⚡Unlocking the Power of LLMs in CAP: Understanding llms.txt and llms-full.txt⚡Unlocking the Power of LLMs in CAP: Understanding llms.txt and llms-full.txtllms.txt and llms-full.txt for CAP — a plain-text map of the documentation, written for an agent that arrived by fetching a URL rather than one somebody configured.

Enhancing Unit Testing in SAP CAP Java Applications with GitHub CopilotEnhancing Unit Testing in SAP CAP Java Applications with GitHub CopilotBuilt on SAP's own CAP Java unit-testing guide, and the question is narrow: how much of that does an assistant actually write for you.

Github Copilot VSCode - My Own SAP Development RulesGithub Copilot VSCode - My Own SAP Development RulesOne developer's rule files for Copilot, split by concern rather than kept as one prompt: CAP backend rules, UI5 frontend rules, Jest testing rules and Bruno collection rules, each with a scope narrow enough that an agent cannot read it two ways. The CAP file covers reusable types, managed data, soft-delete behaviour and service conventions; the UI5 file covers naming, view constraints and where annotations may live. It is the rule-file half of agent guidance rather than the skill half — nothing is packaged or published, and the value on offer is the shape of the split.radu_simen, published 2026-02-05
Teaching AI Agents Best Practices: A Skills Workspace for CAP DevelopmentTeaching AI Agents Best Practices: A Skills Workspace for CAP DevelopmentStates the gap this capability exists for more precisely than most: an agent already knows CAP well enough to generate models, handlers and deployments, but knowing a framework and following its current practice reliably are different things, because a model defaults to whatever it saw most of during training — which may be outdated, subtly wrong, or simply not how a given team works. Skills are offered as the closing mechanism, and the post describes a workspace pattern rather than a single file, with the architecture claimed to be framework-agnostic.daniel_schlachter, published 2026-06-09

Adapting SAP Joule for Purchase Order Creation from an Existing Purchase RequisitionAdapting SAP Joule for Purchase Order Creation from an Existing Purchase RequisitionA custom Joule Agent and Joule Skill, built in Joule Studio, classic edition to extend SAP Joule past its built-in Purchase Order display and change features: a buyer's single sentence naming a Purchase Requisition number becomes a created Purchase Order, with the skill wrapping the Purchase Requisition and Purchase Order OData V4 APIs as Action Packages reached through two destinations. The author anchors the agent's success condition to a PurchaseOrderNumber in the skill's output rather than an HTTP status code, and reports that the Purchase Requisition item structure does not map one-to-one onto the Purchase Order creation payload.jonathanvi59, published 2026-08-19
Agentic AI on BTP: a Multi‑Agent App with Pydantic AIAgentic AI on BTP: a Multi‑Agent App with Pydantic AISplits a single CAP/TypeScript agent that had grown to juggle five BTP MCP servers behind one bloated tool list into btp-multiagent-app, a Python and Pydantic AI rewrite where the Cloud Foundry and BTP Core MCP servers each get a dedicated specialist agent, with an audit log specialist scaffolded but left disabled, behind an orchestrator whose only tools are delegation calls to those specialists, which is the agent-tooling pattern the piece works through. Each specialist authenticates to its MCP server over Streamable HTTP with OAuth 2.1, and a shared module centralises the SAP AI Core GenAI Hub model setup behind two credential layouts, one for local runs and one for the Cloud Foundry service binding, the LLM integration side of the rewrite. Tool lists per agent drop from well over a hundred to a dozen or two, and routing failures become separable from tool-misuse failures by reading the trace.published 2026-05-03
Agentic AI on BTP: a Single Agent with LangGraphAgentic AI on BTP: a Single Agent with LangGraphA CAP TypeScript agent puts a LangGraph StateGraph in front of AzureOpenAiChatClient from @sap-ai-sdk/langchain, reaching SAP AI Core's Generative AI Hub, and lets its tool-calling loop draw on five deployed MCP servers — OData MCP Proxy, CI MCP Server, AI Core MCP Server, BTP MCP Server and BTP CF MCP Server — through @langchain/mcp-adapters' MultiServerMCPClient. Because agent, servers and APIs share one XSUAA tenant, the chat service forwards the signed-in user's own JWT instead of a service account, so each downstream server enforces that user's own authorizations. Past roughly a hundred combined tools the single prompt slows down and stops separating concerns, which is why the author's next post splits it into one specialist agent per MCP server behind an orchestrator.published 2026-05-03

