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. Useful as a dated marker of the core moving into ground the community has been covering, and the alpha caveat is the point rather than a footnote.published 2025-10-30
SAP CAP(Cloud Application Programming)开发框架概述SAP CAP(Cloud Application Programming)开发框架概述A Chinese-language walkthrough of CAP built mainly from CAPire's own "About CAP" page: CDS entities, associations, compositions and aspects for data modelling, with an extend Books with @restrict: [{ grant:'WRITE', to:'admin' }] aspect as its authorization example; CQL and CQN queries shown against both a local service and OData's $select/$expand; and the service-and-event model — this.on, this.emit, srv.on — that carries CAP's async processing. It closes with the author's own setup: installing @sap/cds-dk, scaffolding a bookshop project with cds init, and running it with cds watch against local SQLite, mocked authentication and file-based messaging standing in for HANA Cloud, IAS and Kafka.ArthurYang, published 2024-01-07

Connect to Public Cloud API in Node.js via Authorisation CodeConnect to Public Cloud API in Node.js via Authorisation CodeThe authorisation code flow rather than client credentials, which is the harder half: a service key, an XSUAA instance bound to the CAP app, and a destination, with the author saying plainly that this was challenging and they hope it saves somebody the same time.Egan, published 2025-07-22
Consuming data from SAP Datasphere in SAP BTP CAP ApplicationsConsuming data from SAP Datasphere in SAP BTP CAP ApplicationsDatasphere as the source a CAP application reads from — the case for it being that Datasphere already unified the SAP and non-SAP data, so the application does not have to. From a real project.sudheer-tammana, published 2025-06-03
Establishing connectivity between a local CAP runtime and on-premise systemsEstablishing connectivity between a local CAP runtime and on-premise systemsReaching S/4HANA, an on-premise HANA or any HTTP service from a CAP process running on your laptop — the case where the connectivity proxy the platform provides is not there and the tunnel has to be arranged.vLeonkev, published 2025-10-15
Extending SAP Sales and Service Cloud V2 Using CAPExtending SAP Sales and Service Cloud V2 Using CAPAn extension target that does not run on BTP at all — Sales and Service Cloud V2 sits directly on hyperscalers — so the separation between core and extension is enforced rather than encouraged. That constraint is what makes the post worth reading.Quablab, published 2025-07-09
From REST to Datasphere: A CAP-based Integration ApproachFrom REST to Datasphere: A CAP-based Integration ApproachThe reverse direction and a second attempt: the authors had already written data into Datasphere with a small FastAPI service on the OPEN SQL schema, and this is what changed when they rebuilt it on CAP.christian_willi, published 2025-09-30

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
Sending Emails from SAP CAP Applications with Any SMTP ProviderSending Emails from SAP CAP Applications with Any SMTP ProviderWalks through sending mail from a CAP application with no dedicated mail service: create an SMTP destination for a Gmail account in the SAP BTP cockpit, bind it to the Cloud Foundry app, and call the sap-cf-mailer npm package from a CAP service handler naming that destination. The SAP Destination service holds the SMTP host, port and app password so the handler code names only the destination, and the same handler sends plain text, an HTML body, or a message with a base64-encoded attachment.MaheshSirsat1708, published 2025-08-19

Generating PDF on BTP CF using CAP and PuppeteerGenerating PDF on BTP CF using CAP and PuppeteerA headless browser rendering the PDF, which is the answer people reach for when the document is really a web page. The Cloud Foundry part is the difficulty: Puppeteer needs a browser in the buildpack, and that is what the post is actually about.ltomazeli58, published 2024-03-28
How to Generate and Download PDFs on the fly without persisting in CAP ApplicationHow to Generate and Download PDFs on the fly without persisting in CAP ApplicationStreaming a generated document straight to the client without writing it anywhere first — which sidesteps the retention question a stored file creates, and is the distinction worth having beside the attachments capability.HarsithKumarReddy, published 2024-06-18
Event MeshSAP and community
Beginners Guide to Advanced Event MeshBeginners Guide to Advanced Event MeshA scenario-by-scenario walkthrough of Advanced Event Mesh, run through Cloud Integration iFlows: publishing and consuming queue messages, dead message queue setup with retry counts and acknowledgment modes, direct messages, durable topic endpoints and selectors, time-to-live, REST Delivery Points, replay by replication group message ID, parallel consumers with partition keys, and the request-reply pattern. Each scenario is built and verified step by step against a Solace trial account standing in for AEM.PriyankaChak, published 2025-07-24
Complete Guide: Setting Up CAP Plugin for Advanced Event Mesh with OAuth AuthenticationComplete Guide: Setting Up CAP Plugin for Advanced Event Mesh with OAuth AuthenticationWritten because the plugin's own documentation stops short of the prerequisites and the author had to assemble them from three other sources and a help chapter. It joins them: the OIDC application in Identity Authentication, the OAuth profile in Broker Manager, the token checked before anything is wired, and only then the plugin. The author says plainly it came out of trial and error and was going to be a README.rpagni, published 2025-11-10
Event enabling SAP Data Replication Framework with Advanced Event Mesh & AIFAEMEvent enabling SAP Data Replication Framework with Advanced Event Mesh & AIFAEMWalks through connecting SAP's ABAP-side Data Replication Framework to Advanced Event Mesh by way of the AIFAEM add-on, bypassing SAP Cloud Integration: a custom ABAP class maps business-partner replication data into AIF, which publishes it to AEM in CloudEvents format. The author's own disclaimer favours the standard pattern instead — a Standard DRF Replication through an Integration Suite iFlow with the AEM adapter — and presents this direct, custom-ABAP route only as a documented alternative.AlexPfeil, published 2025-08-21
Event-Driven Multi-Tenant Architecture on SAP BTP with CAP and SAP Event MeshEvent-Driven Multi-Tenant Architecture on SAP BTP with CAP and SAP Event MeshThe two topics that are usually written about separately, taken together — because a shared broker is where tenant isolation stops being automatic. It starts from why microservices are decoupled at all, places Event Mesh among the four broker services BTP offers, and then works through what changes when the publisher and the consumer are multitenant.ale_biagi, published 2024-12-19
How to Perform Initial Loads from S/4HANA to Advanced Event Mesh with Odata PollHow to Perform Initial Loads from S/4HANA to Advanced Event Mesh with Odata PollWalks through building a Cloud Integration flow that polls the S/4HANA Business Partner OData API on a timer, splits the response into individual records, and publishes each as an event to Advanced Event Mesh through its adapter, with the topic set dynamically from a grouping property. 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 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
Triggering SAP Build Process Automation Processes from SAP Cloud Application Programming (CAP) AppsTriggering SAP Build Process Automation Processes from SAP Cloud Application Programming (CAP) AppsThe two routes out of a CAP application into a process, side by side: a destination with OAuth2ClientCredentials, the same destination with principal propagation, and Event Mesh with a CloudEvents payload. Written before @cap-js/process existed, so it is the record of what the plugin now does for you — useful when the plugin does not fit, and useful for reading what it is actually doing underneath.ATheobaldt, published 2024-12-09

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
Using Apache Kafka for messaging in the SAP Cloud Application Programming Model (CAP) – Part 2/2Using Apache Kafka for messaging in the SAP Cloud Application Programming Model (CAP) – Part 2/2The practical half: concrete use cases for cds-kafka, running locally and on BTP. It opens by placing the plugin among SAP's own event-driven offerings rather than beside them, which is the part that decides whether you reach for this or for Event Mesh — a comparison a plugin's own README rarely makes about itself.published 2025-01-13
