Async processingSAP and community
Always in Sync — Field-level and event-driven side effects for reactive UIs in RAPAlways in Sync — Field-level and event-driven side effects for reactive UIs in RAPA Devtoberfest 2026 session on side effects in RAP — the declarations in a behaviour definition that tell a draft UI to reload what a change affected, instead of leaving the user to refresh the browser. Field-level side effects recalculate a total price from a determination when a booking fee is entered, including across the association from a child item up to the root entity, and a permissions side effect toggles a description field between read-only and editable; a global side effect is attached to a determine action, fires when the user presses Enter, and only one may exist per business object, which is why the prepare action and a second determine action cannot both carry it. The last part starts a long-running calculation through the background processing framework and raises a business event that the behaviour definition lists as a side effect source and the projection makes public, so the Fiori app is updated with a notification when the work finishes, whether it was triggered by the user or by an application job — the transactional model and the async processing side the edges rest on.published 2026-10-05
How to Build Application Jobs in SAP Business AI Platform, ABAP environmentHow to Build Application Jobs in SAP Business AI Platform, ABAP environmentA Devtoberfest 2026 session on the application job framework in the cloud ABAP environment, built from the repository objects outwards: a class implementing the new application job interface, whose public attributes become the parameters and select options, the application log object it writes to, a job catalog entry that lays out sections, groups and value helps, and a job catalog template that works like a report variant. The demo schedules and monitors runs in the Application Jobs Fiori app, starts a job from a RAP action through the scheduling API under a job user of its own, and debugs one through the template's run-for-testing entry. It closes on the alternatives for work that should not be a job — the background processing framework for short-running work, and RAP events consumed locally or sent over the event mesh — which is the async processing this session covers for SAP BTP ABAP environment.published 2026-09-28
S/4HANA Custom Development - What happens in case of errors in BAPIs or RAP BOs?S/4HANA Custom Development - What happens in case of errors in BAPIs or RAP BOs?A Devtoberfest 2026 session on what a custom S/4HANA process does when a BAPI or a RAP business object fails. It is framed from project work rather than product development, with the same issues and challenges turning up on project after project, and it offers the ABAP Processing Center, ABAP-PRC, as what fills the gap it names in modern ABAP development. The edges rest on the opening, which states the session's subject as errors in S/4HANA custom development, read as error handling on the ABAP door, and names that framework.SAP Developers, published 2026-09-21
Triggering Background Jobs from RAP Actions – A Practical GuideTriggering Background Jobs from RAP Actions – A Practical GuideWalks through a RAP business object whose Saver Class calls a function module IN BACKGROUND TASK from the save phase, and that function module in turn uses JOB_OPEN, SUBMIT ... VIA JOB and JOB_CLOSE to schedule a classic background job that finishes the long-running work, so the triggering UI transaction stays lightweight. The mechanism shown — an asynchronous function-module call plus a submitted executable report — is Standard ABAP background processing rather than ABAP Cloud's released scheduling APIs.Arshiya2, published 2026-04-15

