SQL & PL/SQL

Hi guys, I'm trying to help out some folks in AP with an easier access to view Open Interface rejects. I already knew the relation between AP_INVOICES_INTERFACE and AP_INTERFACE_REJECTIONS was INVOICE_ID AND PARENT_ID (respectively). Now I've seen that some invoices also have a relation between AP_INVOICE_LINES_INTERFACE and AP_INTERFACE_REJECTIONS, same columns related (INVOICE_ID AND PARENT_ID respectively).

What I'm having a problem with, maybe I've just been sitting here too long, but I cannot get it all into one report.

I tried this, but it's giving me way more records than it should:

SELECT AIR.CREATION_DATE
, AIR.REJECT_LOOKUP_CODE
, AII.PO_NUMBER
, AII.GROUP_ID
, AII.VENDOR_NUM
, AII.INVOICE_NUM
, AII.INVOICE_DATE
, AII.INVOICE_AMOUNT
, AII.SOURCE
FROM AP.AP_INTERFACE_REJECTIONS AIR
, AP.AP_INVOICES_INTERFACE AII
, AP.AP_INVOICE_LINES_INTERFACE AILI
WHERE (AII.INVOICE_ID = AIR.PARENT_ID AND AII.ORG_ID = 162)
OR (AILI.INVOICE_ID = AIR.PARENT_ID AND AILI.ORG_ID = 162)

Any thoughts on where I mucked it up or how I could actually go about this? What shows in the actual Open Interface app is a good start, it's just missing some fields like vendor name and reject lookup code.

Thanks for any help!
