[Blog Post] SAP Event Mesh - Consuming S4 events simultaneously in CAP-based applications and SAP Integration Suite[Blog Post] SAP Event Mesh - Consuming S4 events simultaneously in CAP-based applications and SAP Integration SuiteOne S/4HANA event, two consumers at once: a CAP Java application and SAP Integration Suite. Late in a long Deep Dive series and written as such — the queues, the S/4HANA connection and the Integration Suite side were all established in earlier posts, so this is the part where they meet.AyushKumar and vipul.khullar, published 2023-03-24

[Part - 1] Enrich CAP based Services with Behaviors using Annotations[Part - 1] Enrich CAP based Services with Behaviors using AnnotationsWalks through CDS annotations that add behaviour beyond CRUD: @readonly and @insertonly take away write, update or delete on an entity or element, each shown with the OData metadata it generates. @mandatory, @assert.unique, @assert.integrity, @assert.format and @assert.range then enforce input checks that @sap/cds runs on write, with the SQL or HANA constraint @assert.unique compiles to and the error code each rejection returns. It names @restrict and @requires but defers them, calling authorization too large a topic for this post.published 2023-01-28
[Part – 2] Enrich CAP based Services with Behaviors using Annotations[Part – 2] Enrich CAP based Services with Behaviors using AnnotationsThe second half of a two-part walkthrough of CAP's behavioral annotations, following on from access control and input validation in the first part. This post works through @cds.autoexpose, @cds.api.ignore, @cds.persistence.exists/skip, @cds.on.insert/@cds.on.update and the @odata.Type/@odata.singleton mapping overrides, all shaping how a CDS model is projected into a service, which is data modelling. Alongside these it covers @cds.query.limit for default and maximum page sizes (pagination and streaming), @odata.etag with exclusive and shared locks for optimistic concurrency (concurrency control), and @cds.search for scoping $search to chosen elements (search), each with a CDS code example.published 2023-01-29
#BTP #SAPCAP: Quirky Nuggets (N05-N06)#BTP #SAPCAP: Quirky Nuggets (N05-N06)On SAP BTP, Cloud Foundry Runtime, a one-shot PostgreSQL db-deployer app can be restarted by the platform's default port-type health check inside its 60-second timeout, re-running the deploy and duplicating data in the PostgreSQL database; setting health-check-type to process or http, via cf commands or the app's mta.yaml parameters, avoids it. In CAP, a remote service's entities are imported and consumed through cds.connect.to and queried via a projection, but its functions and actions cannot be projected: they must be redefined in the consuming service's own interface, with the handler forwarding the call to the remote proxy.published 2023-07-27

The second half is structure — a formatter class and a singleton LayoutManager called from the XML view through core:require, a confirmation helper taking a callback, a dialog class resolving a promise, a generic createEntity<T> on a service class — all of it to keep every controller under 100 lines.

Add MCP capabilities to a CAP serviceAdd MCP capabilities to a CAP serviceA fifteen-minute walkthrough of turning a plain CAP service into an MCP server: annotate the service with @mcp, install @cap-js/mcp, and it is served alongside OData at /mcp/<path>. The part worth reading it for is what happens next — cds watch writes the endpoint into the local agent's own configuration file, so OpenCode or Claude Code can call the service without anyone editing JSON by hand. It is built on the tiny-sample facet, so there is nothing to prepare, and it shows the protocol traffic rather than only the result. Written while the adapter was in beta, and it says so.published 2026-08-13

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

Building Durable AI Agents - Announcing the cds-langgraph-persistence PluginBuilding Durable AI Agents - Announcing the cds-langgraph-persistence PluginThe announcement, and the argument behind it. 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.

It then deploys to BTP and reads Risks with a client-credentials OAuth token fetched from a service key of the cpapp-auth instance, after changing that entity's READ grant from RiskViewer to authenticated-user, which the post, citing capire's CDS-based Authorization page, describes as a grant for a technical user integrating systems rather than for access from a front end.ArthurYang, published 2024-12-10
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 multitenancy with Work ZoneCAP multitenancy with Work ZoneA gap in the tooling and the manual edit that closes it. cds add portal wires the Portal service, which is deprecated; Work Zone supports multitenancy but has no equivalent command. The author runs the portal command anyway and then rewrites the resource and module config in mta.yaml to point at Work Zone. Short, and honest that it is a workaround rather than a supported path.published 2025-03-14

Document GroundingDocument GroundingDocument Grounding is a managed retrieval-augmented-generation service under the Generative AI Hub on BTP, which SAP's page on SAP AI Core places inside that service: it ingests documents from Amazon S3, SharePoint, SAP Document Management Service, SAP Work Zone or an SFTP server, and handles chunking, embedding and retrieval itself, refreshing content automatically when a source document changes.

