Query Builder Report: getting the related Promotion Requests of a Drawing

Hi,

I am searching for a Query Builder Report definition to get informations of Promotion Requests that have collected specific Drawings (EPMDocuments).

With other words: the search criteria should be the EPMDoc's Number and the result should be the Number (and some additional infos like Status) of every Promotion Request where this EPMDoc is a part of.

I found this report which I try to modify to add a connection to EPMDocuments but I don't know what tables and joins are necessary.

Can you help me?

Thanks!
