Why would I need to remove duty roles from a role hierarchy?
If your custom duty roles enable actions and user interface features that your enterprise doesn't want users to perform in your application.
Note:
Don't remove duty roles from predefined job or abstract
roles in the reference implementation. In the Security Console, you
can identify predefined application roles by the ORA_
prefix in the Role Code field. You must copy any role that doesn't match your needs, and
then edit the copy.
