SAP adapter

Bidirectional integration with SAP ECC and SAP S/4HANA. Consumes IDocs pushed from SAP on the Listener side and posts IDocs or invokes BAPI/RFC remote calls on the Caller side.

DIRECTION ↓ ↑ Receive & Send MODES One-way · Two-way AUTHENTICATION SAP Authentication EDITION All editions

The iQBus SAP adapter speaks the two interfaces SAP has stabilised over decades of integration work: IDocs for asynchronous business document exchange, and BAPI/RFC for synchronous remote calls into ABAP. Both directions are covered by a single adapter, paired with an SAP Authentication carrying the system ID, gateway, client number, and user credentials.

Listener side, consume IDocs from SAP

Bound to a receive port, the adapter registers with the SAP gateway as a tRFC destination and waits for IDocs pushed from SAP. Each IDoc is published to the bus as a structured message, ready to be mapped onto the partner format the downstream send port expects.

Caller side, post IDocs or call BAPI/RFC

Bound to a send port, the adapter either posts an IDoc into SAP or invokes a BAPI/RFC function. Two-way mode returns the BAPI response (or the IDoc status) back to the bus so the integration thread can act on it.

Authentication

The SAP adapter pairs with a dedicated SAP Authentication object. The Authentication carries the connection target and credentials in a form specific to SAP.
