How to Build Application Jobs in SAP Business AI Platform, ABAP environmentpublishedA 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 environmentSAP BTP ABAP environmentSAP's ABAP runtime on BTP: ABAP systems developed in the ABAP Cloud model on SAP HANA Cloud, for cloud apps, OData services and side-by-side extensions of SAP S/4HANA.sap official, btp.Async processing
S/4HANA Custom Development - What happens in case of errors in BAPIs or RAP BOs?publishedA Devtoberfest 2026 session on what a custom S/4HANA process does when a BAPI or a RAP business object fails.

CAP in the age of AI #3 - from MCP to A2ApublishedThe episode that finishes @cap-js/mcp@cap-js/mcpA CAP plugin that serves an @mcp-annotated service over MCP with three generated tools, describe, query and call_action, and writes its endpoint into the local agent's configuration in development.sap official, cap 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@cap-js/agentsSAP's own CDS plugin for building agents inside a CAP service, wired to audit logging and telemetry through peer dependencies rather than leaving observability to the author.sap official, cap, which serves it over A2A with an agent card and a chat preview, runs first against a mocked response and then against SAP AI CoreSAP AI CoreSAP's AI service on BTP: the runtime for AI assets, and through the Generative AI Hub inside it the access to foundation models, the orchestration service with its templating, masking, filtering and grounding modules, the Prompt Registry and Document Grounding.sap official, btp bound with cds bind and a hybrid profile, and reuses the MCP adapter's tools rather than defining new ones.Serve your application over MCPSat 17

Async processingcoverage by flavor revisedABAP-PRC is the first option here to state ABAP Cloud: its README says the framework core is written in ABAP for Cloud Development on released APIs, and it runs its steps through the background processing framework or as application jobs. The paragraph on SAP's own mechanisms is unchanged and keeps its 2026-09-14 assessment date; no survey of the other providers was made. Its README lists SAP BTP ABAP Environment and S/4HANA Cloud Public Edition as coming soon, and its Fiori apps are classic BSP objects.Async processing

Merge multiple PDF forms into a single document for download or printing.publishedFaced with bundling several Adobe-Forms-generated PDFs into one file, where FP_JOB_OPEN could not handle the parameters a bundled FP_GET_PDF_TABLE output needed and the forms themselves could not be changed, the author merges the individual PDFs at runtime with the CL_RSPO_PDF_MERGE class instead. Walks through opening the spool job with FP_JOB_OPEN, generating each form via its FP_FUNCTION_MODULE_NAME-resolved function module, adding each result's xstring to the merger with add_document, then calling merge_documents and converting the result for GUI_DOWNLOAD or printing.Document output

ABAP code to wait for the end of "inbound bgRFC type Q" unitspublishedWalks through inbound bgRFC type Q — ABAP's queue-based flavor of async processingAsync processingDoing work outside the request that triggered it, with a guarantee that it eventually happens — deferred jobs, retries, and periodic work.

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.Async processingConfiguring SAP Cloud Integration for an IBP to S/4HANA (on prem / private cloud) integrationpublishedWalks through creating the two BTP destinations an Cloud IntegrationCloud IntegrationBuilds and runs integration flows that process, route and map messages between cloud and on-premise systems, SAP and non-SAP, through prebuilt adapters; available only under an SAP Integration Suite plan.sap official, btp iflow needs for an IBP-to-S/4HANA integration: one of type RFC with a WebSocket RFC server host and port for the IBP tenant, and one of type RFC with the on-premise proxy type, a Cloud ConnectorCloud ConnectorSAP's on-premises agent that links SAP BTP applications to systems in a customer's own network, as a reverse invoke proxy that exposes only the systems and resources it is configured to allow.sap official, btp location ID and a virtual host for the S/4HANA system.

