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

Triggering Background Jobs from RAP Actions – A Practical GuideTriggering Background Jobs from RAP Actions – A Practical GuideWalks through a RAP business object whose Saver Class calls a function module IN BACKGROUND TASK from the save phase, and that function module in turn uses JOB_OPEN, SUBMIT ... VIA JOB and JOB_CLOSE to schedule a classic background job that finishes the long-running work, so the triggering UI transaction stays lightweight. The mechanism shown — an asynchronous function-module call plus a submitted executable report — is Standard ABAP background processing rather than ABAP Cloud's released scheduling APIs.Arshiya2, published 2026-04-15
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
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
Connect SAP CAP (Node.js) to On-Premise/Private PostgreSQL using SAP Cloud ConnectorConnect SAP CAP (Node.js) to On-Premise/Private PostgreSQL using SAP Cloud ConnectorAn end-to-end route from a CAP Node.js application on Cloud Foundry to a PostgreSQL database that is never made publicly reachable, over BTP Connectivity and the Cloud Connector using a TCP destination and SOCKS5. The part worth having is that it covers the deployer as well as the server: the generated PostgreSQL deployer has to reach the same private database to deploy the CDS model, and a guide that only connects the runtime leaves you with a schema you cannot install.Kalaikovan, published 2026-08-07

Implementing Dynamic Subaccount-Based Routing in SAP CAP with SAP BTP DestinationsImplementing Dynamic Subaccount-Based Routing in SAP CAP with SAP BTP DestinationsWhy environment variables are the wrong place for backend endpoints in a CAP application, and what replaces them: cockpit destinations resolved at runtime, with the subaccount or instance identified as the request is handled. The argument is about redeployment — an endpoint kept in the environment means a deploy every time it moves — and the shape it produces is one codebase serving several landscapes without a build per landscape.Dnyaneshwar Salve, published 2026-03-18
No-Code MCP Servers with SAP Integration Suite: From REST API to AI AgentNo-Code MCP Servers with SAP Integration Suite: From REST API to AI AgentWalks through turning a deployed API artifact into a no-code MCP server in SAP Integration Suite's MCP Gateway: the API artifact's OpenAPI spec must be version 3.0.0-3.0.3, since Swagger 2.0 is rejected, and its backend is reached through a BTP Destination using OAuth2ClientCredentials so the agent calling the server never sees the backend secret. The API artifact's own Authorization policy sets an OAuth scope and Trust Upstream MCP Authorization, and the gotcha list traces a 403 on a valid token to that policy rather than to authentication, before the finished MCP server is published through Developer Hub and connected to Claude Code.eddiedu, published 2026-09-15
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

Its central point is that the Kafka offset must be committed only after the pipeline has processed the message successfully, with a worked table of which failure scenarios (missing Confluent magic byte, invalid schema ID, payload over the configured limit) withhold the commit versus let it through, to avoid poison-pill loops and silent message loss.

SAP BTP - CI - Immutable Event Routing per Domain with Metadata-Driven Consumer OrchestrationSAP BTP - CI - Immutable Event Routing per Domain with Metadata-Driven Consumer OrchestrationDescribes a metadata-driven "Smart Router" pattern for Cloud Integration in SAP Integration Suite: one Kafka Sender Adapter per domain reads a wildcard topic, and a single immutable router iFlow resolves single, multiple or both consumers at runtime from Value Mapping entries and a Groovy script, instead of one adapter and iFlow per consumer added. It compares three candidate architectures — a two-layer router/dispatcher split, the recommended single-layer router, and a rejected global cross-domain router — and covers AVRO payload handling through Base64 and an externalized schema parameter, and consolidating the routing logic into one cached Groovy class to limit JVM class-loading overhead. The piece continues the author's earlier immutable Kafka topic routing post and names SAP Event Mesh as one of several broker-agnostic alternatives to the Kafka adapter used here.rhviana, published 2026-05-25
SAP Cloud Integration (CI/CPI) - Reusable Script Collection Pattern for Sensitive Data MaskingSAP Cloud Integration (CI/CPI) - Reusable Script Collection Pattern for Sensitive Data MaskingOpens with the question compliance teams ask about Cloud Integration, whether an integration team based outside Europe with Message Monitoring access can read the personal data in a logged payload, and answers that in most standard configurations it can. The pattern against it is a reusable Groovy script collection plus one global variable holding the masking rules: a script near the start of an iFlow AES-encrypts the original payload into a header or property and replaces values in the body by value pattern first and field-name keyword second, a second script restores the original just before the sender, so a Log Payload step anywhere in the flow captures the masked body while the target system still receives the real data.

For file-based and Kafka sources, SAP Integration Suite iFlows did work a direct connection could not — flattening nested JSON, PGP decryption and orchestrating the SAP Ariba extraction built on SAP's own BTP Procurement Data Extractor content.saikrishna_kalivarapu2, published 2026-08-17
SAP Integration Suite: Intelligent Integration with AI AdapterSAP Integration Suite: Intelligent Integration with AI AdapterThe AI Adapter adds generative AI as a receiver step inside a Cloud Integration flow, connecting through either AICore-GenAIHub — a single API onto SAP AI Core's Generative AI Hub and its foundation models — or Custom-OpenAI-Rest, a plain REST call out to a provider such as OpenAI. SAP Integration Suite starts the call from the iFlow and feeds the model's response into the next step, which is the mechanics behind the sentiment-analysis, summarisation and routing use cases the piece lists without walking through any one of them.meena_choudhary, published 2026-01-28
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

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

Creating an SAP SD Billing Document Using a BAPI in SAP Build and Accessing It Through 'Joule Work'Creating an SAP SD Billing Document Using a BAPI in SAP Build and Accessing It Through 'Joule Work'Walks through the two pieces of connectivity a SAP Build Process Automation action needs to call an on-premise BAPI: mapping the virtual host to the internal S/4HANA host in Cloud Connector over the RFC protocol, and creating an RFC-type destination in the BTP cockpit so BAPI_BILLINGDOC_CREATEMULTIPLE becomes a selectable action. The resulting process creates an SD billing document from a sales document number and is reached through SAP Build Work Zone, including from the Joule Work mobile app.MrRaj, published 2026-06-29
Expose RFCs as MCP Tools in Integration SuiteExpose RFCs as MCP Tools in Integration SuiteWalks through creating an MCP server in SAP Integration Suite from an RFC source: an on-premise RFC destination labelled for Integration Cell inclusion, a search over the backend's function modules (minimum seven characters), and up to 50 selected modules each becoming a tool. Covers the resulting server's configuration (Source, Tools and Prompts, with no Resources section for this source) and the two scopes an RFC-based server's policy adds beyond an API-sourced one, API.invoke and ESBMessaging.send, plus the RFC receiver adapter used at runtime. Demonstrates the flow with a purchase-order scenario where an AI client calls BAPI_PO_CREATE1 and BAPI_PO_GETDETAIL1 as MCP tools.ronit199666, published 2026-09-24
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'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

A Groovy script then calls PartnerDirectoryService.getParameter to read a partner's custom activity parameters and general value-mapping data stored under the agreement, so dynamic field mapping comes from the agreement rather than a flow per partner.

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

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.
