Dear Abdellatif ,
I want then to deactivate this trace, but I must first find out for which user it is activated.
Can someone tell me how to check which user has carried out the action?
you can activate the user trace by running Tx SM04 and activate trace , accordingly this action will be stored in the logs (SM21) , so you can filter all logs related to the Tx SM04 since the warning Message Appeared and check the following message "Trace activated for user X"
X is the required user
anyway
The user trace is stored in the trace files, dev_w* , so you can check the user also there .
Best Regards
