An introduction to CDS Graphical Modeler for SAP Business Application StudioAn introduction to CDS Graphical Modeler for SAP Business Application StudioThe announcement of the graphical modeller, from the team that built it — what it draws, how to get a dev space that has it, and what it is for. The starting point for the two posts that follow it, and the record of when this became part of the editor rather than an idea.Xiao-fei_Song, published 2021-04-23

Making CAP Application Development Easier and Faster with the Help of Storyboard in SAP Business Application StudioMaking CAP Application Development Easier and Faster with the Help of Storyboard in SAP Business Application StudioThe Storyboard from the other side — someone who came across it while learning the high-productivity tools, rather than someone who shipped it.

BTP CAP : Custom plugin to separate generic change log capture logicBTP CAP : Custom plugin to separate generic change log capture logicWalks through building a custom [CAP](ecosystem:cap) plugin that centralises change-log capture: on cds.once('served') it collects entities annotated @audit, then hooks srv.before('UPDATE') to read the existing record, diff it field by field against the incoming payload, and record old/new values with the user and timestamp. It also documents a cds build failure packaging the plugin's own directory into gen/srv for MTA deployment, fixed by adding it as a copyfiles build-parameter step in mta.yaml.sreehari_vpillai, published 2023-05-10
How to build reusable plugin components for CAP Java applicationsHow to build reusable plugin components for CAP Java applicationsA companion to Daniel Schlachter's Reusable components for CAP with cds-plugin, showing the same mechanism on CAP Java: a plugin ships as its own Maven artifact with an event handler and a CdsRuntimeConfiguration implementation, registered through the JDK's ServiceLoader rather than any CAP-specific wiring. The walkthrough builds a cds-emoji-plugin-java jar that decorates @emoji-annotated fields on read, installs it to the local Maven repository, and adds it as a runtime dependency to a cds init --add java bookshop application. It argues the plugin mechanism was not new to CAP Java, just previously undocumented.robinjayasinghe, published 2023-05-16
Reusable components for CAP with cds-pluginReusable components for CAP with cds-pluginThe post that taught the mechanism, and it teaches it by picking a requirement small enough to be absurd: every string a service returns should end in a random emoji. Working through that on the bookshop example leaves nothing to argue about except the plumbing, which is the point — what a cds-plugin is, where it hooks in, and why packaging it beats copying it into the next project. Vinícius Barrionuevo credits this post as the thing that gave him the idea for sap-cap-sdm-plugin, and it is hard to read the plugin ecosystem in this graph without it.published 2023-04-30

The library handles service lifecycle — starting the app, assigning a port, driving the browser and authenticating a named user — and its OData steps know the service's entities and fields from the CDS model itself, so a scenario can open a list report, search it and assert row counts without hand-written glue code.published 2023-10-10

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. What it says about arranging a UI5 app holds whatever model sits behind the chat; the tooling around it is of its date, and the post calls UI5's TypeScript support experimental.published 2023-02-27

Workflow integration has changed twice since this was published, most recently in @cap-js/n8n 0.0.1, 2026-08-27. Affects Runnable code.
Extensions for SAP Build Process Automation - Actions from CAP Node.js ServiceExtensions for SAP Build Process Automation - Actions from CAP Node.js ServiceThe direction of travel reversed: the CAP service is the thing being called, exposed as an Action so that a no-code process can consume it. Short by design — it is an introduction to a developer tutorial, and it says outright that the goal is to cover every step rather than to model a real use case.TJe, published 2023-01-13
SAP Build Process Automation – Use Principal Propagation in Actions sample: CAP Node.js ServiceSAP Build Process Automation – Use Principal Propagation in Actions sample: CAP Node.js ServiceThe follow-up that carries the identity through. It takes the CAP service from the Actions tutorial and puts the calling user's identity behind it — an XSUAA instance, a trust configuration, an OAuthSAMLBearerAssertion destination, and the service changed to use that instance — so a step runs on behalf of a person rather than as the process.TJe, published 2023-06-22

Trigger Build Process Automation Instance from S/4 HANA On-Premise using ABAP CodeTrigger Build Process Automation Instance from S/4 HANA On-Premise using ABAP CodeWalks through triggering a SAP Build Process Automation process instance by hand from an S/4HANA on-premise system: an SM59 destination of type G obtains an OAuth token from the process's service key, and an ABAP class with two methods — fetching that token and calling the triggering API — is exercised from a test SE38 program, with the full code left in the author's GitHub repository. The instance ID and status come back from the call, and completing the approval itself happens in the SBPA Monitor's Inbox app rather than in anything the post builds.Aashish28, published 2023-07-07
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

GenAI Mail Insights - Leveraging the generative AI hub in SAP AI Core to improve customer supportGenAI Mail Insights - Leveraging the generative AI hub in SAP AI Core to improve customer supportA sample application rather than an explainer, and the author says so in the opening — enough talking, here is something that runs. Incoming support mail summarised and categorised through the generative AI hub in AI Core.martinfrick, published 2023-11-15
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
