I doing some testing with different views, I have created a view for SAM application details. It appears that DPA has added its own view with the same name with DP Performance appended to it.
I can delete my created view fine, but when I try to delete the DB Perrormance view, I receive the message 'Cannot delete "[name of view] DB Performance" view; it is a system view.'
Has anyone else come across this?
Here is an article discussing this very thing. I'd advise caution making edits directly to the database as there may be unintended consequences.
If you don't want the DPA integration any longer, you can delete the integration from settings...