A method to create an Adobe form attachment for a work item using the class concept.A method to create an Adobe form attachment for a work item using the class concept.Walks through an ABAP workflow class, ZCL_WF_PDF, whose methods call an Adobe form through a Form-Builder-generated function module, convert the returned PDF between hexadecimal string and binary with SCMS_XSTRING_TO_BINARY and SCMS_BINARY_TO_XSTRING, and attach it to a work item via SAP_WAPI_ATTACHMENT_ADD and SAP_WAPI_WRITE_CONTAINER, with the class, background-task and SWDD workflow steps shown in full. It explains document output's ABAP route, rendering a PDF through the Form Builder and getting it back into the program, and a route into attachments's ABAP side distinct from Generic Object Services: a file attached to an SAP Business Workflow work item instead.Mithun_Sharma1, published 2026-08-21
Custom Form with Custom Data Source in SAP Public Cloud (Grow with SAP)Custom Form with Custom Data Source in SAP Public Cloud (Grow with SAP)Builds a custom Adobe-based output form for SAP S/4HANA Cloud Public Edition when SAP ships no standard data source: a RAP business object exposes header and item CDS views through a service definition, one view marked as the form's data provider, and the layout is designed offline in Adobe LiveCycle Designer against the exported XML schema before upload and rendering back in the tenant. It draws the line against SAP Forms Service by Adobe on BTP, which the post sets aside in favour of building the form inside the S/4HANA Cloud system itself.Gourab_Dey, published 2026-01-15
On‑the‑Fly Excel Download in a RAP Fiori App — No Database Table, No Persistence, Pure CDS + ABAPOn‑the‑Fly Excel Download in a RAP Fiori App — No Database Table, No Persistence, Pure CDS + ABAPBuilds a CDS custom entity backed by an ABAP class that implements IF_RAP_QUERY_PROVIDER and assembles an XLSX workbook at request time — hand-built from Open XML parts with cl_abap_zip for multiple sheets, or in one line via cl_salv_table=>to_xml for one — then streams it to the browser through the @Semantics.largeObject annotation. The same annotation makes Fiori annotations render the field as a download link with no backing database table, trading the usual persisted-blob approach to document output for a file rebuilt fresh on every click.hemanthmj, published 2026-06-18
Print Preview from RAP Action with v4 OData and Multiple SelectionPrint Preview from RAP Action with v4 OData and Multiple SelectionA RAP action's implementation calls SAP Interactive Forms by Adobe through cl_fp for each of several selected keys, merges the resulting PDFs into one file, and returns it as base64 from the action result. A Fiori elements list report invokes the action for the current selection through a controller extension's editFlow.invokeAction, grouped as a single ChangeSet so every selected document is generated and merged in one round trip before the merged file is offered back to the user.Gxalmet, published 2026-01-10

Creating an SAP SD Billing Document Using a BAPI in SAP Build and Accessing It Through 'Joule Work'Creating an SAP SD Billing Document Using a BAPI in SAP Build and Accessing It Through 'Joule Work'Walks through the two pieces of connectivity a SAP Build Process Automation action needs to call an on-premise BAPI: mapping the virtual host to the internal S/4HANA host in Cloud Connector over the RFC protocol, and creating an RFC-type destination in the BTP cockpit so BAPI_BILLINGDOC_CREATEMULTIPLE becomes a selectable action. The resulting process creates an SD billing document from a sales document number and is reached through SAP Build Work Zone, including from the Joule Work mobile app.MrRaj, published 2026-06-29
Running AI agents against SAP ECC 6.0: lessons from building an in-system MCP serverRunning AI agents against SAP ECC 6.0: lessons from building an in-system MCP serverNicolasHernandez recounts building and running, over two years, an MCP server written in plain ABAP behind a single ICF node, for SAP ECC 6.0 and S/4HANA on-premise customers that the ADT MCP Server and SAP Joule for Developers, ABAP AI capabilities do not reach. Authorization runs as the calling user rather than a technical RFC user, a choice forced by a customer security team after an earlier version used a technical RFC user, and a later security review found a display-authority check applied uniformly across every write endpoint. The failure modes that cost the most time sat in RFC connectivity itself: RFC_READ_TABLE's empty-table exception collapsed into a false success, a where-used filter was applied only after the row limit, and BAPI calls treated an empty string and an absent parameter as different, silently wrong inputs.NicolasHernandez, published 2026-08-28

It compares the endorsed and allowed paths — the MCP Gateway on SAP Integration Suite reaching S/4HANA and ECC through RFC-based back ends under a 15-tool, 200,000-token limit, SAP-provided MCP servers through Joule Studio, the A2A protocol, customer-operated MCP servers allowed under FAQ Question 56, and the ADT MCP Server, whose 18 tools work only on development artifacts and are documented as not intended for productive use. It leaves open whether Section 2.2.2 covers ABAP code that calls a model from inside the system, since enforcement is defined at the API-traffic level rather than by a list of tools.published 2026-08-31

