Which tables and fields show the relationship between payments holder and Projects

SOLVED

Hello everyone,

I'm going to create a report using Crystal report that shows payment info for each purchase invoice including cheque#, payment date, invoice#, Project name I know that Payment info stored in tPmtHdr and was able to almost create the report, but the only thing I couldn't figure it out is how to include project name in the report :( 

Does anybody know how to create relationship between  tPmtHdr  and tProject?

Thank you in advance.
