Building a Real‑Time Currency Conversion iFlow using SAP Cloud Integration (CPI)Building a Real‑Time Currency Conversion iFlow using SAP Cloud Integration (CPI)A step-by-step build of a currency-conversion integration flow in Cloud Integration: an HTTPS sender adapter accepts JSON, a content modifier stores the currencies and amount as exchange properties, and a Request-Reply step calls an external rate API before a Groovy script renders the result as an HTML table. A Global Exception Subprocess centralizes error handling for the whole flow, turning the MPL ID, error type and message into HTML and mailing it as a notification to a support address.RajeshwerRao_G_1, published 2026-04-01
Connecting SAP Integration Suite with Slack: A Hands‑On Guide with Open ConnectorsConnecting SAP Integration Suite with Slack: A Hands‑On Guide with Open ConnectorsA walkthrough builds an integration flow on SAP Integration Suite that receives JSON over an HTTPS sender, transforms it with Groovy, and posts a formatted message to a Slack channel through the Slack Open Connector. An Exception Subprocess catches token, channel and connector-invocation failures and returns a structured error response, and the author verifies it by forcing a bad channel ID and confirming the error-notification email arrives.jareenabee_dudekula, published 2026-03-20

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
SAP CAP function and action with Unstructured/Dynamic Type Input/OutputSAP CAP function and action with Unstructured/Dynamic Type Input/OutputA CAP action or function can take or return an unstructured type: annotate the service @protocol: 'rest', declare the parameter or return value as @open type object {}, and a handler shapes the payload however a given request needs, shown here with a bound action and a function that returns a different structure per input. The text states plainly that OData V4 and GraphQL services require a fixed structure for action and function parameters, so the dynamic type works only over CAP's REST protocol.published 2022-12-08

Adding Immutable Blockchain Proofs to SAP With CAP - Cardano and OData V4Adding Immutable Blockchain Proofs to SAP With CAP - Cardano and OData V4The write-up behind ODATANO, by its author: how a public blockchain gets reachable from CAP as an ordinary OData V4 service rather than through a bespoke client. The premise it starts from is worth the read on its own — SAP systems are trusted but mutable, which is what an immutable anchor is for — and Cardano is chosen for peer-reviewed research and formal methods rather than for popularity.

The framework loads entity configuration, extracts the request context, fetches and transforms backend data into the target entity shape, and returns it through the RAP response object, with field mapping and conversion exits left for each subclass to fill in.AnslemArnolda, published 2026-04-07
OData $batch Deleting Records Across Multiple Tables in Single TransactionOData $batch Deleting Records Across Multiple Tables in Single TransactionWalks through implementing a multi-table DELETE inside a single OData v2 $batch changeset on SAP Gateway: setting cv_defer_mode = abap_true in CHANGESET_BEGIN so more than one delete is collected per change set instead of being executed immediately, looping the collected operations in CHANGESET_PROCESS to delete from each backend table in turn, and issuing one COMMIT WORK in CHANGESET_END so all tables commit or roll back together. The example is a supplier master spread across basic, address, identification and purchasing-organisation tables, deleted as one logical unit of work instead of one HTTP call per table.Abhi_0118, published 2026-04-17

The Fourth Way to Go Offline in UI5 (And Why the Service Worker Stays Dumb)The Fourth Way to Go Offline in UI5 (And Why the Service Worker Stays Dumb)Reporting on the UI5Con session run by Viktor Sperling and Lars Kissel, the post proposes a fourth offline architecture for a warehouse scanning app: a service worker kept deliberately ignorant of OData, and a JSONModel/IndexedDB layer that does an explicit download, work, submit cycle, queuing local mutations before posting one $batch with a single changeSet at the end of a session. It also works through the alternative v4.ODataModel change-buffer pattern (updateGroupId, submitBatch) and explains why Fiori elements' annotation-driven, live OData V4 interactions resist offline replay. The session-token and XSRF-expiry problem for long offline periods is named as an open gap rather than solved.Noel_Hendrikx, published 2026-07-15

