My CAP Projects ToolboxMy CAP Projects ToolboxA working inventory of daily CAP tooling: scaffolding a project with cds init and growing it facet by facet through cds add (TypeScript, seed data, an .http test file, a handler stub), then running it with cds watch and setting a breakpoint in a custom handler from SAP Business Application Studio's JavaScript Debug Terminal. It also walks through an @open entity that accepts properties the model never declared, and reading temporal data defined with CAP's temporal aspect, where a plain read returns only what is valid now and a custom handler is needed to retrieve every time slice.vvdries, published 2024-12-23
SAP Cloud Application Programming Model（CAP）：カスタムロジックの実装 – Part 2SAP Cloud Application Programming Model（CAP）：カスタムロジックの実装 – Part 2A walkthrough of implementing custom logic in a CAP Node.js service for the capire bookshop sample, registering before, on and after handlers around the generated CRUD service for its Books and Orders entities. The before handler validates an incoming order's amount and runs a transactional CQN UPDATE to decrement stock, raising a 400 or 409 through req.error when the amount is invalid or no rows match; an after handler on READ appends a discount note to overstocked books.rasai, published 2021-01-01
A simple example of a SAP RAP Application based on Legacy API without UUID keysA simple example of a SAP RAP Application based on Legacy API without UUID keysWalks through building a managed RAP business object over the Flight Reference Scenario's Travel and Booking entities with unmanaged save and late numbering, so CRUD operations route through the legacy /DMO/FLIGHT_TRAVEL_CREATE, _UPDATE and _DELETE function modules instead of generated persistence, a worked case of ABAP's transactional model. Covers the ADJUST_NUMBERS and SAVE_MODIFIED saver methods that map preliminary draft keys to the legacy-assigned travel and booking IDs, and a GetDefaultsForBookings action that proposes the next booking ID during draft handling.cseijas, published 2025-09-01
BEHAVIOR_ILLEGAL_STATEMENT dump | Technical workaroundsBEHAVIOR_ILLEGAL_STATEMENT dump | Technical workaroundsThe BEHAVIOR_ILLEGAL_STATEMENT dump fires in SAP RAP when an explicit COMMIT WORK or ROLLBACK WORK, or a direct database write, collides with RAP's own transactional model: a Logical Unit of Work split into an interaction phase, where changes sit in a transactional buffer, and a save sequence that validates and persists them. The post then names four ways to move the offending statement into a separate task instead — the Background Processing Framework, parallel processing, Application Jobs, or, on-premise only, a wrapper RFC function module called with DESTINATION 'NONE' — pointing to further reading for each rather than working through any of them here.PranayGaroo, published 2025-08-11
BO Interface APIs : An alternative to BAPIs and traditional FMsBO Interface APIs : An alternative to BAPIs and traditional FMsWalks through updating an S/4HANA Purchase Order's line items through a released BO interface instead of a BAPI, using EML against the underlying CDS entity and a COMMIT ENTITIES statement because the call sits outside a behavior class. Argues the BO interface route avoids a RAP behavior class's restriction against calling COMMIT WORK directly, and covers finding a released interface's CRUD operations on api.sap.com and extending the same approach to a custom field or a custom RAP-based Fiori app's own BO.Sudhan_Nagarajan, published 2025-07-02

Mastering Internal Actions in SAP RAP: Automatic Header Calculation in ABAP CloudMastering Internal Actions in SAP RAP: Automatic Header Calculation in ABAP CloudWalks through a sales-order BDEF where an item-level determination triggers a header-only internal action by EML in local mode, so a quantity or price change recalculates the order total and applies a 10% discount above $10,000 without a UI button or external OData call reaching the logic directly. Argues for an internal action over inline determination code on reusability and separation of concerns: a determination decides when logic runs, the action decides what runs, and marking it internal keeps Fiori Elements and external OData clients from invoking it.sharathtm, published 2026-08-06
ABAP code to wait for the end of "inbound bgRFC type Q" unitsABAP code to wait for the end of "inbound bgRFC type Q" unitsWalks through inbound bgRFC type Q — ABAP's queue-based flavor of async processing built on background remote function calls — and gives a helper ABAP class that polls cl_qrfc_client_inbound for each unit's and queue's state until every unit submitted across a set of parallel qRFC queues has finished. The method assumes no single unit spans more than one inbound queue, and the author flags the classes it relies on, cl_qrfc_client_inbound=>get_unit_state and get_queue_state, as unverified for this use.Sandra_Rossi, published 2025-10-07