Once those two are in place, SAP Build lists the exposed BAPIs and RFCs for use in an action.MrRaj, published 2026-07-09
Agent access to ABAP codeSAP and community
ABAP + MCP: Let AI Do Real Development in Your SAP SystemABAP + MCP: Let AI Do Real Development in Your SAP Systemabap-adt-mcp is an open-source MCP server that gives an AI agent full ABAP development capability over ADT: it searches, reads, edits, activates and unit-tests objects, and runs ATC checks, on a connected S/4HANA Cloud or on-premise system, acting as the signed-in developer. It runs on abap-adt-api, the same REST client Eclipse's own ADT tooling uses, and sits beside SAP's own ADT MCP Server, shipped with ADT for VS Code and Eclipse under a different server key, and marianfoo's abap-docs, a read-only server over the ABAP Keyword Documentation and Clean ABAP. Each destination carries a policy — read-only, allowed packages, denied tables and tools — the server checks before every call, and an optional audit file logs each tool call with its outcome and policy gate.Willian_Saez, published 2026-09-03
ABAP and Agentic AI: The Hidden Problem in Real ProjectsABAP and Agentic AI: The Hidden Problem in Real ProjectsAI in SAP development splits on three questions, how the model gets context, where writing happens and who controls the setup: UI5 and CAP work in local files where git, reviews, tests and pipelines already gate a change, while on-stack ABAP writes land directly in a shared development system. Six patterns follow, framed after a paper by Lars Hvam, from AI in the IDE to off-stack development with abapGit, and the post settles on a hybrid where the agent reads the system over ADT or MCP and writes through a gated git flow. Read access alone is put at maybe 80 percent of the work, and what agent access to your code still lacks is named as tool governance: read-only defaults, package restrictions, blocking free SQL, per-user identity and auditing.published 2026-04-22
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

Both are new instances of what agent access to your code already covers for ABAP — reading and acting on a real system through ADT — reaching now into a transport's changes and a check run rather than only source and objects.thomasalexander_ritter, published 2026-07-21

The demo installs the extension, creates a destination, opens, creates and activates objects, runs ATC and ABAP Unit, and names the object types, domains among them, for which a developer still goes to Eclipse or SAP GUI. It also opens the extension's settings to turn on the ADT MCP Server and shows the tools a chat can call, with the object search and source code search tools listed as planned.published 2026-09-28
Agentic Loop with Joule for Developers and ADT MCP ServerAgentic Loop with Joule for Developers and ADT MCP ServerA Devtoberfest 2026 session from SAP's ABAP AI team that generates a RAP issue-tracker application by prompting a coding agent. It covers what SAP Joule for Developers, ABAP AI capabilities now ships as MCP tools and which assistants can reach an ABAP system's virtual filesystem, then does the setup twice: turning on the ADT MCP Server and pasting the Joule side-by-side tenant link in ABAP Development Tools for VS Code, and again in ABAP Development Tools for Eclipse, where the custom agent becomes custom instructions. The demo's subject is the guardrails around the loop — an agent.md of phases and human checkpoints, skill files cloned from a GitHub repository for naming, ATC compliance and UI annotations — run through GitHub Copilot until the generated objects are activated, unit-tested and in a transport.SAP Developers, published 2026-09-28
AI-assisted SAP development with MCPAI-assisted SAP development with MCPA Devtoberfest 2026 session (UI-41) that traces AI-assisted SAP development from pasting code into a chat window to coding agents with built-in connectors, and sorts the MCP servers around SAP development into SAP's own, the community's and the hosted ones, where the agent cannot change what the server allows. Four demos follow: GitHub Copilot alone explaining an ABAP report from a Git repository, @ui5/mcp-server reading an OpenUI5 sample app and converting it to TypeScript, mcp-sap-docs grounding Terraform files for a BTP subaccount the presenter had not written before, and arc-1 with Copilot in Eclipse tracing why a title longer than 40 characters is rejected and proposing the DDIC-allowed length instead. It ends on a skill that migrates an SAP Gateway project on an ECC system to RAP on S/4HANA step by step, and on a rule Marian Zeis gives for servers written for internal use: keep them read-only, because what the agent is short of is context.published 2026-10-16
ARC-1 1.0: One Deployment, Multiple SAP SystemsARC-1 1.0: One Deployment, Multiple SAP SystemsThe release post for ARC-1 1.0, whose largest addition is an experimental multi-system mode: one BTP Cloud Foundry deployment attaches the SAP systems or clients an administrator selects through destinations, each with its own MCP address and an optional combined one, beside 22 included skills, an extension framework for company-specific tools, the BTP login code split out as @arc-mcp/xsuaa-auth, and a move to the ARC MCP organisation. It names the contributions behind the release: Wouter Lemaire for the first Cloud Foundry deployment and the first multi-backend implementation, Sami Bouguerra for NetWeaver 7.50 fixtures and activations that looked successful but were not, Clément Ringot for BTP login and Cloud Connector fixes, and Geert-Jan Klaps for S/4HANA Public Cloud support. It places SAP's own ADT MCP Server as the choice for a developer inside VS Code or Eclipse and ARC-1 as a shared service on BTP, and it stops short of a licence answer: the ADT web endpoints are not listed as published APIs in the SAP Business Accelerator Hub, so readers are told to ask SAP whether their agreement allows third-party tools to use them before a broader or production rollout.published 2026-08-03
ARC-1 on SAP BTP: Secure ABAP Agentic Development Beyond the LaptopARC-1 on SAP BTP: Secure ABAP Agentic Development Beyond the LaptopThe BTP deployment of ARC-1: one Cloud Foundry app per SAP system, reached by MCP clients through XSUAA and reaching the backend through the SAP Destination service, the SAP Connectivity service and Cloud Connector, with a BasicAuth destination for startup probing and a Principal Propagation destination for per-user requests, and SAP_PP_STRICT=true so a propagation problem fails instead of falling back to the shared user. Tool governance is the three gates it spells out, the server ceiling set by environment variables, the user's permission from XSUAA role collections, OIDC scopes or API-key profiles, and the SAP backend authorisation, all of which must allow an action, and the staged rollout from read-only to writes in $TMP, then selected packages, then transport writes. It recommends the MTA deployment over Docker on Cloud Foundry or a buildpack push, treats BTP ABAP Environment as a separate service-key scenario with no Cloud Connector, and is not a full setup guide: the commands are left to the ARC-1 deployment docs.published 2026-04-29

