Report all shared objects

Hi,

we have ProjectLink on Windchill 9.1 but I think it will be the same in Windchill 10.

How can one get a list of all objects that where shared to a project context?

I have tried to write a report in Query Builder. I have a project class, an EPM Doc class (we don't use Parts) bud I don´t know how to connect them togather.

Depends on Joins, report returns all EPM Docs (from all contexts) or nothing.

Can you help me find the right join, please?