Building Custom Joule Skills via RFC: Guide for SAP S/4HANA and ECC IntegrationBuilding Custom Joule Skills via RFC: Guide for SAP S/4HANA and ECC IntegrationWalks a Joule skill from a spoken question about a production order's status to an answer in SAP Build Workzone: a Cloud Connector tunnel and a destination in the BTP cockpit reach the S/4HANA or ECC system, a BAPI/RFC Action Project in SAP Build wraps the BAPI that reads the order, and Joule Studio, classic edition turns the action into a skill and deploys it. Establishing the connection and its destination before the action project exists is RFC connectivity and Destinations done for a low-code consumer rather than a CAP service. The action type here is BAPI/RFC, alongside the OData actions Joule Studio's own entry names.Robin-Qiu, published 2026-04-01
Building Durable AI Agents - Announcing the cds-langgraph-persistence PluginBuilding Durable AI Agents - Announcing the cds-langgraph-persistence PluginThe announcement, and the argument behind it. Treating an agent as a software architecture rather than a model with tools makes a list of production requirements — identity, authn and authz, multitenancy, persistence, event-driven flows, scalability, observability, CI/CD — and the author's point is that CAP already answers most of them for BTP, which is what makes LangGraph inside CAP Node.js worth doing. The post then narrows to one of those requirements, durability, and the checkpointer that supplies it. Written from a year of building agents next to real business systems rather than as a framework tour.merbinjanselm, published 2026-07-15

Explaining SAP Joule for HR Business Users & Functional Consultants.Explaining SAP Joule for HR Business Users & Functional Consultants.Written for HR business users and functional consultants, this walks through how SAP Joule is provisioned on SAP BTP and wired into SuccessFactors: the Joule instance sits in a BTP subaccount, SAP Build Work Zone is created alongside it, and Identity provisioning syncs users from SuccessFactors into Build Work Zone while Cloud Identity Services authenticates the launch through an IAS tenant. It lists five prerequisites for the connection — a BTP global account, a Joule entitlement, Cloud Identity Service and SuccessFactors admin access, and the right personas — and notes that running BTP's booster adds the Joule permission to the SuccessFactors user's profile.santanuray_learner, published 2025-03-23
How Redwood Software and SAP are shaping the next era of automation with Joule StudioHow Redwood Software and SAP are shaping the next era of automation with Joule StudioRedwood's Field CTO describes a tech preview where an SAP Basis administrator tells SAP Joule in natural language to pause background jobs and dependent Integration Suite iFlows for unplanned system maintenance; Joule acts as a control tower, triggering a pre-approved RunMyJobs workflow and asking for approval before the restart proceeds. The integration is built by publishing RunMyJobs operations to the SAP Business Accelerator Hub, securing access through SAP BTP with API keys and role-based permissions, and combining those actions into a skill inside Joule Studio's low-code design canvas.gmblom, published 2025-11-02

SAP Joule implementation in an S/4HANA private cloud 3 system landscapeSAP Joule implementation in an S/4HANA private cloud 3 system landscapeWalks through enabling SAP Joule across a three-system S/4HANA Private Cloud landscape (DEV, QAS, PRD) rather than the common single-system setup: separate BTP subaccounts for the non-production systems, a shared Cloud Identity Services tenant, and catalogs and roles transported from DEV through QAS to PRD. Covers single sign-on for Joule by setting Microsoft Entra ID as the corporate identity provider in SAP IAS, so authentication flows through Entra ID without the user existing in the IAS store, plus principal propagation through the Cloud Connector into the production backend.Arunrajj, published 2026-01-21

Cloud Integration with Document AICloud Integration with Document AIWalks through connecting Cloud Integration to SAP Document AI: an iFlow posts a prescription PDF to Document AI's job API, polls the job endpoint until it completes, and a groovy script reads back the result, keeping only the fields above a stated 60% confidence threshold.

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
Using BTP Document Extraction Service into actual App developmentUsing BTP Document Extraction Service into actual App developmentWalks through calling SAP Document AI's REST API directly: getting a client-credentials bearer token from the service key's UAA, then POSTing to /document/jobs with a file and an options body naming the document type and the header fields and line items to extract (paymentTerms, documentDate, taxId, description for an invoice), and polling the returned job id until the status resolves. Covers the trial-account booster and its own UI for uploading a document and testing extraction before moving to Postman and a small Python script that lists jobs over the same bearer token.Ace_D, published 2024-07-31
What a Second Document AI Workshop Taught Me About GovernanceWhat a Second Document AI Workshop Taught Me About GovernanceFrom questions raised at a second SAP Document AI workshop: the retention period for extracted data is a setting in the service's administration rather than a fixed property, with the source file deleted after processing and the decommissioning period for the extracted data configured to the customer's own policy. It also draws a boundary readers kept merging: Document AI extracts across languages but does not translate, so turning a document into a reviewer's own language is a separate step, pointing on BTP at SAP Translation Hub.Nicolas_BacaStorni, published 2026-08-25

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.