Dynamic authorisation with user attributes in SAP CAP and AMSDynamic authorisation with user attributes in SAP CAP and AMSThe same argument as the XSUAA-to-AMS piece, opened from a concrete failure: an acquisition puts 500 users on sales data restricted by division, and role-based access control answers it with Sales_Manager_EMEA, Sales_Manager_APAC and so on until the roles multiply past managing. Attribute-based authorisation replaces the set with one policy carrying a restriction, and the post walks through defining it in AMS against Cloud Identity Services. The clearest statement of role explosion among the three AMS pieces here.pedro_iranzo, published 2026-05-04

Effective Axios Error Logging for Robust SAP IntegrationsEffective Axios Error Logging for Robust SAP IntegrationsTwo logged failures printed side by side, and the point is made by looking at them: one tells you what went wrong and one does not. Axios buries the useful part of an HTTP error, and this is what to unwrap before logging it from a CAP service.Sahil2508, published 2025-08-31
Effective from June 30th 2026 - XSUAA Deprecation of GET Method for OAuth Token RetrievalEffective from June 30th 2026 - XSUAA Deprecation of GET Method for OAuth Token RetrievalEffective June 30th 2026, the SAP Authorization and Trust Management service (XSUAA) deprecates the HTTP GET method for retrieving an OAuth access token from its /oauth/token endpoint, leaving only POST supported in line with RFC 6749. A client still requesting a token via GET with grant_type and credentials in the query string stops working after the cutover and must switch to a POST request with form-encoded body parameters.Yogananda, published 2026-06-14

Enhancing Business Processes with SAP BTP AI in SAP Integration SuiteEnhancing Business Processes with SAP BTP AI in SAP Integration SuiteWalks through a post-exit iflow in SAP Integration Suite that calls an LLM through SAP AI Core's Generative AI Hub to turn a customer's free-text return comment into one of a fixed set of SAP rejection-reason codes, so an inbound ORDERS05 IDoc carries a decision (E1EDP01-ABGRU) the ERP can act on without pausing for manual review. The worked example is a Commerce Cloud returns flow into S/4HANA; the piece argues the same bounded-classification pattern fits other narrative fields — delivery-exception remarks, expense-claim justifications — where the cost of an LLM call is repaid by removing a human review step, and points to a colleague's post on the Generative AI Hub orchestration workflow for the guardrailing (prompt templating, data masking) it only names.arunmaarirajha_kv, published 2025-12-15

The SuccessFactors APIs themselves are downloaded as EDMX files from SAP API Business Hub and imported into the CAP project, the same EDMX-import path behind service integration, so CAP generates the client used to call them.

Explaining SAP Joule for HR Business Users & Functional Consultants.Explaining SAP Joule for HR Business Users & Functional Consultants.Written for HR business users and functional consultants, this walks through how SAP Joule is provisioned on SAP BTP and wired into SuccessFactors: the Joule instance sits in a BTP subaccount, SAP Build Work Zone is created alongside it, and Identity provisioning syncs users from SuccessFactors into Build Work Zone while Cloud Identity Services authenticates the launch through an IAS tenant. It lists five prerequisites for the connection — a BTP global account, a Joule entitlement, Cloud Identity Service and SuccessFactors admin access, and the right personas — and notes that running BTP's booster adds the Joule permission to the SuccessFactors user's profile.santanuray_learner, published 2025-03-23

First Java Cap ApplicationFirst Java Cap ApplicationA step-by-step walkthrough of a first CAP Java project: com.sap.cds:cds-services-archetype scaffolds the initial Maven project, and the domain model is then rewritten in the db folder with entities, the cuid and managed aspects, associations, compositions and a CodeList, so a hand-coded event handler serving a single entity gives way to a service that CAP's generic persistence handling serves without custom code. It deploys that model to SQLite for local development — cds deploy --to sqlite, then a Spring profile pointing at the generated database file — and ends by adding an index.cds so the model and service can be published as a reusable npm module.bruce_wang3, published 2020-12-08
