A Guide to CDS Metadata Extensions, Fiori App Generation and SAP UI5 Controller ExtensionsA Guide to CDS Metadata Extensions, Fiori App Generation and SAP UI5 Controller ExtensionsWalks through a RAP-based Fiori elements app end to end: layering UI annotations onto a CDS view through a separate ABAP metadata extension object, gated by @Metadata.allowExtensions on the base view and ordered across extensions by a required @Metadata.layer value. Generates the app in SAP Business Application Studio from the published OData V4 service's merged $metadata document, then adds an SAP UI5 controller extension — registered in manifest.json against a Fiori elements lifecycle hook — only for behaviour the annotations cannot express.ankitapaul229, published 2026-07-27
A Handy Custom Report to Scan SAP CDS Views for Usage of Search StringsA Handy Custom Report to Scan SAP CDS Views for Usage of Search StringsA custom SE38 report, ZSCAN_CDS_VIEWS, reads each Z-prefixed CDS view's DDL source through the function module /ABEX/SEFW_MOD_CVA_HANA and scans it for a list of search strings, listing the view and matching code line in an ALV grid. The author built it because ABAP Development Tools for Eclipse's ABAP Source Search, the code search SAP ships, is unwieldy for scanning many custom views at once or searching several strings together.shasankgupta024, published 2026-01-08
A method to create an Adobe form attachment for a work item using the class concept.A method to create an Adobe form attachment for a work item using the class concept.Walks through an ABAP workflow class, ZCL_WF_PDF, whose methods call an Adobe form through a Form-Builder-generated function module, convert the returned PDF between hexadecimal string and binary with SCMS_XSTRING_TO_BINARY and SCMS_BINARY_TO_XSTRING, and attach it to a work item via SAP_WAPI_ATTACHMENT_ADD and SAP_WAPI_WRITE_CONTAINER, with the class, background-task and SWDD workflow steps shown in full. It explains document output's ABAP route, rendering a PDF through the Form Builder and getting it back into the program, and a route into attachments's ABAP side distinct from Generic Object Services: a file attached to an SAP Business Workflow work item instead.Mithun_Sharma1, published 2026-08-21

ABAP + MCP: Let AI Do Real Development in Your SAP SystemABAP + MCP: Let AI Do Real Development in Your SAP Systemabap-adt-mcp is an open-source MCP server that gives an AI agent full ABAP development capability over ADT: it searches, reads, edits, activates and unit-tests objects, and runs ATC checks, on a connected S/4HANA Cloud or on-premise system, acting as the signed-in developer. It runs on abap-adt-api, the same REST client Eclipse's own ADT tooling uses, and sits beside SAP's own ADT MCP Server, shipped with ADT for VS Code and Eclipse under a different server key, and marianfoo's abap-docs, a read-only server over the ABAP Keyword Documentation and Clean ABAP. Each destination carries a policy — read-only, allowed packages, denied tables and tools — the server checks before every call, and an optional audit file logs each tool call with its outcome and policy gate.Willian_Saez, published 2026-09-03
ABAP Cloud LoggerABAP Cloud LoggerWraps ABAP Cloud's cl_bali_* Application Log classes in ZCL_CLOUD_LOGGER, an open-source, MIT-licensed logger installed via abapGit. One fluent entry point takes free text, sy-msg-style messages, exceptions, BAPIRET2 tables or arbitrary data serialised to JSON, and multiton instances keyed on object/subobject/external number let unrelated code share a logger without passing instances around. It adds sticky per-iteration context, built-in timing, and a readable trail of the cx_bali_runtime errors the class swallows internally.Greltel, published 2026-04-30
ABAP development tools for Visual Studio Code is now available on the VS Code marketplace!ABAP development tools for Visual Studio Code is now available on the VS Code marketplace!Announces the marketplace release of ABAP development tools for Visual Studio Code, an extension that works against any ABAP system already reachable from ADT for Eclipse and is focused on RAP UI service development, so the Fiori/SAPUI5 frontend and the ABAP backend can be built in the same tool. It ships a built-in ADT MCP Server, disabled by default and switched on from the extension settings, and points readers to a documentation template for capturing ABAP-specific rules in a project's AGENTS.md file for chat agents such as Microsoft Copilot.thomasalexander_ritter, published 2026-06-01

