The Delete function lets you delete planning records that have already been posted.
If you choose Delete in activity type planning, plan records are deleted from the database only if no dependent data records exist. For example, you cannot delete an activity type on a cost center if activity input has already been posted to the cost center using this activity type. The R/3 System informs you if dependent records exist.
Note that the system only deletes the planning records when they are posted from the database.