The test agent combines SharePoint specifications, Jira tickets and mcp-sap-docs with ARC-1 in six scenarios: a patch for a Jira bug proposed before it is applied, the impact of widening a domain from CURR 13,2 to CURR 23,2, a two-layer CDS view built from a specification, an ATC and abaplint quality report, a short dump diagnosis, and a clean core check that proposes released successors for direct selects on USR02 and BUT000. The access path and security model are those of the BTP part unchanged; the advice is to start this audience read-only, although the showcase itself enabled the read and write tools.published 2026-05-04

Two read-only showcases carry the ABAP Cloud readiness edge: a clean core check of one class that reports it is not released, uses USR02 and BUT000 directly and has no ATC findings, and a modernisation backlog for package ZSD_LEGACY which, as that package did not exist, grouped 28 ZSD* objects into risk buckets instead. The route through SAP Integration Suite API Management or a future MCP gateway is presented as a target architecture and not yet a productive setup, because Joule Studio's documentation requires streamable HTTP destinations and does not support MCP servers that need interactive OAuth user authorisation.published 2026-05-06

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.

How I Use AI for Development and Why Context MattersHow I Use AI for Development and Why Context MattersPart one of the AI ABAP development series traces a move from pasting ChatGPT output and error messages back and forth to tools that search, read docs and inspect files themselves, and holds that the context around a model decides more in real projects than benchmark results do. In SAP work the grounding comes from mcp-sap-docs, which brings SAP Help, GitHub repositories, style guides and DSAG guidelines into the session, and context for changing a class also means the tables it uses, the classes it calls and similar implementations. Agentic autonomy is a slider set per project, with the time saved on typing moved into planning and review, and the post stops before ABAP: SAP's MCP servers for UI5, CAP and Fiori (@ui5/mcp-server, @cap-js/mcp-server, @sap-ux/fiori-mcp-server) sit in off-stack work that git and pipelines already gate, and the harder ABAP case is left to the next part.published 2026-04-20

Intelligent App Development at Scale: SAP Fiori Elements + ABAP Development Tools for VS CodeIntelligent App Development at Scale: SAP Fiori Elements + ABAP Development Tools for VS CodeA Devtoberfest 2026 session (UI-33) that builds a RAP service and the SAP Fiori elements app over it from one VS Code workspace, with a coding agent driving two of SAP's MCP servers. The ABAP Development Tools for VS Code edges hold on the demo itself: its virtual file system keeps the ABAP package beside the Fiori project, the ADT MCP Server inside it creates, changes and activates the ABAP objects, and a version not yet released publishes the service binding from the agent instead of by hand. The @sap-ux/fiori-mcp-server edge covers its generators and the three-step workflow it uses for changes — list the functionality available for the application, ask for its JSON schema, then execute it — and the agent guidance edge rests on the skills the Fiori team publishes beside it, on the session's account of what a skill adds that a server does not, and on the analytical chart demo where a skill orchestrates both servers in one task.SAP Developers, published 2026-10-09
Introducing ARC-1: A Secure ADT MCP Server for Enterprise SAP DevelopmentIntroducing ARC-1: A Secure ADT MCP Server for Enterprise SAP DevelopmentWhy ARC-1 exists beside earlier ADT MCP servers such as vibing-steampunk, fr0ster/mcp-abap-adt and dassian-adt: one centrally deployed instance per SAP system instead of a server on each developer laptop, with the MCP client to ARC-1 hop and the ARC-1 to SAP hop authenticated separately. It sets out the restrictive defaults (read-only, no free SQL or named table preview, writes confined to $TMP), the layering in which ARC-1's configuration, the user's role and SAP's own authorisation must all allow an action, Principal Propagation so SAP sees the real user, and audit events to the SAP Audit Log service; that is tool governance as much as agent access to your code. It leaves the BTP setup to the next part, and places ARC-1 beside SAP's ADT MCP Server, which SAP's configuration guide describes as a local HTTP server hosted by the IDE, and beside SAP API Policy 4.2026a, where ARC-1's stated position is to stay close to documented ADT behaviour and ask SAP before production use.published 2026-04-27