Both are new instances of what agent access to your code already covers for ABAP — reading and acting on a real system through ADT — reaching now into a transport's changes and a check run rather than only source and objects.thomasalexander_ritter, published 2026-07-21
ABAP development under the Clean Core paradigm: From BAPIs to BO and CDSABAP development under the Clean Core paradigm: From BAPIs to BO and CDSSAP's Level Based Clean Core classification (2025) grades ABAP APIs A through D by cloud readiness, and this piece uses the S/4HANA Cloudification Repository's own count — of 3,847 BAPI function modules for SAP Cloud ERP Private, only 23 are Level A — to show how much Classic API (Level B) code needs to move to RAP business objects instead. A worked Bank Master example matches each BAPI to its EML statement or ABAP CDS SELECT equivalent, and states when that move is actually required: mandatory once on SAP Public Cloud, optional but advisable on Private Cloud/On-Premise as BAPIs stop gaining new fields.published 2026-05-21

Adding Immutable Blockchain Proofs to SAP With CAP - Cardano and OData V4Adding Immutable Blockchain Proofs to SAP With CAP - Cardano and OData V4The write-up behind ODATANO, by its author: how a public blockchain gets reachable from CAP as an ordinary OData V4 service rather than through a bespoke client. The premise it starts from is worth the read on its own — SAP systems are trusted but mutable, which is what an immutable anchor is for — and Cardano is chosen for peer-reviewed research and formal methods rather than for popularity.

Agentic AI on BTP: a Multi‑Agent App with Pydantic AIAgentic AI on BTP: a Multi‑Agent App with Pydantic AISplits a single CAP/TypeScript agent that had grown to juggle five BTP MCP servers behind one bloated tool list into btp-multiagent-app, a Python and Pydantic AI rewrite where the Cloud Foundry and BTP Core MCP servers each get a dedicated specialist agent, with an audit log specialist scaffolded but left disabled, behind an orchestrator whose only tools are delegation calls to those specialists, which is the agent-tooling pattern the piece works through. Each specialist authenticates to its MCP server over Streamable HTTP with OAuth 2.1, and a shared module centralises the SAP AI Core GenAI Hub model setup behind two credential layouts, one for local runs and one for the Cloud Foundry service binding, the LLM integration side of the rewrite. Tool lists per agent drop from well over a hundred to a dozen or two, and routing failures become separable from tool-misuse failures by reading the trace.published 2026-05-03
Agentic AI on BTP: a Single Agent with LangGraphAgentic AI on BTP: a Single Agent with LangGraphA CAP TypeScript agent puts a LangGraph StateGraph in front of AzureOpenAiChatClient from @sap-ai-sdk/langchain, reaching SAP AI Core's Generative AI Hub, and lets its tool-calling loop draw on five deployed MCP servers — OData MCP Proxy, CI MCP Server, AI Core MCP Server, BTP MCP Server and BTP CF MCP Server — through @langchain/mcp-adapters' MultiServerMCPClient. Because agent, servers and APIs share one XSUAA tenant, the chat service forwards the signed-in user's own JWT instead of a service account, so each downstream server enforces that user's own authorizations. Past roughly a hundred combined tools the single prompt slows down and stops separating concerns, which is why the author's next post splits it into one specialist agent per MCP server behind an orchestrator.published 2026-05-03
API Composition: Seamless Enterprise Data Access for Developers and AI AgentsAPI Composition: Seamless Enterprise Data Access for Developers and AI AgentsAPI Composition (formerly Graph, a capability of API Management) curates business data graphs from existing SAP and non-SAP API providers, so a query can navigate and expand relationships across systems through one composed API rather than hand-written integration code. Palak walks through combining SAP S/4HANA warehouse-stock data with Everstream Analytics risk data into one API, then exposing that composed API as an MCP server so an AI agent calls it with the same semantic context — the scenario behind API Management's MCP servers coverage.published 2026-07-27

Autonomous Diagnostics on Kyma Unplugged: Goose + LiteLLM + KRO + SAP AI Core in ProductionAutonomous Diagnostics on Kyma Unplugged: Goose + LiteLLM + KRO + SAP AI Core in ProductionAn in-cluster autonomous diagnostic pipeline on Kyma Unplugged (open-source Kyma, noted to also run on SAP BTP, Kyma runtime): a Goose agent with kubectl access calls SAP AI Core through a LiteLLM proxy, and most of the post is about the quirks of that route — drop_params silently swallowing unrecognised parameters and beta headers, streaming that has to be off when tools are attached, and prompt caching that sits on the Orchestration V2 API rather than the foundation-model path the LiteLLM provider hits. A second Node.js proxy reaches that API, and the author reports caching unconfirmed at production scale, which leaves the roughly $0.004 per static run a target rather than a measured figure. Spend metrics reach SAP Cloud Logging over OTLP through Kyma's Telemetry MetricPipeline while the health analysis itself lands in Kubernetes custom resources read in Busola, and the stack is declared as KRO Resource Group Definitions applied with one Terraform command.quovadis, published 2026-07-09

