Working with the Attachment plugin - Cloud Application ProgrammingWorking with the Attachment plugin - Cloud Application ProgrammingOne instalment of the author's own series working through the CAP plugins one at a time, and it reads as that: what the plugin does, how it does it, and how to put it in a service. Written from the plugin list in capire rather than from a problem, which makes it the plainest introduction here.published 2024-05-18

Performance Boost and Caching Strategy for Faster Data Access using "cds-caching" in SAP CAPPerformance Boost and Caching Strategy for Faster Data Access using "cds-caching" in SAP CAPSomebody else's account of using the plugin, which is the useful counterpart to its documentation. The case is specific: a master-data entity of more than a million rows, rarely written and constantly read, where the read-heavy shape is what makes caching worth the complexity rather than a general performance wish. Walks through integrating cds-caching into that application and what it changed.NaveenChandar, published 2025-03-04

Getting started with CAP on PostgreSQL (Node.js)Getting started with CAP on PostgreSQL (Node.js)Running CAP on PostgreSQL locally in 2020, when doing so meant the community packages cds-pg and cds-dbm. It now opens with a banner the author added later: @sap/cds 7.0.0 has native PostgreSQL support, use @cap-js/postgres instead, with a pointer to a step-by-step guide for it. Worth having for that banner as much as for the content — a post that tells you not to follow it is a dated fact about where the answer moved.published 2020-11-16

Kept because that notice is the record of when the community adapter stopped being the answer.shanthakumar_krishnaswamy, published 2023-04-04

From SEGW and Legacy UI5 to RAP with ARC-1From SEGW and Legacy UI5 to RAP with ARC-1Three ARC-1 skills, run in Cursor with Composer-2 against a deliberately rough demo on an S/4HANA 2023 trial system, turn the SEGW service ZDEMO_MIG_PROJECTS_SRV into a managed, draft-enabled RAP business object published as OData V4, replace its ApproveProject function import and its direct UPDATE ... COMMIT WORK with the action approve_project written in EML in local mode, and rebuild the freestyle UI5 JavaScript app once in UI5 TypeScript and once as a Fiori elements list report and object page driven by metadata extensions. What the published transcripts add is how the agent got there: it found the generated MPC class names and the custom logic in DPC_EXT only by reading the system, the skills made it print the extracted model and stop for confirmation before writing, and @ui5/mcp-server, mcp-sap-docs and @sap-ux/fiori-mcp-server each had their own job beside it. The demo is small on purpose, and the post says a productive SEGW service that calls BAPIs, carries custom authorisation logic or supports deep inserts is not solved with one prompt.published 2026-05-11
