Consume Remote Services in a Full-Stack CAP ApplicationConsume Remote Services in a Full-Stack CAP ApplicationExtending the Developer's Guide application with a remote S/4HANA service — connectivity, importing the Business Partner API, and running against it. SAP publishes this as four separate paths: mock server or real S/4HANA Cloud, times Cloud Foundry or Kyma. One entry covers all four, because the difference between them is which backend and which runtime, not what you learn.SAP
Extend SAP SuccessFactors on SAP BTP with the SAP Cloud Application Programming ModelExtend SAP SuccessFactors on SAP BTP with the SAP Cloud Application Programming ModelTwelve tutorials, about two hours, building a side-by-side extension of SuccessFactors on BTP. The spine is remote services: importing the SuccessFactors OData service definitions into a CAP model, then treating them as entities the extension reads and writes through, rather than as an API called from a handler. Indexed as one entry because the parts only make sense in order.SAP

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

Natural Language Queries for SAP CAP via MCP: The LLM Translates, CDS ExecutesNatural Language Queries for SAP CAP via MCP: The LLM Translates, CDS ExecutesThe division of labour is the argument, and it is in the subtitle: the model turns English into a CDS query and CDS runs it, so nothing generates SQL and nothing hallucinates a join.

The Easiest Way to Expose a CAP Node.js Project as an MCP ServerThe Easiest Way to Expose a CAP Node.js Project as an MCP ServerFrom cds init to a running MCP server in a handful of steps, ending at the MCP Inspector so the result is something you can see rather than something you have to trust. The claim it makes for the plugin is the absence of work: no REST wiring by hand, the CAP application exposed as a server because the package is installed. A walkthrough rather than an argument — the reasoning about what should be exposed lives elsewhere.Jacky Liu, published 2026-07-03

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

How to Restrict CRUD Operations in SAP CAPM Using @Capabilities, @readonly and Test APIs with .httpHow to Restrict CRUD Operations in SAP CAPM Using @Capabilities, @readonly and Test APIs with .httpEntities are exposed with full CRUD by default, and this is how to take operations away again — @Capabilities for Insert, Update and Delete individually, @readonly for the blunt version. Tested with .http files rather than a UI, which keeps the check on the service.DeepaRagho, published 2026-05-22

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
Develop a Full-Stack CAP Application Following SAP BTP Developer's GuideDevelop a Full-Stack CAP Application Following SAP BTP Developer's GuideThe eight-part path SAP's own Developer's Guide prescribes: a CAP service, Fiori Elements over it, custom logic, authorization, tests, and the preparation deployment needs. It is the closest thing to an official answer to 'what does a whole CAP application look like', which is why it sits under reference applications rather than under any one of the capabilities it touches.SAP
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

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. Written against the first beta, released 26 April 2026, so the shape is settled but the surface may not be.Jacky Liu, published 2026-07-02

Build a Business Application Using CAP for JavaBuild a Business Application Using CAP for JavaThe Java counterpart to the Node.js path — eight tutorials, around two and a half hours, from a generated project to a running service. Worth having indexed separately rather than folded in with the Node.js one: the runtimes diverge most in exactly the places a first application touches, and following the wrong path is a slow way to find that out.SAP

From Concept to action: Hands-On with the CAP Operator and the Partner Reference ApplicationFrom Concept to action: Hands-On with the CAP Operator and the Partner Reference ApplicationThe CAP Operator applied to a real application rather than a sample of its own — SAP's Partner Reference Application, taken from plugin integration through containerisation to custom resources. The transition to CRDs is the part that repays attention: it is where the deployment stops being an mta and becomes Kubernetes.ChristianWeiss, published 2026-05-21