Cloud-Native with ABAP Cloud – The Transactional Outbox PatternCloud-Native with ABAP Cloud – The Transactional Outbox PatternImplements the transactional outbox pattern in ABAP Cloud's background processing framework (bgPF): a RAP business object's save sequence registers a bgPF handler implementing IF_BGMC_OP_SINGLE, and the RAP runtime runs it, and only then emits the message, after the database commit succeeds, so a rolled-back transaction emits nothing. The post walks through the full working example published as SAP-samples/abap-platform-rap-transactional-outbox-with-bgpf.published 2025-11-12
DIY JDBC Sender Adapter for SAP Integration SuiteDIY JDBC Sender Adapter for SAP Integration SuiteSimulates the JDBC Sender Adapter that SAP Integration Suite dropped from SAP PO by polling a source database with a Request/Reply step, triggered by a configurable scheduler or a manual HTTP call, and writing the result to a DataStore or JMS Queue to decouple polling from mapping and insertion. Retries run against a configured maximum, a failed batch escalates to a Dead Letter Queue once they are exhausted, and a mapping failure skips retries and escalates straight away from its own local subprocess. The author reports migrating several SAP PO scenarios onto this flow design and offers a reusable template on request.lanza, published 2025-10-21
Event Mesh + AMQP: The Retry Trap Nobody Warns You AboutEvent Mesh + AMQP: The Retry Trap Nobody Warns You AboutWorks through two patterns for retrying failed messages from Event Mesh's AMQP sender adapter on Cloud Integration, whose native retry has no configurable delay or backoff: bridging into a JMS queue for full exponential-backoff control, or looping messages through a dedicated retry queue with a TTL and a Dead Message Queue. Compares both against a Groovy sleep() workaround that blocks the adapter's connection and the runtime's worker thread, and shows that Advanced Event Mesh's own adapter ships configurable retry interval, backoff and broker-side redelivery without either workaround.MateuszPiotrowski, published 2026-03-09
Quick tip: event/task scheduling in CAP Node.js (in alpha state)Quick tip: event/task scheduling in CAP Node.js (in alpha state)A note on something spotted in capire's May 2025 release notes rather than a technique: CAP Node.js is to support scheduling events — actions and functions included — with callbacks, currently alpha and explicitly subject to change.

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.

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

CAP: Consume External Service – Part 3CAP: Consume External Service – Part 3Built to work around CAP limitations at the time — OData-only external services, no custom headers, no complex OData queries — the post walks through cdse, the author's own module that resolves a named destination from the CAP project's configuration and calls axios directly, so a handler reads the same way whether it is tested locally against a raw URL or deployed against SAP Cloud Platform's Destinations service. A 2022 update at the top of the post calls it obsolete, since the CAP framework has since addressed the limitations it set out to work around. The walkthrough of cdse resolving a destination and switching between a local credentials.url and an SCP destination, including pulling credentials from VCAP_SERVICES when the lookup fails locally, still holds as a worked example.published 2020-07-27

Principal Propagation from BTP Web App to S/4HANA via SAP Integration SuitePrincipal Propagation from BTP Web App to S/4HANA via SAP Integration SuiteWalks through configuring principal propagation from a BTP web app, through SAP Integration Suite and Cloud Connector, to an on-premise S/4HANA system, so the backend receives calls as the logged-in user rather than a shared service account. The BTP Destination service uses OAuth2JWTBearer to exchange the user's Cloud Identity Services JWT for an Integration Suite token, and the iFlow's OData V2 receiver adapter reaches S/4HANA through Cloud Connector with Principal Propagation authentication. The Cloud Connector Subject Pattern builds the outbound certificate's CN from the token's user_name claim, which is populated from the IAS email rather than the sub claim, so identity resolution on S/4HANA hinges on that email matching a resolvable logon name.Joni, published 2026-07-10

SAP BTP Destinations in a Nutshell Part 1 - Motivation & NoAuthentication DestinationsSAP BTP Destinations in a Nutshell Part 1 - Motivation & NoAuthentication DestinationsOpens a series on SAP BTP Destinations by walking through the simplest case, a NoAuthentication destination from one CAP Node.js app to another on Cloud Foundry, shown two ways: executeHttpRequest from @sap-cloud-sdk/http-client, and a manual sequence that reads the destination service's credentials from VCAP_SERVICES, fetches an OAuth token, and requests the destination by name before calling its URL. The manual path is written deliberately verbose to show what the Cloud SDK call does behind the scenes; later parts of the series cover the other destination types.JakobFra, published 2023-05-23