OData Deep Insert: Implementation and Real-Life ExamplespublishedWalks through implementing ODataODataExposing data and operations through OData, including the service model, metadata and protocol versions clients require. Version differences affect which clients can consume a service and which query features they can use.SAP and community, narrow by design Deep Insert on classic SAP Gateway: two entity types joined by an association in SEGW, and a redefined CREATE_DEEP_ENTITY method in the DPC_EXT class that unpacks the header and item payload and calls BAPI_SALESORDER_CREATEFROMDAT2 to create a sales order with its line items in one request instead of separate calls per item. Gives a sample JSON payload to test with Postman or /IWFND/GW_CLIENT and names the usual failure points — an unmapped association, a method that was never redefined, or a commit left out after the BAPI call.OData

A method to create an Adobe form attachment for a work item using the class concept.publishedWalks through an ABAP workflow class, ZCL_WF_PDF, whose methods call an Adobe form through a Form-Builder-generated function module, convert the returned PDF between hexadecimal string and binary with SCMS_XSTRING_TO_BINARY and SCMS_BINARY_TO_XSTRING, and attach it to a work item via SAP_WAPI_ATTACHMENT_ADD and SAP_WAPI_WRITE_CONTAINER, with the class, background-task and SWDD workflow steps shown in full.

Enhancing SAP Business Events with Custom Payload Fields using RAPpublishedWalks through enriching an outbound Business Partner event for Event MeshEvent MeshManaged queues and topics over AMQP, MQTT and a REST gateway, and the bus SAP's own applications publish their business events to.sap official, btp that by default carries only the partner ID: a derived RAP business event, raised from a behaviour definition with RAISE ENTITY EVENT and bound through SWE2 event linkage to a receiver function module, adds first and last name to the payload. The custom event is defined on a root view entity over BUT000 and verified in /IWXBE/EVENT_MONITOR, where the enriched JSON payload shows the extra fields reaching subscribers without an additional callback to the source system.Event Mesh
Invoking Business Agent Foundation Agents from ABAP: A Step-by-Step GuidepublishedWalks through calling a Business Agent Foundation agent's chat endpoint from an on-premise ABAP report: an OAuth 2.0 client profile configured in SE80/SOAUTH2_CLIENT with client-credentials grant against the service key, an HTTP (type G) RFC destinationRFC connectivityCalling ABAP function modules from outside the system over RFC, with destinations and connection pooling handled rather than hand-wired on the calling side.SAP and community, narrow by design in SM59 bound to that profile, and an ABAP report using
CL_HTTP_CLIENT=>CREATE_BY_DESTINATION to POST a JSON message to the agent's sendMessage endpoint and extract the reply by splitting the response string. The destination and client code are the same shape as any outbound REST call from ABAP; nothing here is specific to the agent service beyond the request body and URL.HTTP clientsPattern Function for RFCpublishedA custom ABAP Editor pattern, defined once under SE38 > Utilities > More Utilities > Edit Pattern as Z_RFC_FUNCTION, that generates a CALL FUNCTION ... DESTINATION block for a chosen remote-enabled function module: an EDITOR_EXIT function on the calling system reaches the target system over RFC to fetch that function's generated source, then inserts the DESTINATION clause before handing the pattern back to the editor. It automates writing the RFC call itself rather than explaining RFC destinations as a concept, and the destination name in the sample is hardcoded to the author's own system.RFC connectivity

Using Communication Targets for Outbound RFC Communication in ABAPpublishedWalks through calling a remote-enabled ABAP function module through a communication target instead of a direct RFC destination: on-premise, the APPLDEST transaction creates an application destination (client, CPIC type, host from SM51, authentication); in the cloud, saving a communication arrangement for an outbound-RFC communication scenario creates one automatically. ABAP code reaches the function with
CALL FUNCTION (...) IN REMOTE SESSION, naming the application_destination parameter when a communication target has more than one assigned destination, and the piece walks a worked call to RFC_SYSTEM_INFO.RFC connectivityThu 1
