Synchronous COMMUNICATION is implemented when there is a need for IMMEDIATE return of data (response) from the receiving system to the sender system. The receiving system should be active at the time this communication is made so that it can process the function call at that very time. This communication is very helpful when real time response is required or when results are required immediately from the destination system.

Synchronous RFC is based on synchronous communication which means both the source system and destination system (Client & Server) involved must be available at the time function call is made.

sRFC is a means of communication between systems where acknowledgements are required. The resources of the Source System wait at the target system and ensure that they deliver the message/data with ACKD. The Data is CONSISTENT and reliable for communication.

The only ISSUE is if the target system is not available, the source system resources wait until target system is available which may lead to the Processes of source system to go into Sleep/RFC/CPIC Mode at target systems and hence blocks these resources.

Synchronous RFC can be used for

• For communication between systems.
• For communication between SAP Web Application Server to SAP GUI.
