Cloud knowledge graph engine, SAP Knowledge Graph as the data, and the knowledge graph in SAP Business Data Cloud.SAP Developers, published 2026-09-22
CAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry is a prototype that generates a CAP Node.js project with SAP Fiori elements from a written business requirement, discovering the actual data shape from a chosen source — SQLite, a configured SAP HANA HDI container, offline EDMX, live OData through the SAP Destination service, or approved SAP BTP ABAP objects — instead of inventing one. The generated application can carry a Fiori draft lifecycle with optimistic concurrency via ETags and annotation-driven Fiori elements list and object screens, localized independently of the underlying service contract. Attachments can be added with upload, download and delete, gated on a malware-scan status, and the generated project still has to compile, build and pass its generated tests before the run is accepted.Shahid, published 2026-08-20
CAP in the age of AI #6 - vector embeddingsCAP in the age of AI #6 - vector embeddingsVector embeddings put to work in the incident management sample, answering whether this problem has been seen before. An embedding element of type Vector is calculated and stored from the vector_embedding function, so the database refreshes it whenever the text behind it changes, and cosine_similarity compares it with a freshly embedded string; because a title says little, a scheduled action first summarises each incident's conversation through a model on SAP AI Core and the embedding is taken from that summary. The similar-incidents list is a view joining incidents to themselves, with order and limit set in a before handler on the expanded query, and the vector element excluded from the service, since OData knows nothing about vectors — on SAP HANA Cloud the function is native, while SQLite needs packages added to the project.published 2026-10-09
CAP in the age of AI #7 - vector embeddings wrap-upCAP in the age of AI #7 - vector embeddings wrap-upThe same embeddings model taken from SQLite to SAP HANA Cloud, then handed to an agent. Locally it is @cap-js/ai that adds the vector functions SQLite lacks and downloads an all-MiniLM L6v2 ONNX model on first start; on HANA natural language processing has to be switched on, the model name is a mandatory argument, the vectors it returns are 768 dimensions, and dimensions must match on both sides of a comparison. HANA itself can be given SAP AI Core as a remote source for other embedding models, which a CDS.ql expression has to inject because the postfix notation only takes what the CDS model holds, and the hour ends with a search function over cosine similarity exposed over @cap-js/mcp, so an agent asked about low output from solar panels calls semantic search instead of writing the query itself.published 2026-10-16
CAP-level Data FederationCAP-level Data FederationA Devtoberfest 2026 session (CAP-31) on letting one CAP application read another's data as if it were local. The modelling half is the same for both answers, which is why the two technical edges hold: the provider defines an API service and exports it with CDS export as an npm package carrying the model, mock data and translated texts, the consumer imports it and puts consumption views on top, and only then is it wired either as service-level replication that copies the rows into local tables each time the server starts, or over the SAP HANA synonyms that cds-federation-synonyms generates, with HDI grants on the provider side and a service replacement that redirects each synonym from its mock table to the provider's container. It is worked through on xflights and xtravels, including the local run where CDS watch mocks the imported service from the CSV files inside the package.SAP Developers, published 2026-10-02
CDS Associations & JoinsCDS Associations & JoinsA Devtoberfest 2026 session from SAP's performance and scalability team on what an ABAP CDS association becomes on SAP HANA, taken as an excerpt from their internal performance training. The CDS edge rests on the three ways an association is used: a path expression and an explicit join both put a left outer join into the generated view, while exposing the association leaves the view without one and adds the join only for a query that asks for its fields, which the session calls join on demand. The data modelling edge is the advice that follows and the demo under it — cardinality written as precisely as the data allows, because the optimiser trusts it, shown with a view whose missing cardinality let SELECT COUNT(*) prune the join and return 18 rows where selecting the columns returned 56, plus the left-hand, right-hand and left-outer-to-inner rewrites that correct cardinalities make possible.SAP Developers, published 2026-10-12
Combining AI Agents with the power of SAP HANA embedded ML (part 1)Combining AI Agents with the power of SAP HANA embedded ML (part 1)Devtoberfest 2026 session DAT-12, the first of two parts, in which Vitaliy Rudnytskiy does a data scientist's work against the embedded machine learning of SAP HANA Cloud by talking to an agent. The session first takes an agent apart into its LLM, its tools, its memory and the loop between them, then stacks the Predictive Analysis Library under the hana-ml Python wrapper and that under the HANA AI toolkit, whose tools an agent calls from plain English in a notebook to preview a sales refunds table, split it into train and predict tables, run a time-series check and train an AutoML forecast, keeping what it decided in Markdown memory files. That is the agent tooling edge; the same toolkit is then started as an MCP server over stdio and over streamable HTTP and reached from a coding agent and from Joule Work's desktop, which is where the live demo partly fails and the failure is shown.published 2026-09-22

With synonyms in place the consuming project queries the owner's HANA tables through ordinary SQL and ordinary CAP service code, with no replication and nothing to drift between environments.

