You can use RFC Trace to monitor the remote calls that your application or the R/3 System makes, and the instances on which they are executed. The RFC Trace generates a trace file of logged trace records that you can display and analyze further.

While the RFC Trace is switched on, the system records all Remote Function Calls made by a particular user or group of users.

The trace recording tells you:

• Which function modules have been called "remotely" from the program that you analyzed.
• Whether the RFC was successfully executed.
• The total runtime required for the remote call.
• Whether the RFC communication was as a RFC client or an RFC server.
• The instance on which the remote call was executed.
• The technical parameters of the remote instance.
• The number of bytes sent and received in the Remote Function Call
