Delete PI AF objects

You delete database objects (elements, event frames, and templates) from the PI System Explorer browser. If the object references other objects, you can also select to delete the references, such as references between elements, event frames or event frames and elements. For more information on references, see Element references.

1. To delete a PI AF database object, click the Element, Event Frame or Library button in the navigator.

2. In the browser, navigate to the object you want to delete.

3. Right-click the object, then click Delete.

4. In the Delete window, you can delete objects that have references to other objects, as well as those that do not.

   1. If the object has references to other objects...

   To...	Do this...
   Delete an object and all the references pointing to it without immediately checking in the changes.	Click Delete this object and all references to it. Check in is required to complete this action.
   Delete the currently selected reference only without immediately checking in the changes.	Click Only delete this reference to the object. Check in is required to complete this action.
   Delete the object permanently from your PI asset model.	Click Permanently delete; this action is irreversible. Caution: This option results in the immediate deletion of the object and its references from the database.

   Caution: If the object is an event frame, selecting any of the options in the Delete window results in the immediate deletion of the event frame.

5. If the object does not have references to other objects...

Tip: By default, PI AF automatically deletes analyses and notifications that reference a deleted element. You can change this behavior by disabling the /EnablePropogationOfTargetDeletion parameter in the PI AF Diagnostics utility. For more information, see Deletion of elements, notifications, and analyses.

6. Click OK.

   Note: If you did not permanently delete the object, remember to click the Check In button to apply and save your changes to the database.
