You use qRFC with inbound queue if the application itself determines when it processes the inbound qRFC LUWs in the target system. You also use qRFC if you want to remove the connection between the transfer of LUWs and their execution.
As mentioned in previous sections, qRFC with inbound queue always means that an outbound queue also exists in the client system.
Using an inbound queue separates the transfer of qRFC LUWs from their processing. The outbound queue is used to write the qRFC LUWs to the inbound queue of the target system. This reduces the processing workload in the sending system to the transfer of LUWs to the target system.
LUWs arriving in the inbound queue are read and processed from the queue either by the QIN Scheduler, or by program calls from an application program.
