projectUsersMM field
When I navigate to the Projects list, select "Projects I'm On", and edit that filter, I notice that there's a field called projectUsersMM that looks like this:
projectUsersMM:ID=$$User.ID
projectUsersMM:ID_Mod=in
This gives me the impression that there's a field (projectUsersMM) that tracks all users attached to a project. My question is, how do I access this field from my own report? I've tried a few report types (Project, Task, Hour, User...) but have not seen this field listed.
My overall goal is to build a report that lists all planned hours, by project, and filtered by Product Owner. I know I call pull in Product Owner in a Project report by utilizing collections (which I've done), but then I can't build a chart off of that field. I'm hoping that if I can access projectUsersMM, I'll be able to pull in just Product Owners and use it in a chart.
