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
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
Build Your AI Agent prototype for free using SAP CAP, LangChain and Ollama cloudBuild Your AI Agent prototype for free using SAP CAP, LangChain and Ollama cloudA CAP Node.js service action calls an Ollama-hosted model through LangChain's ChatOllama, with the API key read from a .env file instead of any destination or credential binding — the hand-rolled-key route SAP's own SDK call exists to avoid. The same handler then builds a LangChain agent with createAgent and one mock tool, so a question about restaurants triggers a tool call and any other question does not, independent of the @cap-js/agents plugin's A2A-served harness.rajeevgoswami1, published 2026-08-29

It explains why the tool's Zod schema and model-facing description are the agent's actual contract, the gotcha between a foundation-models deployment and an orchestration-scenario one, and how edge-case testing replaced date inference with a server-computed daysOverdue field after the agent wrongly called a delayed order 'on schedule'.rodfior, published 2026-08-20

Calling Claude from ABAP: How I Wired SAP AI Core into a Real Business ScenarioCalling Claude from ABAP: How I Wired SAP AI Core into a Real Business ScenarioA proof of concept wiring SAP AI Core's Claude deployment directly into ABAP with no CAP layer between them: two SM59 HTTP destinations, a hand-written OAuth 2.0 client-credentials exchange, and a regex to unwrap Claude's system/messages response envelope. Most of the effort goes into a system prompt that constrains the model to return one fixed JSON schema of filter fields, which ABAP deserialises with /UI2/CL_JSON and exposes through a RAP custom action so a Fiori search field can drive an OData V4 filter.PranayGaroo, published 2026-06-04

The post walks through what shipping the CAP plugin and the be.wl.ai control library in one npm version buys — a client and server contract that cannot drift — then lists the eleven controls by group, shows the two-line configuration that activates each half, and notes that this version is actually deployed on BTP behind both a standalone approuter and Work Zone.

What an AI infra engineer sees when opening SAP's AI stack (1/3): the model gatewayWhat an AI infra engineer sees when opening SAP's AI stack (1/3): the model gatewayA first look at SAP AI Core's Generative AI Hub from someone who builds gateways outside SAP for a living: the orchestration service harmonizes provider calls onto one API (a model name string switches providers, and SAP Note 3437766 carries the current model list, token rates and deprecation dates), runs a fixed, non-reorderable module pipeline — templating, masking through SAP Data Privacy Integration, grounding, content filtering, then the model call — and retries down an ordered fallback list whose entries can each carry their own model and rules. It places @sap-ai-sdk/orchestration among the official JavaScript, Java and Python SDKs, and notes SAP's own LiteLLM provider as a way to put a different gateway in front of it.amishkush, published 2026-09-30

Two variants ship, a default model and a -large model recommended past 100 columns or where accuracy is the priority, and the post previews a coming "tabular orchestration" workflow, targeted for general availability in August 2026, that is meant to select the relevant context rows from millions of historical records automatically.RanjeetKr, published 2026-08-14

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

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

HANA AI Toolkit — Local MCP ServerHANA AI Toolkit — Local MCP ServerAn MCP server that turns the hana-ml Python library into governed tools an agent can call against a HANA Cloud instance, shipped in the hana-ai toolkit and exposed over stdio, SSE and streamable HTTP. Its one firm rule is attributable execution: an audit module writes the MCP-side identity — agent, model, session, tool, redacted arguments — into the HANA connection before any SQL runs, and fails the call if that write fails. A worked example of governance on an MCP tool surface, from SAP's data side rather than CAP's.published 2026-06-15
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

The BTP Destination service uses OAuth2JWTBearer to exchange the user's Cloud Identity Services JWT for an Integration Suite token, and the iFlow's OData V2 receiver adapter reaches S/4HANA through Cloud Connector with Principal Propagation authentication. The Cloud Connector Subject Pattern builds the outbound certificate's CN from the token's user_name claim, which is populated from the IAS email rather than the sub claim, so identity resolution on S/4HANA hinges on that email matching a resolvable logon name.Joni, published 2026-07-10

