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.
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

DRY CAP – Making Sustainable Solutions Through PluginsDRY CAP – Making Sustainable Solutions Through PluginsA Devtoberfest 2026 building-apps session on packaging the things you would otherwise write twice, from in-house API clients and shared data models to validation logic, as a CAP plugin. The presenter builds one live: a cds-plugin.js next to package.json is what makes CAP notice the plugin at all, an index.cds carries a reusable user context and service that the consuming application projects into its own and protects there, and the plugin registers an Express middleware at a chosen step of the bootstrap to put user properties on the request. A feature-flagging plugin his team already uses closes it, and the whole walkthrough is the edge to Plugin authoring.SAP Developers, published 2026-10-02
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
SAP AI Services - DOX - Gen AI with SAP CAP Plugin - Part 3SAP AI Services - DOX - Gen AI with SAP CAP Plugin - Part 3Building on Reusable components for CAP with cds-plugin by Daniel Schlachter, this part walks through a custom CAP plugin — a cds-plugin.js plus a lib_cap_dox.js helper — that authenticates against SAP's Document Information Extraction (DOX) service and calls its schema and job-status APIs to fill an entity from extracted document fields. It covers reading the service key from Cloud Foundry (cf service-key) for the OAuth token endpoint, and dynamically mapping DOX's header and line-item output onto CAP entity properties.sabarna17, published 2024-06-11
What's in Daniel Hutzel's brain?What's in Daniel Hutzel's brain?A Devtoberfest 2026 session in the building-apps track, in which Daniel Hutzel and DJ Adams work through what the CAP team is building for agents. A bookshop gets an MCP endpoint beside its OData one from a single annotation, with the plugin writing the coding agent's configuration itself; in the xt-travels sample five services that know nothing about each other are served over MCP and an agent does the orchestration the hand-built UI and its value helps used to do. Hutzel then annotates a service as an agent so the ReAct loop and the choice of model move into the CAP service, and finally drops MCP for a skill that teaches the agent CQL instead, which is where the edges to Serve your application over MCP, Agent tooling and Agent guidance come from. The mechanism under all of it, a plugin file in the package root and event handlers that can be added to any CAP service, is the edge to Plugin authoring.published 2026-10-02

CAP: Consume External Service - Part 1CAP: Consume External Service - Part 1Builds a CAP Node.js service from scratch that consumes the public NorthWind OData V4 service: cds import turns its EDMX metadata into a CSN model under srv/external, and a CatalogService projects Products from it with a custom READ handler that runs the request through cds.connect.to('NorthWind'). Shows the same projection working two ways — against a CSV mocked under srv/external/data with the <service>-<entity>.csv naming the framework expects, then against the real service once credentials.url is added to the CAP configuration and @sap-cloud-sdk/http-client is installed — and defers routing that connection through the Cloud Foundry Destinations service to the next post in the series.published 2020-05-26

Random Numbers and Probability Distributions in the ABAP Environments for 2508Random Numbers and Probability Distributions in the ABAP Environments for 2508Introduces CL_ABAP_PROB_DISTRIBUTION and CL_ABAP_PROB_DISTRIBUTION_DF34, new ABAP system classes that generate random numbers from a distribution — normal, lognormal, exponential, gamma, chi-squared, Poisson, binomial, Student's t, hypergeometric, geometric — rather than only the uniform spread CL_ABAP_RANDOM gives. The worked example builds customer payment dates clustered around a due date instead of spread evenly across it, which is the shape seed data needs to look real rather than merely present; the same classes also compute CDFs and quantiles for statistical tests like a t-test on payment lateness.

Not below SAP_BASIS 7.40 SP08, and not on [SAP S/4HANA Cloud Public Edition](external:sap-s4hana-cloud-public-edition) or [the SAP BTP ABAP environment](artifact:btp-abap-environment), where the classic transport check, the report and job calls and the cluster table `INDX` it rests on do not exist and the maintainer names gCTS as the answer instead. Only on a development system where every developer is trusted: each developer's GitHub token is kept in a cluster table encrypted with a key held in the same table, so anybody who can run ABAP on that system can read both, and the separation between author and reviewer holds only as far as that trust does. Not where the gate has to be unconditional — `#NOREVIEW` in a request's short text skips the check for that request, `ZTR_DISABLED` switches it off for a system, a check that cannot reach GitHub lets the release go on, and nothing checks who writes the marker.

Event roundtrips and visual fidelity stay with a live run: the documentation leaves those to the project's MCP server and to [abap2UI5 for VS Code](artifact:abap2ui5-vscode-extension). A class that builds view parts in helper methods without the handle idiom cannot be statically reconstructed, and the render gate is then skipped with a notice while the property gate runs on what was reconstructed. A screenshot is not a preview of the app: nothing round-trips, no event reaches ABAP, and a table filled by a SELECT photographs empty unless a mock JSON file sits beside the source.