Beyond Basic AI Error Handling in SAP CPI - A Rules-First Architecture with HANA Cloud LearningBeyond Basic AI Error Handling in SAP CPI - A Rules-First Architecture with HANA Cloud LearningBuilds a rules-first error-diagnosis pipeline on Cloud Integration in SAP Integration Suite: a Groovy classifier resolves known failures — auth, timeout, malformed payload — deterministically, and only genuinely novel errors reach an LLM through the AI Adapter, after a sanitizer script replaces every payload leaf value with a typed placeholder before it leaves the tenant. SAP HANA Cloud, reached over JDBC, holds a fingerprinted dedup cache and an accumulating table of past diagnoses. It also documents the AI Adapter configuration — Advanced mode, a Bearer-prefixed Secure Parameter, and a connection/processing URL split — needed to reach a non-SAP OpenAI-compatible endpoint, found by the author to be undocumented.Krishna_Karthik, 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

Treating an agent as a software architecture rather than a model with tools makes a list of production requirements — identity, authn and authz, multitenancy, persistence, event-driven flows, scalability, observability, CI/CD — and the author's point is that CAP already answers most of them for BTP, which is what makes LangGraph inside CAP Node.js worth doing.

Building MCP Servers with SAP Integration Suite: What to Design, Not Just How to ConnectBuilding MCP Servers with SAP Integration Suite: What to Design, Not Just How to ConnectArgues that the tool design, not the connection, is the hard part of putting an API in front of an agent. Works one request — create a customer — through eight endpoint-shaped tools, where the agent carries ids between calls and rebuilds the business rules each run, then through a single intent-shaped create_customer that hides the sequence; and says what separates the two: a business operation for a name, parameters a caller can supply without a lookup, the rules in the server rather than the prompt, and a description written for an agent choosing a tool. The SAP Integration Suite half is short — three creation paths, an iFlow behind the API artifact when a tool has to cross systems — and it closes on a checklist to run before publishing.published 2026-07-07

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

Capturing Background Job Errors in SAP Using the Application Log (SLG0/SLG1)Capturing Background Job Errors in SAP Using the Application Log (SLG0/SLG1)Walks through ABAP's Application Log framework for recording errors from a background job that has no screen to show them on: defining an Object and Sub-object in SLG0, then building the log in code with BAL_LOG_CREATE, adding a free-text or message-class entry with BAL_LOG_MSG_ADD_FREE_TEXT or BAL_LOG_MSG_ADD, and persisting it with BAL_DB_SAVE so it survives after the job finishes. The worked example is a report inserting student records into a custom table, scheduled via SM36 and reviewed afterwards in SLG1, filtered by the Object and Sub-object that created it.bhuvaneswarg, published 2026-08-26

Centralized Error Handling in SAP Cloud IntegrationCentralized Error Handling in SAP Cloud IntegrationBusiness integration flows in Cloud Integration route their runtime errors to a shared Central Error Logger flow through an Exception Subprocess and a ProcessDirect adapter, instead of each flow handling failures on its own. The logger normalises the incoming error data — flow name, message ID, correlation ID, timestamps — and formats it into an HTML email sent through a Mail Receiver Adapter. The author validated the same logger flow, unchanged, against a second, more complex business flow with routers and multiple email notifications.vishaladhikari, published 2026-03-27
Claude Code via MCP: Poor man's Joule, or a practical tool?Claude Code via MCP: Poor man's Joule, or a practical tool?The author drives Claude Code against a live ABAP system through vibing-steampunk, an ADT-to-MCP bridge that locks and unlocks objects on the agent's behalf so the model can concentrate on the change: extending an ALV report, turning its SELECT into a CDS view, and answering ad-hoc questions over the report's own data. Where Claude got it wrong — a RAP scaffold missing the fields RAP's locking mechanism needs, ORDER as a reserved word — the piece asks where that knowledge would go as a Skill, and concludes Skills' filesystem basis has no home in a system reached only through MCP.k1000, published 2026-03-08

Event Mesh + AMQP: The Retry Trap Nobody Warns You AboutEvent Mesh + AMQP: The Retry Trap Nobody Warns You AboutWorks through two patterns for retrying failed messages from Event Mesh's AMQP sender adapter on Cloud Integration, whose native retry has no configurable delay or backoff: bridging into a JMS queue for full exponential-backoff control, or looping messages through a dedicated retry queue with a TTL and a Dead Message Queue. Compares both against a Groovy sleep() workaround that blocks the adapter's connection and the runtime's worker thread, and shows that Advanced Event Mesh's own adapter ships configurable retry interval, backoff and broker-side redelivery without either workaround.MateuszPiotrowski, published 2026-03-09

