How to extract all project parties via a report?

Summary

Looking for a way to extract all project parties information via an analytics or bi publisher report.

In the Project Financial Management web page, through the Financial Project Settings, I can see a Tab showing all involved parties with the project.

I am looking for a way to extract this information via a report, preferably through Analytics but BI Publisher may be the only solution here it seems.

I found how to get the Team Members and the Project Customers, via the Analytics "Projects - Cross Subject Area Analysis" subject area.

I also found dedicated subject areas for Partners or Suppliers, but I can't find the link between them and the projects.
