Assigning SAP Organizational Objects 
Use
So that you can define roles using organizational data, you must create and edit assignments between SAP organizational objects and Organizational Management organizational objects.

For example, you want to restrict the task of buying certain materials to certain individuals within a specific organizational unit. This is achieved by creating an assignment between a purchasing group (purchasing groups are SAP Organizational Objects) and an organizational unit.
You can create assignments between any object classified as an SAP Organizational Object, and the Organizational Management objects – organizational units, positions, jobs, and work centers. You apply a validity period to these assignments, so that changes in responsibility can be shown.
Procedure

Entries in these fields allow you to confine the objects you edit to:
Enter a superior organizational unit if you want to create a relationship between an SAP organizational object and a position. You will subsequently be able to navigate from the selected organizational unit to the object.
You confine your work to specific SAP Organizational Object Types. This reduces the number of steps you perform later, if creating assignments.
You can work with all types of SAP Organizational Objects. Select an object.
Assignments between SAP organizational objects and organizational objects from Organizational Management can also be created in
