In trying to reconcile PORNI for the end of the Jan-Mar quarter, we found that two items that were in QC on 3/31/10 do not show on PO-J-B for that date. Going back we found that those items don't show on PO-J-B for prior dates when they were in QC, going back to the beginning of December, at least.
 
The odd thing is, if I receive one of those items as of yesterday, buy it off today, then run PO-J-B for yesterday... the item is on the report! The only thing that has changed in the mean time is that I edited the Vendor (nothing changed, just tabbed through and saved), and there is a different PO number.
