thanks for your quick answers.
The Table usr41 cannot help me. i checked the table and the result is really strange. I have a logged user named EIPADM. Using Tcode SM51 can i see this user, but it dosn't exist in table USR41 (see attached screenshot).
I need a FM if it's availabe. The FM "TH_REMOTE_USER_LIST" needs the name of application server. My report don't know the name of any application server. I just need some FM like transaction SM04 or AL08.
Thanks again.