What's new with draft handling in RAP?What's new with draft handling in RAP?An ABAP-day session at Devtoberfest 2026 on two additions to draft handling in RAP: collaborative draft, where two users work on the same draft instance and a field is locked only while the other is in it, and draft scope, where editing an instance of one draft-enabled business object puts the related instances of a dependent one into draft as well. Andre Fischer shows what each costs in the behaviour definition and projection, the draft query view and its DCL that collaborative draft needs over a table-based business object, and the CDS table entities that remove both the draft query view and the persistence table, with their current restrictions in ABAP analytics and extensibility; the from-scratch generator in ADT grows a checkbox for them. Both demos run against the DMO flight scenario of SAP-samples/abap-platform-refscen-flight, and the last part hides the draft-related features of an OData V4 app in its manifest, which the session gives as the reason a simple create-update-delete app no longer needs a V2 service binding.published 2026-09-21

From SEO to MEO: Designing Joule-Ready API Layers for SAP Commerce CloudFrom SEO to MEO: Designing Joule-Ready API Layers for SAP Commerce CloudProposes 'Machine Experience Optimization' (MEO), the author's own term and explicitly not an SAP one, for a governed intent facade in front of SAP Commerce Cloud's OCC APIs so an assistant or a SAP Joule skill gets small, business-oriented operations instead of raw endpoints. Works through a full OpenAPI 3.0.3 contract for a product-search intent, with explicit read/write separation, a short-lived confirmation step and an idempotency key for the consequential 'place order' operation, and authorization checked against account and base-site boundaries rather than at the URL alone. The facade still delegates to Commerce's own services, facades and validation; it does not replace or bypass them.BhardwajAditya, published 2026-09-15

It covers importing an OpenAPI 3.0 specification so each operationId becomes a discoverable tool, selecting tools/resources/prompts, and wiring two separate OAuth service keys — one read-only credential the HTTPS adapter uses against the monitoring API, another the MCP client uses to reach the deployed endpoint. The server is deliberately read-only and ships with no rate limiting or audit logging, which the author flags as missing before any write operation or production use.Daggolu_PremSai, published 2026-07-17

A solution advisor and an enterprise architect point Joule Desktop extensions at MCP servers built on API Management inside SAP Integration Suite, and ask it for business partners, orders and line items from an S/4HANA demo system; asked for the ten largest customers it answers from a sample of 200 orders rather than reading the whole table. They then open the API proxy behind it, where a spike arrest policy caps the backend at ten calls per second and the MCP server is configured to expose only the GET resources of the business-partner API so that an agent cannot create one, which is where the edges to Serve your application over MCP and Rate limiting hold. For totals across all sales orders they send the agent to SAP Business Data Cloud instead of the transactional system, since it aggregates and is read-only, and back through Integration Suite for writes such as journal entries.SAP Developers, published 2026-09-30

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

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.

It names an AI Golden Path built on the SAP Cloud Application Programming Model, the ABAP Cloud development model with RAP and the SAP Fiori design system, and a managed agent runtime on SAP BTP that is designed to provide software development kits for building agents in any framework, an agent sandbox, container-hosted execution, a skills registry and continuous evaluations, which is the ground agent tooling covers. Agents are extended without changing their code through four patterns, the first of them tool extensibility through the Model Context Protocol, the concern MCP servers is named for; the process-layer chapter adds that a pro-code path with a standardised agent SDK and a prompt-driven path through the Joule Studio solution produce the same code artifact on the same runtime.

Works one request — create a customer — through eight endpoint-shaped tools, where the agent carries ids between calls and rebuilds the business rules each run, then through a single intent-shaped create_customer that hides the sequence; and says what separates the two: a business operation for a name, parameters a caller can supply without a lookup, the rules in the server rather than the prompt, and a description written for an agent choosing a tool. The SAP Integration Suite half is short — three creation paths, an iFlow behind the API artifact when a tool has to cross systems — and it closes on a checklist to run before publishing.published 2026-07-07

