qRFC with Outbound Queue & Inbound Queue between two different SAP systems - One LUW for Multiple QUEUE Calls

The below post shows how to club multiple QUEUE ( one queue having multiple FM calls) into a single LUW. After calling the TWO queues with their respective FMs , at the end Commit work happens so every thing is put into a single LUW. Execute the program.

COMMIT WORK.
WRITE :/ 'Check outbound queue in source system in Tx- SMQS'.

-----------------------------------------------------------------------------------------------------------------------------

Step1. Source System: Tx- SMQR( out bound scheduler). Select the line and click on the qRFC Monitor button.

Step2. Source System: Select both the out bound queues and double click on it.

Step3. Source System: Double click on it.

Step4. Source System: So here we have a single TID for all the FM calls that  belongs to two different Queues.  process the out bound queue.

Step5. Target System: Tx- SMQS( Inbound Scheduler): Select the line and click on the qRFC monitor button.

Step6. Target System: Select both the inbound queues. Double click on it.

Step7. Target System: Double click on the queue name.

Step8. Target System:: So here we have a single technical ID for all the FM calls that belongs to two different queues.

 See the next post how each queue FM calls are assigned to separated LUWs
