Modernizing RFC/BAPI-based Integrations for a Clean Core with SAP Integration Suite
Walks a BAPI-based interface from SAP PO through three paths to SAP Integration SuiteSAP Integration SuiteSAP's integration service on BTP: Cloud Integration for orchestration, API Management in front of it, and an MCP gateway that serves a managed API to agents.sap official, btp: lift-and-shift, which keeps the RFC connection to the ABAP system as-is and calls it through Integration Suite's RFC adapter; protocol modernization, which re-exposes the same BAPI as a SOAP web service; and clean core modernization, which replaces it with an SAP-managed API surfaced by the migration assessment report. Follows a BAPI_MATERIAL_AVAILABILITY interface through the first and third paths, showing the generated RFC-adapter iFlow against the OData API found for it.

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
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
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
Using RFC Function Modules and BAPIs in SAP Build Process AutomationUsing RFC Function Modules and BAPIs in SAP Build Process AutomationWalks through calling an S/4HANA BAPI (BAPI_BILLINGDOC_CREATEMULTIPLE, to create a billing document) from an SAP Build Process Automation action: mapping the virtual host to the internal system in SAP Cloud Connector over the RFC protocol and exposing the needed function modules, then creating an RFC-type destination in the BTP cockpit with the virtual message server and SMLG logon group. Once those two are in place, SAP Build lists the exposed BAPIs and RFCs for use in an action.MrRaj, published 2026-07-09
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
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
Claude ported ABAP functions to new APIClaude ported ABAP functions to new APIA first-person account of using Claude Code, driven through the sapcli command line, to install and repair RFC function modules that let a CI pipeline control abapGit and gCTS remotely, rather than treating git as a way to read ABAP source. Instead of trusting a local checkout, Claude read the abapGit login manager class and queried the target system's own type catalogue through sapcli, then used what it found to update a renamed API method and swap a TABLES parameter's structure for the table type BAPIRET2_T.jakub_filak, published 2026-03-16
Extract Rev-Trac requests by custom program and Rev-Trac APIExtract Rev-Trac requests by custom program and Rev-Trac APIA custom ABAP report that does a full-text search across custom long-text fields of Rev-Trac change requests — a search the change-management tool has no built-in feature for — by calling Rev-Trac's own RFC-enabled function modules from a separate connected ABAP system. It walks through the mechanics of RFC connectivity on the ABAP side: looking up the RFC destination at runtime from a system table via a remote-enabled function module, then calling further remote function modules with CALL FUNCTION ... DESTINATION, including the read/update APIs' parameter-naming convention and their commit-on-connection-end behaviour.published 2025-12-30
Pattern Function for RFCPattern Function for RFCA 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.ykaldirim, published 2025-12-02
Using Communication Targets for Outbound RFC Communication in ABAPUsing Communication Targets for Outbound RFC Communication in ABAPWalks 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.Nikolina_MH, published 2025-11-10
IPS provisioning to ABAP Cloud Developer TrialIPS provisioning to ABAP Cloud Developer TrialWalks through provisioning users and groups from SAP Cloud Identity Services' Identity Provisioning into an ABAP Cloud Developer Trial system on Docker, reached through a Cloud Connector and an RFC destination in the BTP subaccount. The author's lessons learned tie the setup to the identity service's own constraints: the subaccount needs a Connectivity Plan and must share the Cloud Identity Service tenant's region, and on the ABAP side an IAS group lands as a Business Role rather than in SUGR, with the Login Name mapped to SU01's user field.Laurence, published 2025-09-04
Configuring SAP Cloud Integration for an IBP to S/4HANA (on prem / private cloud) integrationConfiguring SAP Cloud Integration for an IBP to S/4HANA (on prem / private cloud) integrationWalks through creating the two BTP destinations an Cloud Integration 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 Connector location ID and a virtual host for the S/4HANA system. It then has the reader copy SAP's prebuilt IBP integration packages into the Design workspace and deploy every reusable iflow in them before a business iflow can call the S/4HANA extractor through SAP Connectivity service.SofianePebre, published 2025-08-27
Using SAP managed iFlows for Time series data Integration in SAP IBP – Part 1 - Reading dataUsing SAP managed iFlows for Time series data Integration in SAP IBP – Part 1 - Reading dataWalks through a custom iFlow that reads time-series and master data out of SAP IBP by calling the RFC function modules IBP exposes under communication scenario SAP_COM_0931, reusing SAP's own "SAP IBP – Reusable Integration Flows" package discovered inside SAP Integration Suite and run from SAP Cloud Integration. The call itself goes through an SAP Destination service destination of type RFC — Proxy Type Internet, a communication-user's credentials and jco.client.* properties for host, port and serialization — rather than a connection wired by hand, which is the destination handling RFC connectivity asks for. It also covers the asynchronous read: a UUID transaction id and an offset-driven paging loop for pulling large result sets in packages.Domnic, published 2025-07-18