CAP in the age of AI #1 - the MCP adapterCAP in the age of AI #1 - the MCP adapterThe episode that opens the series and the first pass over @cap-js/mcp, with four of the people building it on the call. Two of the adapter's tools are worked through: describe, the one an MCP client reaches for first to get the overview of what it may do, and query, which the panel establishes as read-only. It also writes the server entry into a local agent's own configuration file, which episode three comes back to as auto-wiring.published 2026-08-07
CAP in the age of AI #2 - more on the MCP adapterCAP in the age of AI #2 - more on the MCP adapterWhat the query tool costs in tokens, and the third tool @cap-js/mcp registers. Counted against a model running locally under llama.cpp, the same query is 26 tokens as CQL and 173 as CQN, and the tool definition sent with every system prompt drops from around 5,500 tokens to around 600 — the reason CQL became the default format. The call tool then exposes a service's unbound actions and functions, as one generic tool or, behind a flag, one tool per action with its own description and input schema; a question from the chat about extension points gets the answer that the adapter does the tools, which the panel calls a small subset of the protocol.published 2026-08-14
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 #5 - agents wrap-upCAP in the age of AI #5 - agents wrap-upThe agents topic closed out on what sits around the agent rather than inside it, now that the documentation has moved into capire. The chat preview's session is persisted in the database rather than kept in memory, traces go out through @cap-js/telemetry to a self-hosted MLflow under the OpenTelemetry conventions for generative AI, and the panel is explicit that @agent reuses the MCP adapter's code programmatically without serving an MCP endpoint. It ends in the xtravels sample, where a travel agent delegates to a hotel-service sub-agent and reaches a separately started flight service over MCP through the service binding CAP resolves anyway. Earlier in the hour the same agent answers from a model running on the presenter's laptop, reached as an OpenAI-compatible endpoint.published 2026-10-02
CAP in the age of AI #7 - vector embeddings wrap-upCAP in the age of AI #7 - vector embeddings wrap-upThe same embeddings model taken from SQLite to SAP HANA Cloud, then handed to an agent. Locally it is @cap-js/ai that adds the vector functions SQLite lacks and downloads an all-MiniLM L6v2 ONNX model on first start; on HANA natural language processing has to be switched on, the model name is a mandatory argument, the vectors it returns are 768 dimensions, and dimensions must match on both sides of a comparison. 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
CAP-level Data FederationCAP-level Data FederationA Devtoberfest 2026 session (CAP-31) on letting one CAP application read another's data as if it were local. The modelling half is the same for both answers, which is why the two technical edges hold: the provider defines an API service and exports it with CDS export as an npm package carrying the model, mock data and translated texts, the consumer imports it and puts consumption views on top, and only then is it wired either as service-level replication that copies the rows into local tables each time the server starts, or over the SAP HANA synonyms that cds-federation-synonyms generates, with HDI grants on the provider side and a service replacement that redirects each synonym from its mock table to the provider's container. It is worked through on xflights and xtravels, including the local run where CDS watch mocks the imported service from the CSV files inside the package.SAP Developers, published 2026-10-02
CAP: The Road Ahead - Simplicity in an AI EraCAP: The Road Ahead - Simplicity in an AI EraDevtoberfest 2026 session CAP10, from the head of SAP's Cloud Application Programming Model: forty minutes of live building rather than slides, on the argument that the cheapest code in an AI project is code nobody has to generate. Claude Code builds an invoice-matching workspace from cds init onwards, and each step is one the framework answers rather than the agent: a 42-line domain model that @sap/cds serves as OData and Fiori elements with a status flow, data privacy and change-tracking annotations that produce audit log entries in the console and would reach the SAP Audit Log service once deployed, an imported S/4HANA supplier data product, and semantic matching from a local embedding model after @cap-js/ai is added. The last three steps are annotations: @mcp beside @odata turns the service into an MCP server that a second Claude session queries through @cap-js/mcp, an agent annotation adds the A2A protocol with an agent card and an audit log entry for the agent task, and a skill file gives the agent the matching policy.SAP Developers, published 2026-09-25
Connecting a Custom MCP Server to Joule Work Desktop: A Seamless and Secure Authentication FlowConnecting a Custom MCP Server to Joule Work Desktop: A Seamless and Secure Authentication FlowWalks through connecting a custom MCP server to Joule Work Desktop: a Dynamic Client Registration handshake (RFC 7591) followed by an Authorization Code + PKCE flow through the organisation's SSO via XSUAA or IAS, so authentication establishes the human identity that Joule then attaches to every subsequent tool call. That forwarded identity lets the BTP backend apply its existing authorization checks and row-level data filtering instead of a second permission model, and a role change in XSUAA revokes access on the next token refresh.published 2026-08-17

The demo turns an HTTP endpoint and its OpenAPI specification into MCP tools on the integration cell runtime, does the same on top of an existing API-centric integration, and shows the policies tab where authentication through an external provider, quotas, spike arrest and IP filtering sit, plus the trace of the JSON-RPC calls in monitoring and the agent they are earmarked against in analytics.

