Reversal of invoices
When an original invoice contains errors, such as unit cost mistakes, you can replace the original invoice by reversing it. The replacement for the original invoice contains the updated information. You can reverse an invoice without creating a return transaction.
The status of the invoice, the credit memo, or the debit memo that is being reversed must be Approved or Paid. When reversing an invoice, the user default insert site does not have to be the same site as the site specified on the original invoice. If the user default insert site is different from the original invoice site, then the reverse invoice uses the site specified on the original invoice. However, the user default insert site must belong to the same organization as the original invoice.
When you approve the reversal or the pending reversal of an invoice, any details that were part of the original invoice are reversed. All records that are related to the original invoice are updated with the new information, such as unit cost. Documents that were attached to the original invoice are added to the replacement invoice. The original invoice becomes a history record.
