Developers implement parallel processing using specific ABAP syntax and standard function modules: CALL FUNCTION ... STARTING NEW TASK ... DESTINATION IN GROUP ... Initiates an asynchronous call to a remote-enabled function module in a separate dialog work process. PERFORMING <subroutine> ON END OF TASK Specifies a callback routine in the main program that executes when the parallel task finishes. RECEIVE RESULTS FROM FUNCTION ... Used within the callback routine to retrieve IMPORT, EXPORT, and TABLE parameters from the completed function module. WAIT UNTIL <logical expression> Suspends the main program until a condition (e.g., all tasks are completed) is met. SPBT_INITIALIZE Optional function module to check the availability of resources and determine the number of free work processes for efficient data packet sizing. Implementation Frameworks For simplifying development, several SAP-provided frameworks are available: Procedural Approach (aRFC based): The classi...
