Hi Angelo,
I have found few problems with your implementation.
1.In your PFCG role why activity 01,02 is provided when it was only display '03' activity.so please remove activity 01 & 02(Create or Change or any other activity present like Delete etc).
2.I asked for ST01 trace and not SU53.So please switch on the trace before executing the steps and then switch off and attach the same screenshot for further analysis.
Hope this helps.
Regards
Pradeep
