In the detailed view of an asset in the history tab you should be able to see what the inventory exception was. At the moment you are unable to run a exceptions report once the inventory is closed but if the history tab was actually useful (gave specific information and not general) then you can find out what the exception was over the years.
Currently the Asset History displays 'An asset inventory occurred' but does not display detail. Asset displays the exception code from the last inventory conducted in Asset detail.
Would be helpful to add the Exception code to History detail:
O Asset found with no changes
C Asset found with no changes
N Asset not found
I New asset
