How can I identify who an SAP login belongs to?
For example, login: C50521, and I am looking for name, surname, of C50521
Please, provide transaction if exists.
Go to SU01 and enter SAP login there. On the first tab you should see First and Last names, if they are maintained and if they are real. And of course if you possess proper authorizations.
UPDATE: If one have no access to SU01, SU10 (Mass editing of users) can be the option too.
