Limitations of RFC Adapter XI 3.0

In this presentation ( page 20), the following limitations are listed for the RFC Adapter for XI 2.0:


Synchronous RFC

No support forRFMsthat use update task without COMMIT WORK


No callbacks

No session handling

No RFCs to non-SAP systems (using RFC client or server libraries)

tRFC: Support for exactly-once delivery for one message/call

Not all tRFC functionality

No „bundling“ of multiple calls

With version 3.0, what are the current limitations??

    SAP Documentation states the following:


    Note the following restrictions:

    · Assignment is only guaranteed for transactional RFCs (tRFCs), that is, for messages with quality of service Exactly Once (EO).

    · There is no transactional context for more than one RFC call for each LUW (Logical Unit of Work).

    · Not provided: SAPGUI, callbacks, and qRFC (quality of service Exactly Once In Order (EOIO)).

    · RFC library clients (RFC SDK) are not supported.

    · The context in the called system is not kept open over multiple calls (calls are stateless; there is no session).

    · Only the payload of a received message is evaluated. Additional attachments are ignored and not forwarded.

    · The receiver adapter can only process valid RFC XML documents, for example, those generated by the sender adapter or by the SAP JCo.
