Use

The SAP Business Connector adapter (BC adapter) enables you to replace one business connector with the Integration Server or the PCK in scenarios where several SAP Business Connectors are used. Guaranteed message delivery is ensured.

The adapter supports the B2B protocol of the SAP Business Connector, which is based on HTTP.

Prerequisites
  • To connect to the Integration Server and the PCK, you need SAP Business Connector 4.7.
  • You can only send RFC-XML documents and IDoc-XML documents with the SAP Business Connector adapter.
    • Between the SAP Business Connector adapter and the SAP Business Connector, documents of type RFC-XML with envelope are supported. This kind of document is supported directly by the SAP Business Connector standard pipeline service for RFC.
    • Between the adapter and the Integration Server/PCK, documents of type RFC-XML (without envelope) are supported, as generated by the RFC adapter or SAP JCo.
  • Calls are stateless and sessions are not supported. There is no transactional context for more than one call.
  • The adapter cannot process or forward attachments. They will be ignored.
  • Multipart/MIME is not supported.
  • The receiver adapter supports quality of services BE and EO, when an RFC-XML document exists as payload of the XI message. Messages with quality of service BE are mapped to a synchronous RFC call (sRFC); messages with quality of service EO are mapped to a transactional RFC call (tRFC).

    If an IDoc-XML document exists as the payload of the XI message, the receiver adapter only supports quality of service EO.

    The sender adapter behaves in the same way as the receiver adapter in terms of quality of service.

  • Quality of service EOIO is not supported.
  • If an IDoc-XML document is sent to the receiver adapter, the XI message header is not evaluated for party conversion. The XI message payload is sent directly to the receiving SAP Business Connector. The message must therefore contain the correct IDoc-XML document, including the IDoc control record.
  • The sender adapter determines the uniqueness of an IDoc-XML document by means of the transaction ID (TID) used. It is transferred by the SAP Business Connector in the HTTP header. The DOCNUM field from the IDoc control record is ignored. There is therefore no connection between the XI message and the DOCNUM field in the IDoc control record.
  • You must configure the Adapter Engine/PCK in the SAP Business Connector to be connected.

Procedure
  1. Create a communication channel in the Integration Directory or in the PCK.
  2. To configure the adapter, choose the Parameters tab page.
  3. Select 
    BC
    as the Adapter Type.
  4. Define the adapter.

    The parameters that you have to enter for the adapter depend on the Direction you want the adapter to have (sender/receiver).
