Deletion of Maintenance Task Lists 

Use

You can archive and delete maintenance task lists.

Prerequisite

You can only delete a maintenance task list(group counter) when the task list group is no longer being used in another object such as a maintenance order or a maintenance plan item. As soon as a task list group is in use, the system will not allow you to delete the group counters in it.

Features

You can delete a group counter at two levels or alternatively, set it with a deletion flag:

The system then sets a deletion flag that you can no longer undo. The group counter is logically deleted and will no longer be displayed at the maintenance task list level.

The group counter is only physically deleted by the archiving program. This program deletes all group counters with deletion flags from the database.

the system sets a deletion flag that you can undo if necessary. The system displays the group counter in the header overview.

As soon the group counter has been marked with a deletion flag, you can no longer assign it to other objects such as a maintenance order, single cycle plan or maintenance plan item.

You can physically delete maintenance task lists with the archiving program by selecting all task lists that have been marked with a deletion flag.
