Oracle Projects uses organization hierarchies to control project ownership, resources, and burden schedules. You control which organizations in an operating unit can own projects and tasks by associating the operating unit with a Project/Task Owning Organization Hierarchy. You define which organizations can charge expenditures to projects in an operating unit by associating the operating unit with an Expenditure Organization Hierarchy. A project can use different burden schedules for any organization belonging to the Project Burdening Hierarchy.

Global organization hierarchies are hierarchies that contain organizations from multiple business groups. By using global hierarchies, operating units can broaden their project resources beyond their own business group, using resources from other business groups to own or perform project tasks.
