Delete No-Add Report

Del No Add means that you have a delete record for a Make, Model, Year, Engine (if any), LineCode, MPCC and don’t have a corresponding add for the same.

So, it could indicate dropping of coverage. It might also occur if you fix an overlap, deleting one of the overlapping applications and not changing the other. It can also happen if you do not run AutoMap on Map Applications after importing a new vehicle table or source applications, or changing a helper map.

To check, go to Map Applications and do View > Show Unmapped. Compare against the applications in Del No Add. You can also export a complete file and look for matching applications. After checking a few you may notice a pattern that will tell you what happened.
