If you change maintenance task lists or maintenance task list objects with a change number, the task list consists of several change statuses. If you never change with a change number, the task list and all its task list objects have only one change status.

If you delete a change status online in a maintenance task list with several change statuses, a change status for further processing will only be blocked for this one, together with all lower-level objects. You can still access any other change statuses.

If you set a deletion flag for a change status in a maintenance task list with several change statuses, the deletion flag is set simultaneously in the entire maintenance task list. If you enter deletion flags as a criterion for an archiving session, the entire task list with all the task list objects will be archived and deleted. Similarly, if you cancel a deletion flag, this always applies to the entire task list.

To delete a task list with several release statuses completely from the database, choose one of the following options:

• Set a deletion flag in the task list header. For the archiving session with the deletion program, choose Deletion flags as a selection criterion. For more information on setting a deletion flag in the task list, see PM - Maintenance Task Lists.

• Specify the task list completely in the selection criteria for the archiving session and delete Over the entire time period.
