QML Report listing CAD Docs without a representation

This is a share post. I was looking for a report that would list any Latest Released CAD Docs that do not have  a WVS Representation linked to them. The report looks for null values for the Derived Image. We all rely upon PDF and STEP generated files from the WVS service. When they do not exist, users can question the system's accuracy. Since the WVS publishing services are not 100% reliable, make sense to monitor for completeness. I know you can use the WVS Scheduler to just publish any by Context that are missing a representation. I also have WVS actions on search results toolbar. This way you can control what you republish. From this report, you can export to excel and target a search query and be specific on what you send to the publisher. My only issue with the schedule tasks is that you have no idea how many will be generated. This report gives you a quick check.
