When a user logs onto SAP multiple times a selection screen pops up.
If the user wants to continue with the multiple logon the following message is part of the option:
"If you continue with this logon without ending any existing logons to system, this will be logged in the system. SAP reserves the right to view this information."
If you have users who are logging in with other users login and need to view where this information is stored, check the table 'USR41_MLD' via transaction code 'SE16'.
The field 'Counter' tells you how many times the user have done a multiple logon.