Using Claude for SAP ABAP development on RFC-only / SAProuter systems (even ECC R/3)Using Claude for SAP ABAP development on RFC-only / SAProuter systems (even ECC R/3)vibing-steampunk gives Claude read, search, edit and check access to ABAP source over ADT's REST API, but some SAProuters permit only SAP's native RFC and DIAG routes and block raw HTTP to the ICM, so that link can't reach them even though Eclipse ADT can. Eclipse gets through because it tunnels ADT over RFC through the standard SADT_REST_RFC_ENDPOINT function module instead of HTTP, a path the post traces by capturing a live Eclipse session. adt-rfc-bridge reproduces that tunnel as a local HTTP-to-RFC proxy built on PyRFC, put in front of vsp, and the author reports it working on both S/4HANA and classic ECC/R/3 systems where Eclipse ADT already connects.enrico_andreoli, published 2026-06-09

ABAP development tools for Visual Studio Code is now available on the VS Code marketplace!ABAP development tools for Visual Studio Code is now available on the VS Code marketplace!Announces the marketplace release of ABAP development tools for Visual Studio Code, an extension that works against any ABAP system already reachable from ADT for Eclipse and is focused on RAP UI service development, so the Fiori/SAPUI5 frontend and the ABAP backend can be built in the same tool. It ships a built-in ADT MCP Server, disabled by default and switched on from the extension settings, and points readers to a documentation template for capturing ABAP-specific rules in a project's AGENTS.md file for chat agents such as Microsoft Copilot.thomasalexander_ritter, published 2026-06-01

The author still recommends duplicating the template and adding project-specific instructions, since the time spent on that onboarding is what the agent's results depend on.thomasalexander_ritter, published 2026-06-12

Where Claude got it wrong — a RAP scaffold missing the fields RAP's locking mechanism needs, ORDER as a reserved word — the piece asks where that knowledge would go as a Skill, and concludes Skills' filesystem basis has no home in a system reached only through MCP.k1000, published 2026-03-08
Intelligent App Development at Scale: SAP Fiori Elements + ABAP Development Tools for VS CodeIntelligent App Development at Scale: SAP Fiori Elements + ABAP Development Tools for VS CodeA Devtoberfest 2026 session (UI-33) that builds a RAP service and the SAP Fiori elements app over it from one VS Code workspace, with a coding agent driving two of SAP's MCP servers. The ABAP Development Tools for VS Code edges hold on the demo itself: its virtual file system keeps the ABAP package beside the Fiori project, the ADT MCP Server inside it creates, changes and activates the ABAP objects, and a version not yet released publishes the service binding from the agent instead of by hand. The @sap-ux/fiori-mcp-server edge covers its generators and the three-step workflow it uses for changes — list the functionality available for the application, ask for its JSON schema, then execute it — and the agent guidance edge rests on the skills the Fiori team publishes beside it, on the session's account of what a skill adds that a server does not, and on the analytical chart demo where a skill orchestrates both servers in one task.SAP Developers, published 2026-10-09

