If you attempt to credit and rebill an invoice that was originally generated when there was no invoice bill code group assigned to the debtor’s invoice details, you will be to create a credit note and a rebill invoice as per usual via the Credit/Rebill process, irrespective of whether an invoice bill code group has been assigned to the debtor’s invoice details since the original invoice was created. That is because the Credit/Rebill process always uses the invoice details that were applicable at the time when the original invoice was created to determine how to group invoice items onto invoices.