Using SAP managed iFlows for Time series data Integration in SAP IBP – Part 2 - Writing dataUsing SAP managed iFlows for Time series data Integration in SAP IBP – Part 2 - Writing dataWalks through building a custom integration flow in Cloud Integration that writes time-series and master data into SAP IBP by calling the SAP-managed reusable iFlows behind communication scenario SAP_COM_0931, which consume RFC function modules through a communication user. It details the BTP destination needed to reach them (Type RFC, Proxy Type Internet, and the jco.client.* properties), and the main-flow and local-integration-process design — payload validation in a Groovy script, batch creation, then the XML attributes and payloads for posting master data and key-figure values and for triggering post-processing.Domnic, published 2025-07-18
Consume ABAP RFC Function Modules in CAPConsume ABAP RFC Function Modules in CAPCalling an existing RFC function module from CAP instead of asking somebody to build an OData service for it — which is the actual decision, since the alternative is custom development on the ABAP side for a function that already works.published 2025-03-28
Communicate from a Java Application to ABAP via WebSocket RFC using JCo - Migration GuideCommunicate from a Java Application to ABAP via WebSocket RFC using JCo - Migration GuideWalks a JCo setup from classic CPIC-based RFC to WebSocket RFC: swap the application- or message-server logon properties for jco.client.wshost and jco.client.wsport, and implement DestinationDataProvider's getSSLContext (and, for mTLS, getClientCertificate) since the new connection runs over TLS. It covers building the PKI trust on both sides — a local PKCS12 keystore for the Java side, STRUST's SSL-Server Standard certificate exported and imported for mutual trust on the ABAP side — and notes that on BTP, JCo paired with the Destination service already implements this via the Connectivity service, so the custom SSLContext work can be skipped there.simon_luser, published 2025-01-21
Microsoft Sentinel for SAP goes agentlessMicrosoft Sentinel for SAP goes agentlessExplains how Microsoft Sentinel for SAP's new agentless data connector drops its Docker-based collector agent by reusing an existing SAP Cloud Connector setup together with SAP Integration Suite: on SAP NetWeaver 750 and later, a small set of RFC function modules must be reachable from Integration Suite, added as an RFC connection in the subaccount's Destinations maintenance view, with a user authorised to call them (RFC connectivity). It also covers calling the audit log API remotely, which on older releases needs SAP note 3054326 and a different integration-package configuration.published 2024-12-17
Recommendations for Customers on using the Direct Push-Based IntegrationRecommendations for Customers on using the Direct Push-Based IntegrationExplains SAP's direct push-based integration, where two ABAP systems (SAP BTP ABAP environment, SAP S/4HANA Cloud or SAP S/4HANA on-premise) exchange business events by calling each other over RFC connectivity, carried over CPI-C or WebSocket depending on the release, through a sender channel on one side and a matching receiver channel on the other that lists which events it wants. It recommends the mechanism only between systems in the same location or subaccount, without public exposure, and for prototyping event-driven scenarios before moving to Event Mesh or SAP Integration Suite, Advanced Event Mesh at a larger scale.sandra_thimme, published 2024-08-09
WebSocket RFC to Cloud Using SAP Business ConnectorWebSocket RFC to Cloud Using SAP Business ConnectorWalks through wiring RFC connectivity between an on-premise ABAP system and a cloud ABAP system (SAP S/4HANA Cloud or Steampunk) through SAP Business Connector, which tunnels classic RFC over a WebSocket/HTTPS connection past firewalls. Covers the RFC destination of type T on the source system, the Communication User, Communication Scenario and Communication Arrangement needed on the cloud side to allow-list the function modules being called, and the three configuration steps on the Business Connector itself, closing with a list of common connection errors and their fixes.Ulrich_Schmidt1, published 2022-10-17
How to use SAP Data Intelligence with SAP Cloud ConnectorHow to use SAP Data Intelligence with SAP Cloud ConnectorWalks through reaching an on-premise network from SAP Data Intelligence Cloud with Cloud Connector: installing the client, assigning the Cloud_Connector_Administrator role, registering the subaccount, and mapping on-premise systems as ABAP, HANA or HTTP back-ends in Data Intelligence's Connection Manager. For an ABAP back-end it names the function-module whitelist and the gateway port format RFC access needs, per SAP Note 2835207.Former Member, published 2021-03-16
