qRFC with Outbound Queue & Inbound Queue between two different SAP systems - One LUW per mixed part of the Queues

---------------------------------------------------------------------------------------------------------------------------------------
Step1. If  one queue contains two RFC FM calls and we have two such Queues, then some part of Each Queue can be put into a single LUW. Execute the program.

--------------------------------------------------------------------------------------------------------------------------------
Step2. Source system: program output.

Step3.  Source system: Tx- SMQR ( out bound scheduler) . Select the Two queues. Double click on it.

Step4.  Source system:  Double click on queue name.

Step5.  Source system:  So here some part of the each queue is added to one LUW. process the queues.

Step6. Target system: :  Tx- SMQS( In bound scheduler) . Select the two queues and double click on it.

Step7.  Target system:  Double click on it.

Step8.  Target system:  So we have two LUWS each contains some part of both queues.

Step9.  Target system:  Juts a comparison of TIDs of the source and target system.
