E2E: SAP Cloud Platform Internet of Things to SAP Analytics CloudE2E: SAP Cloud Platform Internet of Things to SAP Analytics CloudDevice data from ingestion to chart, with CAP occupying the middle: a CDS-defined persistence on HANA Cloud, and an OData service published from it for Analytics Cloud to consume live. The interesting choice is that CAP is used for the model rather than for business logic — there is barely any.Gunter, published 2020-08-31
Empowering Your Data Analytics with GPT-3 and SAP CAP IntegrationEmpowering Your Data Analytics with GPT-3 and SAP CAP IntegrationFree text in, SQL out, answer back in a sentence — the model writes the query, CAP runs it, and the model turns the rows into prose. Written in the GPT-3 window, so the model access has dated, but the three-step shape has not, and it is a different bet from retrieval: nothing is embedded, the schema is the context.Former Member, published 2023-03-10

Building an Attachment Upload and Download Solution Using UploadSetwithTable ControlBuilding an Attachment Upload and Download Solution Using UploadSetwithTable ControlThe successor control to UploadSet posts the file in one request by default, and against CAP that is wrong: the record has to be created first and the content put to it afterwards. The author states the two-step shape plainly and notes it may not apply to an ABAP backend, which is the kind of boundary that usually goes unsaid. Written during a proof of concept for a reusable attachment component, and it carries the problem they hit with the control.published 2025-03-13

Connecting Two SAP CAP Projects Without Duplicating Your DataConnecting Two SAP CAP Projects Without Duplicating Your DataCross-container HDI synonyms, argued from the alternatives rather than presented as a recipe: copying the table, standing up an API, or hard-coding the values are the three things the author reports seeing teams do, and each is named as working but unclean. With synonyms in place the consuming project queries the owner's HANA tables through ordinary SQL and ordinary CAP service code, with no replication and nothing to drift between environments. Covers the same ground as Mio Yasutake's 2021 post from a different angle — that one enumerates four topologies, this one argues for one of them.Inderpreet, published 2026-07-08
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

The abstract names the suite, SAP Build and the ABAP Cloud model and no single feature, so the edges are to Extensibility, the concern, and to SAP Build Code, the SAP Build solution held here in which Joule generates and deploys development; which other SAP Build solutions the session shows is not stated. A TechEd 2026 session (Tuesday 27 October, Berlin), presented by Alexander Rother and Khaled MUSILHY, written here from SAP's abstract; the recording is not yet published.
Get familiar with your first CAPM project using CDS graphic modelerGet familiar with your first CAPM project using CDS graphic modelerThe modeller as an entry point rather than an aid — a first CAPM project built by drawing it, for the developer who has not yet internalised CDL, annotations and metadata.Jyoti_ranjan, published 2025-07-05
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. It follows the whole arc a CAP project takes through the tool: entities, relationships, services, sample data, a UI, roles, and external resources, each as a thing the diagram can add rather than a file you open.Aryan_Raj_Sinha, published 2023-09-20

Storyboard for cloud business applications using CAP in SAP Business Application StudioStoryboard for cloud business applications using CAP in SAP Business Application StudioThe first release of the Storyboard, written by the team shipping it. Where the graphical modeller draws the data model, this draws the application: its logical components and the connections between them, alongside an application explorer enhanced in the same release. Short, and it reads as an announcement — the fuller account of using it is Aryan_Raj_Sinha's post two years later.liat_b, published 2021-02-15
Streamlining CAP Development with CDS Graphical Modeler in SAP Business Application StudioStreamlining CAP Development with CDS Graphical Modeler in SAP Business Application StudioThe case for the graphical modeller stated as a scale problem rather than a preference: a model held only as code gets hard to keep in your head once it is large, and the diagram is a second view of the same file. The most recent write-up of the tool here, and the one that treats it as an everyday working aid rather than as a new feature.Jyoti_ranjan, published 2025-07-16
Tips and Tricks for Working with Annotations in CAP Projects using Language Server Protocol (LSP) capabilitiesTips and Tricks for Working with Annotations in CAP Projects using Language Server Protocol (LSP) capabilitiesFour settings, from somebody who works on the annotation language server. The premise is the interesting part: CAP's annotation syntax is looser than ABAP CDS or EDMX — a record can be written with or without an explicit type — so the completion has to guess how verbose you want it, and this is where you tell it. Then filtering the completion list, reading the icons, ordering diagnostics by severity, and turning i18n problems on only when you want them.maryana_naboka, published 2021-10-25
GeneratorsSAP and community
CAP Initializr: Generate SAP CAP Projects in SecondsCAP Initializr: Generate SAP CAP Projects in SecondsA hosted project generator for CAP in the shape of Spring Initializr — pick the structure, dependencies and configuration in a browser and download the result, rather than running cds init and then wiring the facets by hand. The post is an MVP announcement asking for feedback, and the tool lives at a Cloud Foundry trial URL rather than on npm, so it is a direction being tested in public rather than something to depend on.Saptarshi017, published 2026-03-23

Introducing eslint-plugin-better-cap-config an ESLint plugin to improve CAP configurationIntroducing eslint-plugin-better-cap-config an ESLint plugin to improve CAP configurationThe author's own announcement, and precise about scope: today it catches deprecated key/value entries in CAP's JSON configuration, and the ambition is that it grows into best practices, suggestions and autofixes the way any ESLint plugin does. The implementation detail worth knowing is that it uses modern ESLint's JSON language support rather than a generic parser, which is what makes linting a configuration file rather than source code work at all.published 2025-09-08

What moved: it became a CAP plugin, gained UI5 Tooling support, and moved to the async launchpad — each framed as keeping pace with where SAPUI5 itself is going rather than as a feature.published 2023-12-11

Plugin authoringSAP only
AI needs a foundation: A map of the plug-in ecosystem for CAPAI needs a foundation: A map of the plug-in ecosystem for CAPA map of the plug-ins for CAP (@sap/cds), official, community and independent, drawn across regions such as integration, performance and tooling, so that a team can see what exists to reuse and what it would have to build: the question plugin authoring answers from the other side. SAP's abstract places CAP at the centre of its AI strategy, with model context protocol support, and the map is offered as the foundation under that. A TechEd 2026 session (Tuesday 27 October, Community Theater, Berlin), presented by Mike Zaschka, written here from SAP's abstract; the recording is not yet published.
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

Add useful Extensions to Dev spaces in SAP Business Application StudioAdd useful Extensions to Dev spaces in SAP Business Application StudioStarts from the point capire makes — that CAP is editor-agnostic and BAS is the preconfigured option — and then does the thing that undoes preconfiguration: adds two extensions to a dev space for initialising data in a CAP application, with the uninstall procedure as well as the install. The uninstall half is what makes it worth keeping.showkath_naseem, published 2022-11-13
Avoiding Data Loss When Loading Initial Data with CSV Files in CAPAvoiding Data Loss When Loading Initial Data with CSV Files in CAPcds add tiny-sample gives you a CSV in db/data and it loads on deploy, which looks like a way to seed a productive application.

(Part 2 of 3)The middle part of three, and the one about SAP: where TypeScript is supported across a side-by-side extension on BTP, as of July 2023. It says the SAP Cloud SDK already generates OData clients as .ts files and UI5 ships types for its controls and modules, the ground of TypeScript support in UI5, while CAP offers standard types and the new @cap-js/cds-typer generates types for a service, which is typing, with the caveat that running cds-ts commands could overwrite what cds-typer generated.MikeDoyle, published 2023-07-05
