Naming Convention for SAP Authorizations 
Naming Convention for SAP Authorizations
The R/3 System is supplied with a set of predefined authorizations. You can display the predefined authorizations by using the user and authorization information system.
For predefined authorizations, you can also use the naming convention described in
Predefined Profiles: Naming Convention. 
In any case, SAP recommends that you do not create profiles and authorizations manually. Use the Profile Generator instead.
