Checks (CS-AG/PM-PRM-TL)

Use

If you change maintenance task lists (PM task lists) or task list objects using 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.

You can delete your data in the following ways:

Over the entire time period

On the key date

Deleting Over the Entire Period

If you delete over the entire period of time, all task lists which meet your selection criteria are deleted (for example, for equipment and status).

You can also enter existing deletion flags as a selection criterion. If you do not enter deletion flags explicitly as a criterion, task lists are deleted regardless of whether or not they have a deletion flag.

Deleting on the Key Date

Deleting on the key date is advisable above all if you have accumulated historical data statuses which you no longer need.

The subsequent checks only concern maintenance task lists which you have created with a change number.

If you delete on a key date, all change statuses ending before this key date are deleted. For the periods before the key date, it is not important whether inspection plans or inspection plan objects have deletion flags or if you have previously deleted them online.

In addition, the system checks change statuses that lie on or after the key date. In this case, the deciding factor is whether you have already deleted these change statuses online. The system deletes these change statuses from the database even though they lie on or after the key date. For this, there are no time gaps. This means that if a change status does not have an online deletion indicator, the following change statuses are not deleted from the database, even if you already have an online indicator.
