Diagnosis
Selecting 'RFC, Update' can lead to system performance problems.

System Response
If the checkbox 'RFC/Update' is selected, potentially an ABAP runtimemeasurement will be started on the target server for each RFC or updatecall (sequential, synchronous RFC calls to the same destination do notresult in another ABAP runtime measurement starting).
So this is how multiple runtime measurements can be started within ashort space of time, which can result in a heavy system workload. Thisis particularly the case with asynchronous RFC calls.

Procedure
A warning is issued.

Procedure for System Administration
Make sure that you really do need a detailed ABAP runtime measurement ofthe ABAP source code that is executed on the RFC server or in the updatetask. To determine the runtime of an RFC call or of a synchronousupdate, no special measurement is required on the server side.
