How to confirm a voucher when the following error ‘This is the last voucher against PO’ occurs?

Cause: System shows ‘This is the last voucher against PO, Adjust all balance amount of advance in current voucher’ Quantity of GRN is the same as PO.The advance given was more than the full receipt amount, so the system was not able to adjust automatically.

Remedies: User can create a debit/credit note to adjust the excess advance or can reverse the balance advance then create the voucher again.