Authorization runs as the calling user rather than a technical RFC user, a choice forced by a customer security team after an earlier version used a technical RFC user, and a later security review found a display-authority check applied uniformly across every write endpoint. The failure modes that cost the most time sat in RFC connectivity itself: RFC_READ_TABLE's empty-table exception collapsed into a false success, a where-used filter was applied only after the row limit, and BAPI calls treated an empty string and an absent parameter as different, silently wrong inputs.NicolasHernandez, published 2026-08-28

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

SAP Cloud Integration (CI/CPI) - Reusable Script Collection Pattern for Sensitive Data MaskingSAP Cloud Integration (CI/CPI) - Reusable Script Collection Pattern for Sensitive Data MaskingOpens with the question compliance teams ask about Cloud Integration, whether an integration team based outside Europe with Message Monitoring access can read the personal data in a logged payload, and answers that in most standard configurations it can. The pattern against it is a reusable Groovy script collection plus one global variable holding the masking rules: a script near the start of an iFlow AES-encrypts the original payload into a header or property and replaces values in the body by value pattern first and field-name keyword second, a second script restores the original just before the sender, so a Log Payload step anywhere in the flow captures the masked body while the target system still receives the real data. The post names its own limits, that pattern-based masking is heuristic and that CPI trace can capture the payload before the scripts run, and grounds the pattern in GDPR Articles 5(1)(f), 25, 32 and 44-49, reading the EDPB's Guidelines 05/2021 to mean that access from a country without an EU adequacy decision, uncovered by Standard Contractual Clauses or another valid transfer mechanism, can itself constitute a cross-border transfer.AdarshRao, published 2026-05-25

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

Covers the API artifact's Content Modifier policy that injects the Business Accelerator Hub API key before the backend call, and the "Trust Upstream MCP Authorization" setting that lets the MCP server delegate authorization checks to that source API instead of duplicating them. Ends by fetching an OAuth token from a Process Integration Runtime service key and pointing an MCP client at the deployed server over streamable HTTP.published 2026-07-13

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

Event-driven SideEffects push over a WebSocket channel through @cap-js-community/websocket, while Draft handling gains ABAP RAP's live field locking on CAP Node.js through Sören Leibach's own cap-collaborative-draft plugin. Both rest on Fiori annotations such as Common.SideEffects and CollaborativeDraft.enabled, which the frontend reads rather than requiring a manifest flag.published 2026-07-09
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

Deep Insert in SAP CAPM Using Composition and Fiori ElementsDeep Insert in SAP CAPM Using Composition and Fiori ElementsParent and children created in one transaction, which composition already gives you in the model — the post is about what Fiori elements does with it, and what the payload looks like when the UI sends both at once.published 2026-05-22
Dynamic Criticality in SAP CAP Using Fiori Elements and Node.jsDynamic Criticality in SAP CAP Using Fiori Elements and Node.jsColouring rows by status, which sounds like a UI question and is not: criticality is a value the service has to compute and expose, so the work is a virtual element in CDS and the annotation that points at it. Comes from a real requirement — business users wanting to spot the records that need attention.Pranesh_SD, published 2026-06-05
Fullstack CAP Application with HANA Cloud (Decoupled Architecture) [Part-2]Fullstack CAP Application with HANA Cloud (Decoupled Architecture) [Part-2]Part 1 left a working OData service whose Fiori preview showed nothing useful. This is the annotations that fix that — the UI vocabulary added to the CDS model until the generated list report has columns worth reading.sanjucs, published 2026-05-07
On‑the‑Fly Excel Download in a RAP Fiori App — No Database Table, No Persistence, Pure CDS + ABAPOn‑the‑Fly Excel Download in a RAP Fiori App — No Database Table, No Persistence, Pure CDS + ABAPBuilds a CDS custom entity backed by an ABAP class that implements IF_RAP_QUERY_PROVIDER and assembles an XLSX workbook at request time — hand-built from Open XML parts with cl_abap_zip for multiple sheets, or in one line via cl_salv_table=>to_xml for one — then streams it to the browser through the @Semantics.largeObject annotation. The same annotation makes Fiori annotations render the field as a download link with no backing database table, trading the usual persisted-blob approach to document output for a file rebuilt fresh on every click.hemanthmj, published 2026-06-18