🟣 Bring AI into Your ABAP Applications with ISLM: Build, Integrate, and Consume AI Natively🟣 Bring AI into Your ABAP Applications with ISLM: Build, Integrate, and Consume AI NativelyDevtoberfest 2026 session AI-11, from the product manager and product owner of Intelligent Scenario Lifecycle Management: ISLM as the place an AI use case is registered, deployed and operated inside an SAP S/4HANA system, and what has been added to it for generative AI. The demo builds a custom scenario end to end — an intelligent scenario of type generative AI, a connection to SAP AI Core, a GPT-5 mini model, an orchestration flow template that configures data masking, input and output filtering and translation into the user's logged-in language, then prompts with a grounding query over five companies' return-policy documents — and consumes it from an ABAP report through the ABAP AI SDK, which calls the orchestration API and returns the summary as JSON. Two newer pieces follow: SAP RPT, the relational pre-trained transformer for tabular prediction, called with context rows and query rows and answering with a confidence value and no training step; and system-triggered agents, where an application job in the ABAP system starts a billing-creation agent that reaches S/4HANA OData APIs as tools through the agent gateway with principal propagation. The closing availability matrix states the generative AI capabilities for on-premise and private cloud from the 2021 release, with SAP notes to implement on lower ones.SAP Developers, published 2026-09-24
🟣 Enable Your AI application to Run on Multiple Models to Ensure Resilience and Compliance🟣 Enable Your AI application to Run on Multiple Models to Ensure Resilience and ComplianceDevtoberfest 2026 session AI-21. A cross product owner on the SAP AI Core team gives the reasons an AI application ends up on more than one model — a model down at the hyperscaler, a data centre that is not allowed to run it, a version being deprecated — and runs a joke app that answers from Gemini 2.5 Flash in EU10 and from Claude 4.5 Haiku in Asia-Pacific. The walk through AI Core's parts is where the edges hold: prompts kept as templates in the prompt registry, imported through the launchpad and the APIs or synced as YAML from a git repository (Prompt management); the evaluation service scoring one prompt across up to four models per run on built-in or model-as-judge metrics, and the prompt optimizer generating variants against one metric (Agent evals); and the orchestration service harmonising the providers behind one message format with a priority-sorted fallback list (LLM integration). The session also states where a metric has to be designed rather than picked: an exact-JSON match scores an email generator at zero, so the joke app's custom metric judges topic and family-appropriateness instead.SAP Developers, published 2026-10-01

The nodes carry the other edges — the human-in-the-loop node is built on SAP Task Center, and SAP AI Core is where model providers are configured centrally instead of per developer.

Building Code-Based AI Agents on the BAIPBuilding Code-Based AI Agents on the BAIPA Devtoberfest 2026 session on writing the agent yourself rather than configuring one, which is the agent tooling edge: an agent is a model with tools, skills, memory and context around it, and the session reads the code of one built in CAP as a LangGraph state graph, with an agent node that calls the model, a tools node holding the MCP clients, and the edge between them looping until no tool is needed. It then shows the shorter route, a CDS service annotated for the agent protocol with its instructions and skills in an agent.md file. SAP AI Core carries both, with the CAP service in front of it as middleware so the credentials never reach the browser, and that is what cap-agent-ui5-webui is demonstrated against: added as a dependency, it gives the annotated service a UI5 chat interface that can be deployed rather than only previewed. A Python multi-agent application on Cloud Foundry, where an orchestrator delegates to per-stack specialists so no single model sees every tool, closes the session.published 2026-10-09
Calling Claude from ABAP: How I Wired SAP AI Core into a Real Business ScenarioCalling Claude from ABAP: How I Wired SAP AI Core into a Real Business ScenarioA proof of concept wiring SAP AI Core's Claude deployment directly into ABAP with no CAP layer between them: two SM59 HTTP destinations, a hand-written OAuth 2.0 client-credentials exchange, and a regex to unwrap Claude's system/messages response envelope. Most of the effort goes into a system prompt that constrains the model to return one fixed JSON schema of filter fields, which ABAP deserialises with /UI2/CL_JSON and exposes through a RAP custom action so a Fiori search field can drive an OData V4 filter.PranayGaroo, published 2026-06-04
CAP in the age of AI #3 - from MCP to A2ACAP in the age of AI #3 - from MCP to A2AThe episode that finishes @cap-js/mcp with authorisation and then crosses to agents. @requires and @restrict are the same annotations CAP already has, and the plugin reads them to filter the tool list and the describe output per user and per request, so a model is not told about entities the caller cannot reach — where the OData metadata of the same service lists every exposed entity regardless. The second half annotates a service with @agent from @cap-js/agents, which serves it over A2A with an agent card and a chat preview, runs first against a mocked response and then against SAP AI Core bound with cds bind and a hybrid profile, and reuses the MCP adapter's tools rather than defining new ones.published 2026-08-21
CAP in the age of AI #6 - vector embeddingsCAP in the age of AI #6 - vector embeddingsVector embeddings put to work in the incident management sample, answering whether this problem has been seen before. An embedding element of type Vector is calculated and stored from the vector_embedding function, so the database refreshes it whenever the text behind it changes, and cosine_similarity compares it with a freshly embedded string; because a title says little, a scheduled action first summarises each incident's conversation through a model on SAP AI Core and the embedding is taken from that summary. The similar-incidents list is a view joining incidents to themselves, with order and limit set in a before handler on the expanded query, and the vector element excluded from the service, since OData knows nothing about vectors — on SAP HANA Cloud the function is native, while SQLite needs packages added to the project.published 2026-10-09

