Q: A voucher was rejected and notes were entered that it should be paid on another purchase order (PO). Why is the invoice still unpaid and does not appear on the other PO?

A: Vouchers should not be rejected to be paid on another PO. It is best practice to approve the voucher for payment and work with the supplier to reference the new PO for future invoices. Rejected invoices are not paid and entering notes on the voucher does not automatically trigger an invoice to be applied to a new PO.