Establish a central entry point with SAP Build Work ZoneEstablish a central entry point with SAP Build Work ZoneSAP's reference architecture for a business site in SAP Build Work Zone, standard edition or SAP Build Work Zone, advanced edition as one entry point to business applications, processes, information and communication, on the web or in the Joule Work mobile app. Three of its eight flow steps are how content gets in, the ground launchpad and site content covers: custom apps through the channel to the subaccount's SAP HTML5 Application Repository service for SAP BTP, other content through content providers that expose it over APIs from cloud or on-premise systems and content packages uploaded as files, and SAP Cloud Transport Management or manual export and import to move it between environments. Users and role assignments come from Cloud Identity Services, and the components inside the subscription, among them Notifications, SAP Mobile Services and UI Theme Designer, cannot be decoupled from the product, so a custom mobile app needs its own SAP Mobile Services subscription.published 2026-05-22
How to Deploy a Custom Fiori App to S/4HANA Public Cloud and Add a Tile in SAP Build Work ZoneHow to Deploy a Custom Fiori App to S/4HANA Public Cloud and Add a Tile in SAP Build Work ZoneA step-by-step walkthrough of taking a RAP-based Fiori app from SAP Business Application Studio deployment to a working tile in SAP Build Work Zone, standard edition on SAP S/4HANA Cloud Public Edition: the crossNavigation/inbounds block in manifest.json that creates the Launchpad App Descriptor Item, the IAM App that links it to a Business Catalog and Business Role, and the semantic-object-and-action intent Work Zone resolves against. SSO between BTP and S/4 works because both trust the same Cloud Identity Services tenant.sushweta_bhattacharya, published 2026-05-28
Creating a Custom F4 Help for Currency Fields in ABAP Using F4IF_INT_TABLE_VALUE_REQUESTCreating a Custom F4 Help for Currency Fields in ABAP Using F4IF_INT_TABLE_VALUE_REQUESTWalks through building a custom F4 help popup for a currency selection-screen field: an AT SELECTION-SCREEN ON VALUE-REQUEST handler reads currency codes and texts from TCURC and TCURT into an internal table, then passes it to F4IF_INT_TABLE_VALUE_REQUEST to render the popup list. It is offered as a replacement for the field's standard search help when that does not fit the business requirement.vinodkumarreddyappannagari, published 2026-06-03
SAP MDG Cloud Ready Mode: 5 Solution Patterns, Zero BADIs: How We implemented 5 typical requirementsSAP MDG Cloud Ready Mode: 5 Solution Patterns, Zero BADIs: How We implemented 5 typical requirementsA field report from an 80%-complete SAP MDG-BP Cloud Ready Mode implementation, showing five requirements it met without BAdIs or modification: business-partner context and the MDG UI shown inside the My Inbox app, rule-based multi-step approval routing with exclusive-choice nodes, agent determination through BTP role collections, and role-specific Fiori App Variants that give Finance Experts only bank-detail fields while Approvers get full write access. Each pattern works the same way underneath — a BTP Workflow service task reads business-partner attributes over OData into the workflow context, and a user task, route or app variant reacts to it — built with key-user extensibility or SAP Business Application Studio rather than custom ABAP.steffen_ulmer, published 2026-06-01

Trigger an SAP Build Process Automation Workflow from CAP Using the @cap-js/process PluginTrigger an SAP Build Process Automation Workflow from CAP Using the @cap-js/process PluginA step-by-step setup for starting a Build Process Automation workflow from CAP through the plugin rather than through direct REST calls, which is how it had to be done before. Covers both ends: deploying the process in the SBPA designer and finding the workflow instance id it produces, then wiring the CAP side to it.

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
