ABAP Simple Async Framework

Parallel-processing is implemented with a special variant of asynchonous RFC.

ABAP requirements (see also the online documentation for the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword):

• The function module that you call must be marked as externally callable. This attribute is specified in the Remote function call supported field in the function module definition (transaction SE37)).
• The called function module may not include a function call to the destination "BACK".
• The calling program should not change to a new internal session after making an asynchronous RFC call. That is, you should not use SUBMIT or CALL TRANSACTION in such a report after using CALL FUNCTION STARTING NEW TASK.
• You cannot use the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword to start external programs.

Demo program (with aRFC/pRFC): ZBC_ASYNC_DEMO.
