Show Correct PO Vendor in PO Analysis for Annually Duplicated POs

Right now, we store multiple years worth of PO data in our Ensite database (the one used for Purchase Order Analysis, NOT Purchase Order History). When we look up a PO that was duplicated in a previous year (such as a MMDDXX style PO# from the ASB), the PO Vendor shown in Purchase Order Analysis is just whichever Vendor was FIRST used. You have to look at the PO in Purchase Order History to see which Vendor the PO really went against. It seems like if PO Vendor info was copied over into the Ensite database (PurchaseOrderJournalDetail) it would prevent this from being an issue year over year.
