Custom Functions in OData V4 – SAP Cloud Application Programming ModelCustom Functions in OData V4 – SAP Cloud Application Programming ModelFunctions rather than actions, and the distinction is where it starts: a function must return data and must never change any, so it is the read-only half of custom operations. Then how to declare and implement one on a CAP service.Roopa_N, published 2021-04-28

How to add OData v2 adapter proxy to your CAP projectHow to add OData v2 adapter proxy to your CAP projectThe problem is stated in one line — a UI5 application that only speaks OData v2 in front of a CAP service that speaks v4 — and the answer is a proxy in the middle rather than a rewrite of either end. Written while v4 support in the UI5 stack was still patchy, which is the whole reason the adapter exists.published 2020-06-30

How to share tables across different CAP projectsHow to share tables across different CAP projectsFour scenarios for reading one CAP project's table from another, worked out as a matrix of what each one needs: the same HDI container and namespace, the same container under a different namespace, a different container, and a different Cloud Foundry space. The mechanics change with each step — @cds.persistence.exists on the reused entity throughout, an .hdbsynonym once namespaces diverge, .hdbrole and .hdbgrants once containers do, and a user-provided service built from the grantor's credentials once spaces do. The author flags the caveat themselves: these are learning scenarios, and consuming the OData service is often the better answer than reaching into another project's database. Dated corrections from twelve days after publication sit inline — synonyms need only the name because the configuration comes from .hdbsynonymconfig, SERVICE_REPLACEMENTS in mta.yaml removes the hard-coded service name, and the reused container need not be bound to the srv module.published 2021-10-03

PostgreSQL persistence adapter for CAP (Node.js)PostgreSQL persistence adapter for CAP (Node.js)The contradiction the adapter was built to resolve, stated plainly in 2020: CAP's core is open, non-intrusive and platform-agnostic, which is what would let it run outside SAP's world — except that HANA was the only officially supported production persistence and HANA exists only inside BTP. cds-pg is the answer to that, and this is the post that argues for it. Read now as the front end of a story whose other end is the 2023 post recording cds-pg's deprecation in favour of @cap-js/postgres.published 2020-08-20

Enable App-to-App Navigation in BASEnable App-to-App Navigation in BASTesting navigation between two Fiori applications inside Business Application Studio, which Web IDE Full-Stack made easy and BAS initially did not. Two paths: between Fiori elements applications it is a few clicks in Fiori tools with both apps in the same workspace, and for a freestyle application the same result takes a short sequence of manual steps. Written in 2021 against the Fiori tools of the time, so read the mechanism rather than the clicks.published 2021-05-24