Secure Service Consumption Across HyperscalersSecure Service Consumption Across HyperscalersSAP's design for a workload on SAP BTP that calls Amazon Web Services or Google Cloud services with short-lived credentials instead of stored keys, which is the outbound side of authentication: the BTP application proving who it is to another cloud. On AWS it draws two paths, an ID token from Identity Authentication in Cloud Identity Services exchanged through AWS STS for an IAM role, or an X.509 certificate kept in SAP Destination service and presented to IAM Roles Anywhere; on Google Cloud only the token path, through Workload Identity Federation and an impersonated service account. It is drawn for those two hyperscalers only, and Microsoft Azure has no page in it.published 2025-05-14

Event Mesh + AMQP: The Retry Trap Nobody Warns You AboutEvent Mesh + AMQP: The Retry Trap Nobody Warns You AboutWorks through two patterns for retrying failed messages from Event Mesh's AMQP sender adapter on Cloud Integration, whose native retry has no configurable delay or backoff: bridging into a JMS queue for full exponential-backoff control, or looping messages through a dedicated retry queue with a TTL and a Dead Message Queue. Compares both against a Groovy sleep() workaround that blocks the adapter's connection and the runtime's worker thread, and shows that Advanced Event Mesh's own adapter ships configurable retry interval, backoff and broker-side redelivery without either workaround.MateuszPiotrowski, published 2026-03-09

Selects fields and expands associations with $select/$expand against an EDMX from the API Business Hub, and works around the OData V2 adapter's lack of JSON support by falling back to the HTTP adapter with an XML-to-JSON converter. Flags the trade-off: the pattern needs no backend change beyond activating the API, but the polled payload has to stay aligned with whatever event format the ERP pushes on change.AlexPfeil, published 2025-04-04
How to subscribe or fetch data from solace to CPI using AEM Adapter : part-5How to subscribe or fetch data from solace to CPI using AEM Adapter : part-5Closes a series on event-driven architecture with Solace by detailing the subscriber side of an iFlow in Cloud Integration: an advanced event mesh adapter feeds an exception subprocess, and a Groovy step classifies each failure as recoverable, left to Solace's own retry, or non-recoverable, answered with a custom property that tells Solace to stop retrying before the message reaches an escalation layer. The escalation layer names email, ServiceNow and Loggly as destinations without explaining any of them.pavanKolla, published 2025-08-03
How to use a CAP application to manage DMQ messages on SAP Advanced Event MeshHow to use a CAP application to manage DMQ messages on SAP Advanced Event MeshA CAP application built for the failure path rather than the happy one. Messages that land in a Dead Message Queue are deleted for good when their TTL expires, so this pulls them out first and holds them in quarantine, where a Fiori elements UI lets someone inspect a payload, correct it and reinject it. An operations tool, and a rare write-up of what to do after delivery has already failed.stefan-keuker, published 2025-12-31

Implementing Event-Driven Architecture in CAP Java using SAP Event MeshImplementing Event-Driven Architecture in CAP Java using SAP Event MeshPublish and consume from the Java stack, which most of the Event Mesh writing on the community does not cover. The MTA declaration and the credentials come first, then the emit and the handler, then the two sections that make it worth keeping: error handling with retries, and securing the events with OAuth.Soumya-Pirlamarla, published 2025-11-26

Integrating SAP S/4HANA Invoicing with KSeF Using SAP Event Mesh and CAPIntegrating SAP S/4HANA Invoicing with KSeF Using SAP Event Mesh and CAPA concrete regulatory deadline rather than a demo topic: every Polish invoice has to pass through KSeF, the national e-invoice platform, and this proposes the route — S/4HANA business events onto Event Mesh, a CAP application consuming them and talking to KSeF. Short, and offered as an example to argue with.Yahor, published 2024-08-29
Migrating from ASANWEE to ASAAEMEE: From SAP Event Mesh to SAP Advanced Event MeshMigrating from ASANWEE to ASAAEMEE: From SAP Event Mesh to SAP Advanced Event MeshA migration walkthrough for switching an SAP ERP or S/4HANA on-premise system from classic SAP Event Mesh to SAP Advanced Event Mesh: new RFC destinations to the broker's REST, handshake and token endpoints, trusting its certificate, activating the AEM business configuration set, and re-pointing the NetWeaver Add-On for Event Enablement's outbound object and dynamic topic mapping at the new instance. It assumes the Event Add-On for ERP (ASAAEMEE) is already installed and covers only the technical cut-over, not setting up event publishing from scratch.Benedikt_Sprung, published 2026-02-13
Publish events from CAP Node.js applications to Event Mesh of Integration SuitePublish events from CAP Node.js applications to Event Mesh of Integration SuiteThe smallest complete example: cds init, a service with one function, cds.connect.to('messaging') and an emit to a topic. Deliberately scoped — the Event Mesh setup is skipped and the subaccount is assumed to be the same one — so what remains is the handful of lines on the CAP side and the binding that makes them reach the broker.KevinWang_ST_Consultancy, published 2026-02-13