Functional boundary The Level A–D grade merges SAP's two published files in the tool's own engine: it is an orientation rather than an ATC result and is left out of the signed audit pack, and the repository documents state by state where the grade is expected to differ from what the clean core ATC check reports. Nothing here runs ABAP Unit — on the RAP track that result is recorded from your own SAP system, and generated CAP tests run against mocks in an isolated runner rather than in a real SAP S/4HANA system. Tenants, organisation accounts, single sign-on, a self-hosted edition and write access through an API are deliberately not built, and one account has five analysis runs before a Gemini API key of its own is needed.

ABAP Development Automation with ARC-1 and GitHub WorkflowsABAP Development Automation with ARC-1 and GitHub WorkflowsA sample repository puts an ABAP package into GitHub with abapGit and connects GitHub Actions to ARC-1 on BTP through an API key with no write tools, so abaplint on the diff, ABAP Unit and ATC through SAPDiagnose, label-triggered Copilot and Claude reviews, and ST22 dump triage all run as checks on a pull request. The review case is PR #14, where a SAPRead of the activated method let Claude state that a direct SELECT from MARA was new in the PR and not yet active in SAP, which a diff-only review cannot know. The test gate reads activated objects, so a team that pushes before activation needs a sandbox or a pull-and-activate step, and pulling a merged change back into SAP is named as the next step, not built.published 2026-05-12

News from Custom Code Migration: ECC to SAP S/4HANA Powered by Agentic AINews from Custom Code Migration: ECC to SAP S/4HANA Powered by Agentic AIA Devtoberfest 2026 session (ABA-23) on what SAP has added to the ECC to SAP S/4HANA custom code migration tools, demonstrated across a live ECC and an S/4HANA system. The first half stays deterministic and explains static analysis in that process: the custom code migration app's scoping over ABAP test cockpit findings, an explain of a legacy report and of an S/4HANA simplification finding, and transferable quick fixes exported from the app and applied on the ECC system through the SAP GUI ATC transaction before conversion. The second half runs the S/4HANA custom code migration agent in ABAP Development Tools for Eclipse: GitHub Copilot drives the ADT MCP Server's ATC and quick-fix tools in a loop, SAP Joule for Developers, ABAP AI capabilities produces the AI code proposals behind it, and only the high-confidence ones are written into the code, the rest left as comments in one transport request.published 2026-09-28
Patterns for using LLMs in ABAP developmentPatterns for using LLMs in ABAP developmentLars Hvam compares eight ABAP development setups: assistance in SE80 or Eclipse, virtual files and MCP over ADT, a centrally managed MCP service, sandboxes, local Git, Git with read-only system context, and temporary ABAP systems for development and CI. The overview describes where source changes, review and system access happen, including abapGit synchronization and abaplint checks. It is dated March 2026; its risk, cost and autonomy ratings are the writer’s assessments.
Rethinking security for modern SAP solution landscapesRethinking security for modern SAP solution landscapesWhere risk goes when clean core moves custom logic out of SAP S/4HANA: into integration flows, CAP extensions, ABAP Cloud code and platform configuration, told through real attack stories, then scanning code, modelling attack paths, adding security gates to CI/CD pipelines and automating safely with Terraform. The scanning edge is to static analysis, the atlas's concern for security findings in ABAP code; the abstract lists the four surfaces and the four practices and describes none of them.

SAP BAIP, ABAP environment – How to build partner solutions and get them certifiedSAP BAIP, ABAP environment – How to build partner solutions and get them certifiedA Devtoberfest 2026 session on the two ways a partner ships an ABAP Cloud solution built on SAP BTP ABAP environment, which the session calls the ABAP environment of SAP Business AI Platform: software delivery, where an add-on product is published with the solution ID from SAP Store onboarding and the customer discovers and deploys it into their own system, and service delivery, where the partner operates the same add-on as a multi-tenant SaaS and a new version is deployed rather than published again. That is the ABAP environment edge; the static analysis edge rests on the quality steps shown in the landscape portal, where the Manage Continuous Testing app released with 2608 runs an ATC check variant against a configured system on a recurrence pattern, beside test product version builds and managed test tenants. The second half walks through the SAP Integration and Certification Center process and the three BTP certification options open to an add-on product.SAP Developers, published 2026-10-12
Taking Control of Clean Core: When to Use Project Kernseife in addition to Standard SAP ToolsTaking Control of Clean Core: When to Use Project Kernseife in addition to Standard SAP ToolsWalks through how SAP's standard path classifies custom ABAP extensions into Clean Core Levels A through D, running ABAP Test Cockpit against the Cloudification Repository's release status for each SAP object an extension touches, then feeding results into the RISE with SAP Methodology Dashboard in SAP Cloud ALM. Contrasts that with Project Kernseife, an open-source custom ATC check that lets a team override SAP's classification with project-specific rules, define its own successor objects (including custom wrappers), and expose a Score and Potential Score per finding through a CDS view for prioritizing cleanup — at the cost of owning and maintaining that classification. States which situations favor each: Kernseife where the standard rules are too rigid for the project's reality, the standard dashboard where cross-system comparability and low maintenance effort matter more.LBretschneider, published 2025-11-04

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
