Sorry,
I hit the 'enter' key before I was done. Let me have a 'do over':
CaseyC,
What you are running into here is a limit of Report Writer and why you see such things as 'field 1' & 'field 2' as the field names. Report Writer will not let you add more than one 1-many relationship in a single branch. You are trying to join PM10300 to PM10201 AND PM10300 to PM10100. That's two 1 to many relationships. You can join PM10201 and PM20000 without a problem to get the pordnmbr field you need, but you would also get a complete set of distributions for each record in the PM10201 table that matched the PM10300 document.
What you need is a couple of sub-reports, which is what has happened behind the scenes - sort of. This is what you are trying to do, generally, that Report Writer does not support:
PM10300 (PM Pmt WORK - the checks)
PM10201 (PM Apply to WORK - the vouchers being paid) (1 to many with PM10300)
PM20000 (PM Trx Open - where the PO number lives) (1 to 1 with PM10201)
PM10100 (GL distributions) (1 to many with PM10300)
If you are willing to give up the information on the distributions, you can get your PO Number.
You would probably be better served to create a SQL view and then build a report using a different tool to give you the information you need.
Kind regards,
Leslie
