Relation between order position and campaign?

Hello!

I'm trying to build a solution to provide the possability to show orders (and/or order positions) connected to campaigns but can't find the tables providing this link. I've found CGPL_PROCJECT as the table for campaigns, but where is the relation between CRMD_ORDERADM_I and CGPL_PROJECT?

Thanks!
