qRFC with Outbound Queue & Inbound Queue between two different SAP systems - One LUW per Queue Call

After calling the RFCs under a queue, the next commit work statement closes the current LUW and opens a new one. Here we have the report.. Execute it.

Step2. Here we have the report output.

 Step3. Source System: Tx- SMQR( Out Bound Scheduler). Select both the queues and double click on it.

Step4. Source System: Double click on the queue name.

Step5. Source System: So here we have two LUWs for two Queues. Process the queues.

Step6. Target System: Tx- SMQS( Inbound Scheduler). The snap shot of comparison of the TIDs.