HANA itself can be given SAP AI Core as a remote source for other embedding models, which a CDS.ql expression has to inject because the postfix notation only takes what the CDS model holds, and the hour ends with a search function over cosine similarity exposed over @cap-js/mcp, so an agent asked about low output from solar panels calls semantic search instead of writing the query itself.published 2026-10-16
How to implement business AI capabilities in ABAP CloudHow to implement business AI capabilities in ABAP CloudA Devtoberfest 2026 session (ABA-32) on embedding AI in an ABAP Cloud application and on making SAP Joule aware of what that application can do. The first demo implements two features of a RAP travel app with the ABAP AI SDK: a determination on an uploaded receipt that sends the image together with the allowed categories and transaction types to a model reached through an intelligent scenario, then writes the extracted description, category, currency and amount back to the expense entity; and a recommendation function, triggered by a side effect on the trip title, that proposes a trip type with a score the Fiori UI sorts the proposals by and leaves the business user to accept — which is LLM integration from ABAP code. The second demo builds a capability for SAP Joule in the Joule Studio code editor in VS Code, with a scenario that extracts a trip title from the user's intent and calls an OData service in the ABAP backend through a BTP destination, deploys it and asks the Joule test UI for the trip's details; the session states that agents reach ABAP only over governed remote APIs — OData, SQL and MCP — and that automatic grounding of custom OData services in the knowledge graph is upcoming rather than available.published 2026-10-05
Unlocking Tabular Foundation Models: From Experimentation to ProductionUnlocking Tabular Foundation Models: From Experimentation to ProductionA Devtoberfest 2026 session (AI-41) on taking tabular prediction from a playground to a deployment. It sets tabular foundation models against a model trained per use case and against language models reading rows as text, explains in-context learning as examples plus the rows whose target column is missing, and tries SAP RPT 1.6 on a train-delay dataset in the RPT playground, including the column and row importance it returns with the prediction. The same prediction is then rebuilt on SAP AI Core, where the tabular orchestration service plays the part the orchestration service plays for language models: a data destination, a table artifact with its CSN schema and a scenario configuration registered once at design time, after which a predict call passes only the query rows, the scenario configuration and a context-selection strategy. The last demo runs those same calls in natural language through the aicore-skills plugin in a coding agent, and one of them only resolves once the agent is told which scenario configuration to use.SAP Developers, published 2026-10-15
What an AI infra engineer sees when opening SAP's AI stack (1/3): the model gatewayWhat an AI infra engineer sees when opening SAP's AI stack (1/3): the model gatewayA first look at SAP AI Core's Generative AI Hub from someone who builds gateways outside SAP for a living: the orchestration service harmonizes provider calls onto one API (a model name string switches providers, and SAP Note 3437766 carries the current model list, token rates and deprecation dates), runs a fixed, non-reorderable module pipeline — templating, masking through SAP Data Privacy Integration, grounding, content filtering, then the model call — and retries down an ordered fallback list whose entries can each carry their own model and rules. It places @sap-ai-sdk/orchestration among the official JavaScript, Java and Python SDKs, and notes SAP's own LiteLLM provider as a way to put a different gateway in front of it.amishkush, published 2026-09-30

