Maintenance Authorization for Maintaining Dependencies
In Customizing for Variant Configuration, you can define new maintenance authorizations by choosing Define Maintenance Authorizations.
You can assign these authorizations to dependencies.In the user master record of the relevant users, you enter authorization object C_LOVC_DEP with the maintenance authorization value that you want the user to have.
Each user can only maintain dependencies whose maintenance authorization matches that in their user master record.
A dependency has maintenance authorization 100.
User A has the authorization to maintain dependencies with maintenance authorization 050–150.
User B has the authorization to maintain dependencies with maintenance authorization 200–300.
Only user A can maintain the dependency with maintenance authorization 100.
When you restrict a dependency to certain user groups, please note the following:
If you delete a local dependency, you delete the entire dependency, so the system checks your authorization to change or delete a dependency, as well as your authorization for the object, if you do this.