Governance at Scale: Why a Clean Core Is What Makes Agent Governance EnforceableGovernance at Scale: Why a Clean Core Is What Makes Agent Governance EnforceableClosing a six-part clean-core series, the post argues that SAP's two agentic-AI governance mechanisms only work against a documented tool surface: MCP Gateway in SAP Integration Suite auto-translates API specifications into MCP tool schemas augmented with natural-language semantics, carrying forward existing authentication, authorization and rate limiting into the agentic layer, while AI Agent Hub, built on SAP LeanIX, discovers and runs verification assessments on agents, LLMs and MCP servers before the resulting badge is read by Joule Studio or SAP Integration Suite to decide what is trusted. Its argument holds the mechanisms up against an undocumented internal interface, where the auto-generated schema and the verification badge have nothing real underneath them, and against a consolidated CAP service exposing only released APIs, where both do.DEEPA_DORAIRAJ, published 2026-09-21
HANA AI Toolkit — Local MCP ServerHANA AI Toolkit — Local MCP ServerAn MCP server that turns the hana-ml Python library into governed tools an agent can call against a HANA Cloud instance, shipped in the hana-ai toolkit and exposed over stdio, SSE and streamable HTTP. Its one firm rule is attributable execution: an audit module writes the MCP-side identity — agent, model, session, tool, redacted arguments — into the HANA connection before any SQL runs, and fails the call if that write fails. A worked example of governance on an MCP tool surface, from SAP's data side rather than CAP's.published 2026-06-15

It covers importing an OpenAPI 3.0 specification so each operationId becomes a discoverable tool, selecting tools/resources/prompts, and wiring two separate OAuth service keys — one read-only credential the HTTPS adapter uses against the monitoring API, another the MCP client uses to reach the deployed endpoint. The server is deliberately read-only and ships with no rate limiting or audit logging, which the author flags as missing before any write operation or production use.Daggolu_PremSai, published 2026-07-17

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

The demo creates an MCP server in a design package from an API already deployed on the tenant, exposes two of its 300-odd resources as tools, attaches authentication and quota policies on a policies tab, and publishes the deployed endpoint as an AI product in Developer Hub of API Management, where an agent subscribes and receives a token, URL, key and secret; the calls then show up in monitoring, in message processing logs and in the analytics dashboard, which is the MCP exposure and the tool governance the edges rest on. Three AI features inside Cloud Integration follow: a content migration agent that converts a PI/PO Java mapping into a Groovy script and generates a second integration flow for its lookup, memory profiling during a flow simulation, and root-cause analysis on a failed message processing log.SAP Developers, published 2026-10-07
RFC/BAPIs Meet AI Agents: Why SAP Integration Suite MCP Server MattersRFC/BAPIs Meet AI Agents: Why SAP Integration Suite MCP Server MattersExplains that SAP Integration Suite's MCP Server artifact can expose RFC-enabled BAPIs, alongside API artifacts and HTTP endpoints, as MCP tools — letting BAPIs on SAP ECC or on-premise S/4HANA participate in agentic workflows without rewriting business logic or waiting for a full ERP transformation. Frames RFC support as a bridge for organisations still modernising rather than a recommendation to build new RFC-based integrations, and notes the exposed BAPIs inherit the server's existing authentication, rate limiting and IP filtering. A demo built against an SAP ECC backend shows an MCP client discovering and invoking several read-only BAPIs from natural-language prompts, with no custom wrapper code.arunmaarirajha_kv, published 2026-07-28
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
SAP Integration Suite + MCP: A Practical Architecture for AI Agents and SAPSAP Integration Suite + MCP: A Practical Architecture for AI Agents and SAPLays out the runtime chain for exposing S/4HANA APIs to an AI agent through SAP Integration Suite: the agent calls a tool on the MCP Gateway, which is built from a governed API Artifact, which still runs on Cloud Integration for mapping, routing and error handling before reaching the backend. It states that the API-artifact approach requires the Integration Cell runtime rather than the normal CPI message-processing runtime, an OAuth-secured REST or OData artifact on OpenAPI 3.0.0-3.0.3, and an entitlement that is service-plan dependent (citing SAP Note 2903776) — so the architecture question is whether the landscape already has the right MCP entitlement, runtime and API foundation.aayushaggarwal, published 2026-09-02

