Hi,
When one system calls an FM in another system, a tRFC(transactional RFC) is used. This tRFC inturn calls a FM that passes the idocs to the target system.
tRFCs enable asynchronous communication, and hence they use the concept of queues.
qRFC acts as an intermediated layer between the tRFC and the application.
The tRFC call, enters the queue(qRFC), and the processes in the queue are executed in first in first out order.

Smitha.
