In QUEUE RFC call if we skip the part ‘AS SEPARATE UNIT’ then all the RFC calls of all the QUEUEs are put into a single LUW upto the point when first Commit Work statement occurs.
Step1. Here we have a program that uses a single queue and inside that we have two RFC FM calls and at last commit work happens so it creates a single TID- Transaction ID ( one luw) . Execute the program.
Step3. Source system: Tx- SMQR( out bound scheduler) – One TID(one luw) fro two RFC FM calls in a single out bound queue.
Step4. Target System: Tx- SMQS[inbound scheduler] – One TID ( one luw) for both FM calls.
See next post where multiple calls Multiple queues are put into a single LUW.