The CAP half starts with two agents scraping a Fiori elements app with Playwright and browser dev tools, then annotates the catalogue service with the MCP protocol through @cap-js/mcp, after which the agent calls the generated describe tool instead of parsing pages. The UI5 half registers a search-authors tool on the browser's model context API inside the same app, with the cross-origin isolation header the API requires, and lists it through the WebMCP Chrome extension — the agent run against it ends on an exhausted Gemini key rather than a result.published 2026-10-16
SAP's API Policy on AI Agents: What It Prohibits, Allows, and Leaves OpenSAP's API Policy on AI Agents: What It Prohibits, Allows, and Leaves OpenReading SAP's API Policy v.4.2026a and its FAQ against the reference architectures, the piece narrows the widely repeated claim that SAP bans AI to what Section 2.2.2 actually restricts: an agent planning and chaining API calls outside an SAP-endorsed route, closed off further by Section 3's block on bypassing API Controls through custom code. 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

In the samples the model selects the tool and does not generate the interface, the prebuilt kind of generative UI, and the subject is the server side of MCP servers: register the resource, link it from the tool's _meta.ui.resourceUri, return text content as a fallback beside structuredContent, call callServerTool() only for tools of the server that owns the app, and send a message to the host when another server such as ARC-1 has to act.

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

050: Clean Core Measurement (Preview)050: Clean Core Measurement (Preview)Walks through Clean Core Measurement (CCM), an open-source tool for tracking ABAP Cloud readiness across a system landscape: a dashboard showing Cloud Ready and Upgrade Stable status and a Technical Debt Score per system, runs recorded under administration, and a process area where custom APIs not released by SAP can be documented and excluded from the score. Reporting breaks the score down to individual objects, the unreleased APIs behind them, and which team or product cluster carries the most outstanding work.Björn S., published 2026-08-03
ABAP development under the Clean Core paradigm: From BAPIs to BO and CDSABAP development under the Clean Core paradigm: From BAPIs to BO and CDSSAP's Level Based Clean Core classification (2025) grades ABAP APIs A through D by cloud readiness, and this piece uses the S/4HANA Cloudification Repository's own count — of 3,847 BAPI function modules for SAP Cloud ERP Private, only 23 are Level A — to show how much Classic API (Level B) code needs to move to RAP business objects instead. A worked Bank Master example matches each BAPI to its EML statement or ABAP CDS SELECT equivalent, and states when that move is actually required: mandatory once on SAP Public Cloud, optional but advisable on Private Cloud/On-Premise as BAPIs stop gaining new fields.published 2026-05-21
ARC-1 with Joule Studio: Bringing Real ABAP System Context into JouleARC-1 with Joule Studio: Bringing Real ABAP System Context into JouleBrings the same BTP-deployed ARC-1 endpoint into Joule through a Joule Studio, classic edition agent configured with Anthropic Claude Sonnet 4 and two MCP servers, ARC-1 and mcp-sap-docs, for work that starts in SAP where the previous part started in Microsoft 365. 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

CCM - Calculate Key FiguresCCM - Calculate Key FiguresExplains how the Clean Core Measurement (CCM) project turns ABAP Test Cockpit findings into the Technical Debt Score shown on its Clean Core Dashboard: messages from the ABAP_CLEAN_CORE_READINESS check are weighted by severity level (B/C/D) and summed per object, while the object's overall classification follows its highest message level rather than the point total. Covers where the calculation can be tuned — configurable weights, an exemption process, and additional metrics for documented but unreleased API use — and how the resulting score and classification drive the object list and per-object processing views.Björn S., published 2026-08-05
Object Release State in Cloudification Repository Viewer for Clean Core ExtensibilityObject Release State in Cloudification Repository Viewer for Clean Core ExtensibilityWalks through the five release states the Cloudification Repository Viewer assigns to an object — Released, Deprecated, Classic API, Not to be Released, and No API — and what each means for ABAP Cloud readiness: the clean core level it maps to and the ATC check priority it triggers. Explains why the same object can carry two states at once, such as a Classic API that later also becomes Released, and why the check has to be run against the specific release being developed on rather than assumed to hold across releases.PrasanthPadmanabhan, published 2026-03-20
Recommendations for Wrapper Interface DesignRecommendations for Wrapper Interface DesignWalks through designing a wrapper interface that encapsulates a classic BAPI (BAPI_USER_GET_DETAIL) behind a C1-released interface, so the code released for ABAP Cloud stays limited to types and structures ABAP Cloud can actually access. Covers when a non-released SAP structure can still be referenced safely, when it cannot, and how the API_CONSISTENCY and API_COMPATIBILITY ATC checks catch the difference before an upgrade breaks it.kaidehmann, published 2026-06-25