A Clearer View of Your SAP Integrations Under the New API PolicyA Clearer View of Your SAP Integrations Under the New API PolicyThe SAP API Policy Evidence Skill assesses one SAP interface or usage pattern at a time against SAP API Policy v.4.2026a, reading evidence from five MCP servers, among them servers for the Business Accelerator Hub and SAP Notes, mcp-sap-docs and a read-only ARC-1, and returns one of four labels with a confidence level, an evidence table, residual risk and questions for SAP. It gives no compliant or not compliant answer on purpose, because SAP's FAQ (Q49) declines to publish a binding decision matrix, and it sends legal, commercial and roadmap questions to SAP and lowers its confidence when a source is not connected. Four sample runs show the method, among them ODP-RFC extraction labelled likely not aligned under SAP Note 3255746 and the same API_SALES_ORDER_SRV assessed differently for an autonomous agent behind a custom gateway and for a Boomi middleware flow; the SAP Notes and Business Accelerator Hub servers read SAP sites through a browser login, which the post says to use at your own risk.published 2026-06-02
ABAP + MCP: Let AI Do Real Development in Your SAP SystemABAP + MCP: Let AI Do Real Development in Your SAP Systemabap-adt-mcp is an open-source MCP server that gives an AI agent full ABAP development capability over ADT: it searches, reads, edits, activates and unit-tests objects, and runs ATC checks, on a connected S/4HANA Cloud or on-premise system, acting as the signed-in developer. It runs on abap-adt-api, the same REST client Eclipse's own ADT tooling uses, and sits beside SAP's own ADT MCP Server, shipped with ADT for VS Code and Eclipse under a different server key, and marianfoo's abap-docs, a read-only server over the ABAP Keyword Documentation and Clean ABAP. Each destination carries a policy — read-only, allowed packages, denied tables and tools — the server checks before every call, and an optional audit file logs each tool call with its outcome and policy gate.Willian_Saez, published 2026-09-03
ABAP and Agentic AI: The Hidden Problem in Real ProjectsABAP and Agentic AI: The Hidden Problem in Real ProjectsAI in SAP development splits on three questions, how the model gets context, where writing happens and who controls the setup: UI5 and CAP work in local files where git, reviews, tests and pipelines already gate a change, while on-stack ABAP writes land directly in a shared development system. Six patterns follow, framed after a paper by Lars Hvam, from AI in the IDE to off-stack development with abapGit, and the post settles on a hybrid where the agent reads the system over ADT or MCP and writes through a gated git flow. Read access alone is put at maybe 80 percent of the work, and what agent access to your code still lacks is named as tool governance: read-only defaults, package restrictions, blocking free SQL, per-user identity and auditing.published 2026-04-22
ARC-1 on SAP BTP: Secure ABAP Agentic Development Beyond the LaptopARC-1 on SAP BTP: Secure ABAP Agentic Development Beyond the LaptopThe BTP deployment of ARC-1: one Cloud Foundry app per SAP system, reached by MCP clients through XSUAA and reaching the backend through the SAP Destination service, the SAP Connectivity service and Cloud Connector, with a BasicAuth destination for startup probing and a Principal Propagation destination for per-user requests, and SAP_PP_STRICT=true so a propagation problem fails instead of falling back to the shared user. Tool governance is the three gates it spells out, the server ceiling set by environment variables, the user's permission from XSUAA role collections, OIDC scopes or API-key profiles, and the SAP backend authorisation, all of which must allow an action, and the staged rollout from read-only to writes in $TMP, then selected packages, then transport writes.

Introducing ARC-1: A Secure ADT MCP Server for Enterprise SAP DevelopmentIntroducing ARC-1: A Secure ADT MCP Server for Enterprise SAP DevelopmentWhy ARC-1 exists beside earlier ADT MCP servers such as vibing-steampunk, fr0ster/mcp-abap-adt and dassian-adt: one centrally deployed instance per SAP system instead of a server on each developer laptop, with the MCP client to ARC-1 hop and the ARC-1 to SAP hop authenticated separately. It sets out the restrictive defaults (read-only, no free SQL or named table preview, writes confined to $TMP), the layering in which ARC-1's configuration, the user's role and SAP's own authorisation must all allow an action, Principal Propagation so SAP sees the real user, and audit events to the SAP Audit Log service; that is tool governance as much as agent access to your code. It leaves the BTP setup to the next part, and places ARC-1 beside SAP's ADT MCP Server, which SAP's configuration guide describes as a local HTTP server hosted by the IDE, and beside SAP API Policy 4.2026a, where ARC-1's stated position is to stay close to documented ADT behaviour and ask SAP before production use.published 2026-04-27
