there is a short dump in ECC
it called an RFC custom function module in SRM
"connection closed (no data)"
there is no short dump in SRM
there is entry in SM21 in SRM
Q02 Stop Workp. 11, PID 10223842
it could not be time limit rdisp/max_wprun_time exceed because there are many other rfc calls in the same program that are much bigger than this one.
i tried to simulate a no-data scenario by debugging and making the rfc function module not return any data. but it was ok, its very simple function module with only one select query.
the same code is running correctly in other ECC systems pointing to the same SRM. (we switch them).
