Use
You should only delete assignments between Organizational Management objects and SAP Organizational Objects only if you want to erase all record of an assignment from the database.

Deletions should only be necessary if positions have been created incorrectly or by accident. If you want to indicate that responsibilities have changed, use the delimit feature instead.
Prerequisites
You are in the Assigning SAP Organizational Objects: Initial screen and have selected the organizational unit and SAP organizational object, which you want to edit. (See
Assigning SAP Organizational Objects)Procedure
Another screen appears, displaying the Organizational Management objects you selected.

The tree structure can display additional information, including existing assignments with SAP Organizational Objects, and other Organizational Management objects in the organizational plan. To adjust the data displayed so that it meets your requirements, choose View.
A message appears asking you to confirm that you want to delete.
The system deletes the assignment.
