I have found that Query Builder works with interface classes, not just modeled classes. So, I have a report like the one you want that uses an interface that PRs, ECRs, ECNs, and ECTs all implement that allow the same report to show results for any of them. And by using outer joins, you can see which workitem from which workflow has which primary business object for each of them. You cannot get type-specific attributes (since those are not defined on the common interface class), but if you are happy with the basic info and/or a link to the primary business objects, then this approach is great. I am at the PTC Conference, but if you want a how-to on this, then let me know so I can send it next week when I get back from Las Vegas. Al Anderson
