How to connect the nonconf table

I am trying to write a BAQ based around the RMA data and nonconf table as a client wants to show only those RMA that are pending or the trn typ is R, from what i can gather but i can’t connect them. I can connect the RAM dtl, head, rcpt and dis but its coming up with too many rows.
Can anyone suggest how to connect them as the lot num, rmanum or POnum isn’t working.

RmaDisp table has RMA# and NonConfID
