How to trace RFC calls

Integration projects where we deal with different systems communicating between each other are pretty challenging.

Sometimes one cannot even be sure about single BAPI whether its call properly reached the system or not.

One of the ways how to simple check if RFC function residing in SAP (e.g. BAPI) was called can be achieved in TA ST05. Here it is possible to set so called RFC Trace. This is functionality which listens on calls from remote systems and tracks it down.

All what needs to be done to set this trace on, perform the remote call to SAP, deactivate the trace and analyze the trace results:
