Yup, you can see which Purchase Order a vendor ledger entry is matched to by viewing the Application Entries window. Just go to the Vendor Ledger Entries page, select the vendor ledger entry, and that's it: view the Purchase Order No. column to see the purchase order number that the vendor ledger entry is matched to.
If the vendor ledger entry is not matched to a purchase order, the Purchase Order No. column will be blank*