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
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

CAP: The Road Ahead - Simplicity in an AI EraCAP: The Road Ahead - Simplicity in an AI EraDevtoberfest 2026 session CAP10, from the head of SAP's Cloud Application Programming Model: forty minutes of live building rather than slides, on the argument that the cheapest code in an AI project is code nobody has to generate. Claude Code builds an invoice-matching workspace from cds init onwards, and each step is one the framework answers rather than the agent: a 42-line domain model that @sap/cds serves as OData and Fiori elements with a status flow, data privacy and change-tracking annotations that produce audit log entries in the console and would reach the SAP Audit Log service once deployed, an imported S/4HANA supplier data product, and semantic matching from a local embedding model after @cap-js/ai is added. The last three steps are annotations: @mcp beside @odata turns the service into an MCP server that a second Claude session queries through @cap-js/mcp, an agent annotation adds the A2A protocol with an agent card and an audit log entry for the agent task, and a skill file gives the agent the matching policy.SAP Developers, published 2026-09-25

Autonomous Diagnostics on Kyma Unplugged: Goose + LiteLLM + KRO + SAP AI Core in ProductionAutonomous Diagnostics on Kyma Unplugged: Goose + LiteLLM + KRO + SAP AI Core in ProductionAn in-cluster autonomous diagnostic pipeline on Kyma Unplugged (open-source Kyma, noted to also run on SAP BTP, Kyma runtime): a Goose agent with kubectl access calls SAP AI Core through a LiteLLM proxy, and most of the post is about the quirks of that route — drop_params silently swallowing unrecognised parameters and beta headers, streaming that has to be off when tools are attached, and prompt caching that sits on the Orchestration V2 API rather than the foundation-model path the LiteLLM provider hits. A second Node.js proxy reaches that API, and the author reports caching unconfirmed at production scale, which leaves the roughly $0.004 per static run a target rather than a measured figure. Spend metrics reach SAP Cloud Logging over OTLP through Kyma's Telemetry MetricPipeline while the health analysis itself lands in Kubernetes custom resources read in Busola, and the stack is declared as KRO Resource Group Definitions applied with one Terraform command.quovadis, published 2026-07-09

The application developer adds a submit-for-review action to the status flow and opens exactly one surface for custom code: a separate extension service marked as extensible code, holding a no-op validate action and two read-only helper entities, which the host application calls before the status change; nothing else is extensible, because the annotation defaults to false. The extension developer works in a project whose base model came from cds pull, with test data, a server.js and types from @cap-js/cds-typer added so the UI and code completion work, debugs the handler locally and pushes it as an @sap/cds-mtxs extension, after which the next request rejects a travel over the policy limit without a restart — the code having been stored as an annotation in the tenant's model and run in a Rust WebAssembly sandbox with no database connection, whose queries go back to the CAP runtime as CQL strings, which is tenant extensibility extended from fields to logic.published 2026-10-09

Each is written up as a self-contained tutorial in the sample repository rather than inline, so the post is a guide to which of them applies to your landscape.martinfrick, published 2022-11-29
Part 2: Runtime Architecture & Cost efficiency gainsPart 2: Runtime Architecture & Cost efficiency gainsThe technical half of the Kyma Evolution series: why a cluster tuned for CAP multitenancy is not just somewhere to run containers, and where the cost efficiency actually comes from.ChristianWeiss, published 2026-02-04
Testing your CAP HANA Artifacts with jest – including multitenancy, hdbprocedure and hdbviewTesting your CAP HANA Artifacts with jest – including multitenancy, hdbprocedure and hdbviewcds.test covers the service; this covers what is underneath it, where the artifact is an hdbprocedure or an hdbview that CDS never sees. That means a real HDI container, so most of the post is about where to get one and how to give CAP access to it — the tests are the easy part once that is true.Tristan, published 2022-08-30

