When an invoice is NOT part of a closed week, you simply need to void the invoice, make any needed changes to the order, then re-create the invoice. The invoice is part of a closed week if the invoice has a posting number assigned to it. If you are unsure if your invoice has a posting number, refer to the article How To: Check if an Invoice has a posting number. Please note: After voiding the original invoice, a new invoice and invoice number will be generated and the original invoice number will be lost.
