Problem

Recently a user noticed that an Asset prioritisation analysis no longer exists in the production environment. The analysis was applied to assets. The applied consequence priorities still exist. Normally, as far as I know, an analysis can't be deleted if it was applied to assets.

Further analysis found that the AP analysis still exists in the TEST environment that is a copy of a few months ago. How can it be that a prioritization analysis is 'deleted' although it was applied to assets?

Solution

Asset Prioritization Analyses that have been completed and applied to assets should not be able to be deleted without special care. To my knowledge there is only one case where this behaviour can be overridden and that is when an Analysis has had it's scores cleared. There is a method in the tools menu of the Asset Prioritixation Analysis called "Clear Results" that is only available once an Analysis has been applied. If "Clear Results" is invoked then the Asset Prioritization Analysis can be deleted.

Clear results is the method that we created to allow for some flexibility in deleting analyses that have been applied in error or are totally obsolete and a potential source of confusion. So if Clear Results was invoked then it is likely that the person deleted the analysis intentionally.

Unfortunately, there is no way to tell after the fact if "Clear Results" was done, or not, and by whom because our deletions are hard deletions. However, since the object wasn't deleted in Test you can probably see if "Clear Results" was invoked in Test by checking on the Asset prioritization's History view, see screenshot.