Setting Up Alerts for SAP Cloud Integration Using SAP Alert Notification ServiceSetting Up Alerts for SAP Cloud Integration Using SAP Alert Notification ServiceWalks through wiring SAP Alert Notification service for SAP BTP to a Cloud Integration tenant: creating the service instance and its OAuth2 service key, adding an email action and a subscription on the CPIIntegrationFlowExecutionFailure event, then deploying SAP's standard alert-notification iflow, which polls the Message Processing Logs API for failures. The author tests the setup by deploying a deliberately failing iflow and confirming the alert email arrives.Nikhil_Gursal, published 2026-03-05
Simplifying ABAP Proxy Migration: From SAP PO to Integration Suite (No MDR Required)Simplifying ABAP Proxy Migration: From SAP PO to Integration Suite (No MDR Required)A migration walkthrough for moving ABAP proxy scenarios, both outbound and inbound, from SAP PO to SAP Integration Suite without introducing MDR or a full pipeline redesign. It repoints the SAP_PROXY_ESR RFC destination from the PO Enterprise Repository to the Integration Suite tenant so SPROXY reads Service Interfaces straight from Cloud Integration design packages, and routes inbound calls through SAP Cloud Connector to the ABAP system's /sap/xi/engine endpoint.naveen_kanagaraj, published 2026-04-29
Autonomous Diagnostics on Kyma Unplugged: Goose + LiteLLM + KRO + SAP AI Core in ProductionAutonomous Diagnostics on Kyma Unplugged: Goose + LiteLLM + KRO + SAP AI Core in ProductionAn in-cluster autonomous diagnostic pipeline on Kyma Unplugged (open-source Kyma, noted to also run on SAP BTP, Kyma runtime): a Goose agent with kubectl access calls SAP AI Core through a LiteLLM proxy, and most of the post is about the quirks of that route — drop_params silently swallowing unrecognised parameters and beta headers, streaming that has to be off when tools are attached, and prompt caching that sits on the Orchestration V2 API rather than the foundation-model path the LiteLLM provider hits. A second Node.js proxy reaches that API, and the author reports caching unconfirmed at production scale, which leaves the roughly $0.004 per static run a target rather than a measured figure. Spend metrics reach SAP Cloud Logging over OTLP through Kyma's Telemetry MetricPipeline while the health analysis itself lands in Kubernetes custom resources read in Busola, and the stack is declared as KRO Resource Group Definitions applied with one Terraform command.quovadis, published 2026-07-09
CAP in the age of AI #5 - agents wrap-upCAP in the age of AI #5 - agents wrap-upThe agents topic closed out on what sits around the agent rather than inside it, now that the documentation has moved into capire. The chat preview's session is persisted in the database rather than kept in memory, traces go out through @cap-js/telemetry to a self-hosted MLflow under the OpenTelemetry conventions for generative AI, and the panel is explicit that @agent reuses the MCP adapter's code programmatically without serving an MCP endpoint. It ends in the xtravels sample, where a travel agent delegates to a hotel-service sub-agent and reaches a separately started flight service over MCP through the service binding CAP resolves anyway. Earlier in the hour the same agent answers from a model running on the presenter's laptop, reached as an OpenAI-compatible endpoint.published 2026-10-02
S/4HANA Observability: Streaming SAP Cloud ALM & LogServ Telemetry to BigQuery & Vertex AIS/4HANA Observability: Streaming SAP Cloud ALM & LogServ Telemetry to BigQuery & Vertex AIWalks through pulling SAP Cloud ALM's Outbound Logs, Metrics and Traces APIs — OAuth 2.0 client-credentials auth, protobuf-encoded OTLP payloads, and the guardrails needed against its rate limits and 24 GB/30-day retention baseline — plus SAP LogServ's infrastructure logs, into Google BigQuery for multi-year, cross-domain storage. A time-window SQL join then correlates ABAP exceptions, health metrics, infrastructure events and ITSM tickets, with the joined record passed to Vertex AI (Gemini) to draft a structured incident dossier.Rudrapuneet, published 2026-07-22
