I know that there are four types of RFC but my question is that how do you check whether it is an Synchronous or Asynchronous RFC?
Kindly share your valuable views here, thanks in advance.
Synchronous RFC waits for acknowledgement from the remote function module but Async RFC will not wait for acknowledgement. So pragmatically we will use 'WAIT UNTIL FLAG' statement in Asynchronous RFC to stop the rest processing unless & until the result returned back to the main program from remote function module.