Developing authorizations for business users in SAP Business AI Platform, ABAP environmentDeveloping authorizations for business users in SAP Business AI Platform, ABAP environmentA Devtoberfest 2026 session that walks the places an authorization check has to be written when a RAP business object is implemented, which is the whole of the authorization edge: read restrictions as DCL access controls that become a filter at query time, a child entity inheriting its parent's conditions through an association, the projection layer inheriting rather than changing them, and the same check repeated on the draft side. The ABAP CDS edge holds on that draft half — until 2608 a draft query view was needed above the draft table so a DCL had something to attach to, while a draft table entity is already on CDS level and takes the DCL directly, as long as the associations used in the inherited conditions are redefined on it. Create, update and delete are then taken handler by handler, including the trap that instance authorization reads the buffer and so cannot see the new value a pre-check would reject, and the session closes on in local mode and privileged EML calls.published 2026-10-12

From SEGW and Legacy UI5 to RAP with ARC-1From SEGW and Legacy UI5 to RAP with ARC-1Three ARC-1 skills, run in Cursor with Composer-2 against a deliberately rough demo on an S/4HANA 2023 trial system, turn the SEGW service ZDEMO_MIG_PROJECTS_SRV into a managed, draft-enabled RAP business object published as OData V4, replace its ApproveProject function import and its direct UPDATE ... COMMIT WORK with the action approve_project written in EML in local mode, and rebuild the freestyle UI5 JavaScript app once in UI5 TypeScript and once as a Fiori elements list report and object page driven by metadata extensions. What the published transcripts add is how the agent got there: it found the generated MPC class names and the custom logic in DPC_EXT only by reading the system, the skills made it print the extracted model and stop for confirmation before writing, and @ui5/mcp-server, mcp-sap-docs and @sap-ux/fiori-mcp-server each had their own job beside it. The demo is small on purpose, and the post says a productive SEGW service that calls BAPIs, carries custom authorisation logic or supports deep inserts is not solved with one prompt.published 2026-05-11

Mastering Internal Actions in SAP RAP: Automatic Header Calculation in ABAP CloudMastering Internal Actions in SAP RAP: Automatic Header Calculation in ABAP CloudWalks through a sales-order BDEF where an item-level determination triggers a header-only internal action by EML in local mode, so a quantity or price change recalculates the order total and applies a 10% discount above $10,000 without a UI button or external OData call reaching the logic directly. Argues for an internal action over inline determination code on reusability and separation of concerns: a determination decides when logic runs, the action decides what runs, and marking it internal keeps Fiori Elements and external OData clients from invoking it.sharathtm, published 2026-08-06
RAP - Native File UploadRAP - Native File UploadA workaround for uploading a file into a RAP application ahead of SAP's own upload and download solution, which is still pending: two abstract root entities — one holding the file's bytes, MIME type and filename, one for a popup dialog — joined by an association flagged with hierarchy, exposed through a static action declared with DEEP PARAMETER so the nested structure reaches the handler. The trade-offs are stated plainly: the popup takes no default values, only one file uploads at a time, and the UI annotation on the attachment field is ignored because its label is read from the sub-entity's own name.Björn S., published 2026-08-18

The live demo asks Joule for the available data products and the top ten open purchase orders, with the data product query agent compiling SQL over virtual tables and a space rendering a dashboard, which is the cataloguing side of this: a central registry, the Unified Customer Landscape, that every activated data product is registered in.

Updates on Embedded Analytics in ABAP Cloud for DevelopersUpdates on Embedded Analytics in ABAP Cloud for DevelopersA Devtoberfest 2026 session (ABA-33) on the generator wizards for Embedded Analytics in ABAP Cloud, run by right-clicking a data definition in the ADT Project Explorer. It first names the artefacts a star schema needs, all of them ABAP CDS — cube view at its centre, dimension, text and hierarchy views reached by association, a hierarchy directory, and an InA service definition and binding — and then generates them: the star schema generator reads a view entity's metadata, sorts its fields into dimensions and measures, asks about the ones it cannot decide, offers the dimension views it found and writes an activated cube view; the hierarchy generator produces directory, node, base and definition views plus a maintenance business object with a generated app, which is used to group airlines into alliances before the hierarchy is switched on in the layout of the multi-dimensional analysis app. That is analytic modelling on the ABAP platform, which is what the edges rest on; the outlook names time-dependent hierarchies, translatable texts and dimensions generated from database tables.published 2026-10-05
What's new with draft handling in RAP?What's new with draft handling in RAP?An ABAP-day session at Devtoberfest 2026 on two additions to draft handling in RAP: collaborative draft, where two users work on the same draft instance and a field is locked only while the other is in it, and draft scope, where editing an instance of one draft-enabled business object puts the related instances of a dependent one into draft as well. Andre Fischer shows what each costs in the behaviour definition and projection, the draft query view and its DCL that collaborative draft needs over a table-based business object, and the CDS table entities that remove both the draft query view and the persistence table, with their current restrictions in ABAP analytics and extensibility; the from-scratch generator in ADT grows a checkbox for them. Both demos run against the DMO flight scenario of SAP-samples/abap-platform-refscen-flight, and the last part hides the draft-related features of an OData V4 app in its manifest, which the session gives as the reason a simple create-update-delete app no longer needs a V2 service binding.published 2026-09-21
