® Execute with variantThe system displays a list that shows exactly where each functional location is used.

If you do not mark the field Status check, the system displays usages regardless of whether or not the technical object has a deletion flag.
If you do mark the field Status check, the system checks whether the technical object has a deletion flag. The existing usages are only displayed if it does.