It is the rule-file half of agent guidance rather than the skill half — nothing is packaged or published, and the value on offer is the shape of the split.radu_simen, published 2026-02-05
Governance at Scale: Why a Clean Core Is What Makes Agent Governance EnforceableGovernance at Scale: Why a Clean Core Is What Makes Agent Governance EnforceableClosing a six-part clean-core series, the post argues that SAP's two agentic-AI governance mechanisms only work against a documented tool surface: MCP Gateway in SAP Integration Suite auto-translates API specifications into MCP tool schemas augmented with natural-language semantics, carrying forward existing authentication, authorization and rate limiting into the agentic layer, while AI Agent Hub, built on SAP LeanIX, discovers and runs verification assessments on agents, LLMs and MCP servers before the resulting badge is read by Joule Studio or SAP Integration Suite to decide what is trusted. Its argument holds the mechanisms up against an undocumented internal interface, where the auto-generated schema and the verification badge have nothing real underneath them, and against a consolidated CAP service exposing only released APIs, where both do.DEEPA_DORAIRAJ, published 2026-09-21

How to Implement SAP Change DocumentHow to Implement SAP Change DocumentBuilds SAP's Change Document framework on two custom tables, ZZCUSTOMER and ZZCUSTOMER_BANK: creating the Change Document Object in transaction SCDO, then wrapping each INSERT, MODIFY and DELETE on the Z-tables together with a call to the generated WRITE method inside one ABAP class, so both commit in the same Logical Unit of Work. Because the generated method cannot read old values back from the database itself, the class reads them before the update and holds them in memory; a Managed RAP application skips this step by specifying the Change Document Object directly in its Behaviour Definition instead. This is the ABAP side of change tracking: a change document object logs who changed a field, and when, into CDHDR and CDPOS.Subhasree1, published 2026-07-09
How to rename an OData V4 service?How to rename an OData V4 service?Renaming an OData V4 service binding changes its Service Alias and the resulting service URL, breaking any app already deployed against the old one — shown on a /DMO/TRAVEL-based example in the SAP BTP ABAP environment by unpublishing, renaming and republishing the binding, then reading the new URL back from the OData V4 service catalog's ServiceGroups entry. It weighs that against two alternatives: adding a second service definition and publishing it as a new service version under the same binding, or creating an entirely new service definition and binding, which keeps the original URL live during the cutover.published 2026-07-04

MCP Servers are the New Z-TablesMCP Servers are the New Z-TablesA single CAP service exposed as three overlapping MCP servers tools, queried by the same prompt nineteen times, returned the same tool every time — evidence, the author argues, that tool selection rests on the resemblance between a prompt and a tool's description rather than on any binding a where-used list could enumerate before retiring it. It contrasts that setup with @cap-js/mcp, which exposes a whole service as three generic tools instead of one per operation, and quotes the adapter's own beta documentation admitting no rate limiting, audit logging, input validation or approval workflow, and no use as a gateway to SAP Application APIs. From there it names four small Tool governance practices it has adopted: an owner recorded in the tool's own metadata, logging every invocation, deprecating inside the description, and exposing fewer tools.published 2026-08-21

Named-User Attribution Across BTP Subaccounts: A Two-Hop IAS Token Exchange for Cloud IntegrationNamed-User Attribution Across BTP Subaccounts: A Two-Hop IAS Token Exchange for Cloud IntegrationA central BTP application that manages Cloud Integration across subaccounts with client_credentials collapses every user into one technical service principal: target subaccounts' role collections are bypassed and the audit log names a service key instead of a person. The post works through a two-hop exchange — an IAS app-to-app hop, then the target subaccount's XSUAA jwt-bearer hop — that carries the calling user's own identity across the subaccount boundary through a shared Cloud Identity Services tenant, so the target subaccount enforces the user's own role collection and records their identity in the audit log. It walks through the IAS app-dependency setup, the AppRouter and SAP Destination service configuration the exchange needs, and states the pattern applies to any XSUAA-protected service in a separate subaccount, not only Cloud Integration.agnissh, published 2026-08-24

The edge to POD plugins holds on what it states about plugins themselves: the large monolithic plugins of the old framework have been broken into smaller, focused components, and layout, dialogs, buttons and actions that previously required UI extensions or custom plugins are configured in a WYSIWYG designer instead. It stops at the direction, with no code, no API and no packaging steps: new execution features will target the new framework and the legacy POD architecture will gradually phase out, while the designer, custom dialogs, dynamic PODs and notifications are left to the fifteen later posts the series list names.ManoelCosta, published 2026-02-10
