System Statuses in Work Breakdown Structures 
The active system status determines which business transactions you can perform with work breakdown structures and WBS elements. System statuses are passed from the project definition to the WBS elements and from the WBS elements to the subordinate WBS elements. The system statuses Locked and Final billing are exceptions to this.
You can cancel certain statuses, for instance Technically completed, Closed and Deletion Flag. When you do so, the previous status is set. You cancel system statuses on by one, until you arrive at a status that cannot be canceled. You cannot cancel system statuses that are set automatically (in the background by the system), for example Partially released.
If you cancel the statuses Technically completed or Closed, the system automatically cancels this status in the superior WBS element. However, the system does not cancel the status in subordinate WBS elements.

The Deletion Flag status is not set automatically in superior WBS elements.
