Queued Remote Function Call (qRFC) 

 

Purpose

All types of applications are instructed to communicate with other applications. This communication may take place within an SAP system, with another SAP system, or with an application from a remote external system. An interface that can be used for dealing with this task is the Remote Function Call (RFC).  RFCs can be used to start applications in remote systems, and to execute particular functions.

 

Integration

In contrast the first version of RFC, synchronous RFC (sRFC), which required both participating systems to be active to form synchronous communication, subsequent generations of RFC now provide a considerably extended range of functions (for example, serialization, guarantee that processing occurs once, and the receiving system does not have to be available). These features were further enhanced through the queued RFC with inbound/outbound queue.
