If you want to create and maintain authorizations in the R/3 System, you should create and activate two types of authorization components.
You maintain authorizations by choosing Tools
You maintain authorization profiles by choosing Tools
The R/3 System includes predefined authorizations and profiles. These can often be given to your users without modification, which greatly reduces the effort required to maintain authorizations and profiles.
You can also decide how to organize maintaining user master records and authorizations. You can have a single superuser conduct all user and authorization maintenance, or divide maintenance among decentralized administrators.
