⚡Unlocking the Power of LLMs in CAP: Understanding llms.txt and llms-full.txt⚡Unlocking the Power of LLMs in CAP: Understanding llms.txt and llms-full.txtllms.txt and llms-full.txt for CAP — a plain-text map of the documentation, written for an agent that arrived by fetching a URL rather than one somebody configured. The convention the atlas uses for itself, applied to capire.Yogananda, published 2025-05-18
How I Use AI for Development and Why Context MattersHow I Use AI for Development and Why Context MattersPart one of the AI ABAP development series traces a move from pasting ChatGPT output and error messages back and forth to tools that search, read docs and inspect files themselves, and holds that the context around a model decides more in real projects than benchmark results do. In SAP work the grounding comes from mcp-sap-docs, which brings SAP Help, GitHub repositories, style guides and DSAG guidelines into the session, and context for changing a class also means the tables it uses, the classes it calls and similar implementations. Agentic autonomy is a slider set per project, with the time saved on typing moved into planning and review, and the post stops before ABAP: SAP's MCP servers for UI5, CAP and Fiori (@ui5/mcp-server, @cap-js/mcp-server, @sap-ux/fiori-mcp-server) sit in off-stack work that git and pipelines already gate, and the harder ABAP case is left to the next part.published 2026-04-20

An Innovative Language Exchange App developed with SAP Build Apps, CAP, Kyma, and OpenAIAn Innovative Language Exchange App developed with SAP Build Apps, CAP, Kyma, and OpenAIA dormant internal app at SAP Japan revived with AI, built to solve a problem the team actually had — colleagues who could not talk to each other. Build Apps on the front, CAP on Kyma behind it, OpenAI in the middle.javieryw, published 2024-01-31

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
Build a Business Application Using CAP for Node.jsBuild a Business Application Using CAP for Node.jsThe Node.js introduction path, and the shorter of the pair — the runtime most CAP writing assumes, which is why the Java path exists separately.SAP
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
Extending SAP Sales and Service Cloud V2 Using CAPExtending SAP Sales and Service Cloud V2 Using CAPAn extension target that does not run on BTP at all — Sales and Service Cloud V2 sits directly on hyperscalers — so the separation between core and extension is enforced rather than encouraged. That constraint is what makes the post worth reading.Quablab, published 2025-07-09
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
Full Stack TypeScript App for Cloud Foundry - Sample RepositoryFull Stack TypeScript App for Cloud Foundry - Sample RepositoryA whole repository rather than a snippet: a CAP Node.js service and a freestyle SAPUI5 application, both in TypeScript, arranged for Cloud Foundry. The build process gets its own section, which is where a TypeScript full-stack project usually goes wrong.former_member66, published 2021-12-09

The End2End Journey: Advocates Service – CAP Service, OData V2/4 & REST in One single ProjectThe End2End Journey: Advocates Service – CAP Service, OData V2/4 & REST in One single ProjectOne CAP service exposing OData V2, OData V4 and REST at the same time, which is unusual enough to be worth the read on its own. Part of an end-to-end series, deployed on Cloud Foundry against HANA Cloud, so the protocol question sits inside a whole application rather than a snippet.KRiedelsheimer, published 2021-05-06

UI5ers Buzz #56: New full-stack UI5 sample app featuring CAP + OData V4 + draft modeUI5ers Buzz #56: New full-stack UI5 sample app featuring CAP + OData V4 + draft modeA sample app published as code rather than described — SAPUI5 over a CAP service with OData V4 and draft mode — and the note that it was built on what the team learned from an application written in March 2020 to help the German Foreign Office repatriate citizens. That provenance is unusual and worth keeping.AndreasKunz, published 2020-11-06