Documents a mismatch between Cloud Foundry's automatic queue provisioning and Event Mesh's management API, worked around by pointing the service key's management URI at a mock endpoint that always returns 201.KevinWang_ST_Consultancy, published 2026-02-13
SAP Advanced Event Mesh – Manage Advance Event Mesh with API’sSAP Advanced Event Mesh – Manage Advance Event Mesh with API’sMaps the API surface of SAP Advanced Event Mesh: the REST API(v2) for administering the cloud environment and its event broker services (with legacy v0/v1 noted as discouraged), SEMP(v2) for provisioning and operating a single event broker, and the open protocols and standards it supports for consuming events, among them JMS, OpenMAMA, REST, AMQP 1.0, MQTT and WebSocket. Covers how each API authenticates — bearer tokens with scoped permissions for REST API(v2), username/password or OAuth2/certificate-based for SEMP(v2) — and where to find the connection details and reference documentation for each.Nils_Lorenz, published 2024-08-28
SAP Codejam on Event Driven Build ProcessSAP Codejam on Event Driven Build ProcessA hands-on CodeJam walkthrough of an event-driven flow: a Business Partner creation event from a simulated S/4HANA Cloud system is published to SAP Advanced Event Mesh, where the author configures topics, queues and subscriptions and forwards it through a REST Delivery Point to SAP Build Process Automation, which runs a business process with a human approval step and an asynchronous callback to a third-party system. The event producer stays unaware of its consumers, with SAP Build acting purely as an orchestrator reacting to events.Sharathmg, published 2026-02-03
SAP EHS Public Cloud: Extending Your Existing Landscape Side-by-Side - Guidebook (Part 4)SAP EHS Public Cloud: Extending Your Existing Landscape Side-by-Side - Guidebook (Part 4)Two custom iFlows in SAP Integration Suite subscribe over AMQP to Event Mesh queues, triggered by SAP S/4HANA On-Premise's Enterprise Event Enablement channels publishing Equipment and Functional Location changes; each flow calls the on-premise OData API, maps the result, and pushes it into SAP S/4HANA Cloud Public Edition through the SAP_COM_0395 communication scenario. The synchronized Plant Maintenance data feeds SAP EHS Public Cloud's risk management, incident management and emissions management processes, which otherwise have no asset master data of their own.duynguyendeloitte, published 2025-11-28
SAP Event Mesh Architecture PatternsSAP Event Mesh Architecture PatternsNine architectural patterns for wiring producers and consumers through queues, topics and webhooks: single-subscriber point-to-point delivery, fan-out to multiple subscribers, filtering several event types into one subscriber, domain-scoped topic subscriptions, an aggregator that bundles related events, a multi-stage enrichment pipeline, scatter-gather over parallel requests, a dead-letter queue for poison messages, and pushing events to an HTTP webhook. Each pattern states its motivation, a pros-and-cons pair, when to use it and example queue or topic names.vbalko-claimate, published 2025-05-16
SAP Event Mesh: S4 HANA On-Prem and SAP CI(BTP IS) through WebSocket and WebhooksSAP Event Mesh: S4 HANA On-Prem and SAP CI(BTP IS) through WebSocket and WebhooksA step-by-step walkthrough of wiring Event Mesh to publish and consume events between an on-premise S/4HANA system and Cloud Integration, contrasting persistent queues (one subscriber, kept until consumed) against unpersisted topics, and WebSocket's AMQP transport against webhook delivery for the same queue. Two tested findings support it: a queue consumer running in continuous consumption mode receives a message ahead of a webhook on the same topic, and a message stays queued and is retried (almost 8770 times in under a minute, in the author's test) until the consumer processes it successfully.FarooqAhmed, published 2023-10-03

Using Apache Kafka for messaging in the SAP Cloud Application Programming Model (CAP) – Part 1/2Using Apache Kafka for messaging in the SAP Cloud Application Programming Model (CAP) – Part 1/2The theory half of a pair introducing cds-kafka: what the plugin is for and what it can do, with event-driven architecture set up as the reason rather than assumed. Nothing is deployed here — the running application is part two — so this is the post to read if the question is whether Kafka belongs in the picture at all rather than how to wire it.published 2025-01-02
