Authorization Inheritance
You can assign authorizations directly to a user or the user inherits them from parent business objects. Authorizations that are directly assigned always override inherited authorizations. The following hierarchy is used to determine authorization inheritance:
Portfolio –> Bucket
Bucket –> Bucket
Bucket –> Item
Bucket –> Review
Bucket –> Collection
Item –> Decision Point
Bucket –> Initiative
Initiative –> Decision Point
Initiative –> Phase
Initiative –>Item of Initiative
