Diagnosis
You want to delete one or more scheduling entries which are currentlyrunning.

System Response
The entries cannot be immediately deleted because background jobs stillhave to undo the scheduled actions (site deactivation and/orsubscription reroutings to target sites).
Instead of deleting the entry, the deletion process will set thescheduling end date to a past date (ie. to the date of yesterday) sothat the next background job running will undo all scheduled actions. Inaddition the entries will be marked for deletion on saving (status'Deleted').
Not yet running scheduling entries (status 'Scheduled') can be deletedat any time. Scheduling entries which have been ended successfully(status 'Done') will be automatically reorganized after a given time.