Tool governanceUnmapped
MCP Servers are the New Z-TablesMCP Servers are the New Z-TablesA single CAP service exposed as three overlapping MCP servers tools, queried by the same prompt nineteen times, returned the same tool every time — evidence, the author argues, that tool selection rests on the resemblance between a prompt and a tool's description rather than on any binding a where-used list could enumerate before retiring it. It contrasts that setup with @cap-js/mcp, which exposes a whole service as three generic tools instead of one per operation, and quotes the adapter's own beta documentation admitting no rate limiting, audit logging, input validation or approval workflow, and no use as a gateway to SAP Application APIs. From there it names four small Tool governance practices it has adopted: an owner recorded in the tool's own metadata, logging every invocation, deprecating inside the description, and exposing fewer tools.published 2026-08-21

Securing SAP CAP Applications: XSUAA, Roles, and Authorization Best PracticesSecuring SAP CAP Applications: XSUAA, Roles, and Authorization Best PracticesWalks through securing a CAP service end to end: declaring scopes and role templates in xs-security.json for the SAP Authorization and Trust Management service (XSUAA), restricting CDS service definitions with @restrict per role, and dropping into handler code where a rule needs custom logic, with a @sap/cds Node.js example that tests roles through req.user.is and a Java one that tests scopes through hasScope. It closes in the BTP cockpit, where a role collection is assigned to users so that their JWT carries the scopes those checks read.Soumya-Pirlamarla, published 2025-07-14

Data privacyUnmapped
#SAPCAP: Win Customer Trust using Data Privacy and Protection Services on BTP - Part 1#SAPCAP: Win Customer Trust using Data Privacy and Protection Services on BTP - Part 1First of a three-part series on designing a CAP application on BTP that uses the platform's data privacy services, and this part is the vocabulary before any of it: personal data, the rights a data subject has under GDPR, and the data controller and processor distinction, worked through an order-confirmation SMS example. It names four BTP services: SAP Personal Data Manager, SAP Data Retention Manager, SAP Data Privacy Integration and SAP Audit Log service. Only the first is described, as a service running in the Cloud Foundry environment that finds data subjects across one or more applications and services, makes requests on an individual's behalf about their personal information and forwards them for handling, and notifies individuals which of their personal information is being used or sends them a copy of their record by email; the CAP-side annotations and PDM's own application features follow in Part 2 and Part 3.Ajit_K_Panda, published 2023-03-18
#SAPCAP: Win Customer Trust using Data Privacy and Protection Services on BTP - Part 2#SAPCAP: Win Customer Trust using Data Privacy and Protection Services on BTP - Part 2Walks through wiring a CAP service to SAP's Personal Data Manager (PDM) on BTP: entity, key and field-level @PersonalData annotations that mark data subjects and personal fields, the @PersonalData.IsPotentiallyPersonal / IsPotentiallySensitive distinction that drives audit logging, and the @Communication.Contact annotation PDM needs to search for a data subject. Covers the xsuaa trust arrangement and service binding that let the standalone PDM application call back into the CAP service to read and manage that data. Second of a three-part series; the annotation model it demonstrates is CAP's own mechanism for data privacy compliance, exercised against a sample 'Game Shop' application.Ajit_K_Panda, published 2023-03-18
#SAPCAP: Win Customer Trust using Data Privacy and Protection Services on BTP - Part 3#SAPCAP: Win Customer Trust using Data Privacy and Protection Services on BTP - Part 3Third of a three-part series, this covers the UI side of SAP's Personal Data Manager (PDM) once it is subscribed and wired to a CAP application: a Customer Service Representative searches for a data subject, views the personal data the application's annotations expose, and requests correction, deletion or export on their behalf, while an Operators Clerk processes those requests through to completion. PDM stores none of the personal data itself, only the requests and access logs, which an administrator downloads through the separate Data Transport app. It builds on the annotation model the first two parts introduce, so what it demonstrates is PDM's own delivered UI rather than anything a CAP application must build itself.Ajit_K_Panda, published 2023-03-18

CAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry is a prototype that generates a CAP Node.js project with SAP Fiori elements from a written business requirement, discovering the actual data shape from a chosen source — SQLite, a configured SAP HANA HDI container, offline EDMX, live OData through the SAP Destination service, or approved SAP BTP ABAP objects — instead of inventing one. The generated application can carry a Fiori draft lifecycle with optimistic concurrency via ETags and annotation-driven Fiori elements list and object screens, localized independently of the underlying service contract. Attachments can be added with upload, download and delete, gated on a malware-scan status, and the generated project still has to compile, build and pass its generated tests before the run is accepted.Shahid, published 2026-08-20

API Composition: Seamless Enterprise Data Access for Developers and AI AgentsAPI Composition: Seamless Enterprise Data Access for Developers and AI AgentsAPI Composition (formerly Graph, a capability of API Management) curates business data graphs from existing SAP and non-SAP API providers, so a query can navigate and expand relationships across systems through one composed API rather than hand-written integration code. Palak walks through combining SAP S/4HANA warehouse-stock data with Everstream Analytics risk data into one API, then exposing that composed API as an MCP server so an AI agent calls it with the same semantic context — the scenario behind API Management's MCP servers coverage.published 2026-07-27
