There is a PM Report that shows % due, but it's of marginal use in my opinion. Better option...Do you have OneView Foundation licensed so you can use Watchlists? If so, I'd recommend you setup a Watchlist on top of the P12071 (PM Backlog) with focus on the %Due field. If you setup your Queries and Watchlist correctly, you can pretty easily get alerted to overdue PM's.
Another Option is the new UXOne Landing pages. I'm pretty sure they have built Overdue PM in to the Alerts on the UXOne page.
If you or your team aren't already part of the Quest JDE CAM Special Interest Group (SIG) I recommend you joining. We have a considerable amount of recorded monthly webex content that covers some of these concepts, and we have regularly scheduled monthly meetings and a full 14 session block at InFocus conference dedicated to JDE CAM and Maintenance Storeroom operations. You can find the Quest SIG's at
www.questdirect.org or feel free to message me and I'll put you in touch with the SIG President to get on the mailing list.
