In Italy, an issued invoice is considered valid if the electronic XML version is sent to the SDI and is either delivered or delivered and accepted. If an invoice is sent with errors in the XML file, such as a correct VAT number but an incorrect tax code, it is marked as rejected. A rejected invoice must be corrected and reissued with the same numbering; a credit note cannot be sent because it was not delivered and accepted. In these cases, Business Central must allow the invoice to be corrected without generating a credit note and must use the same numbering in the registration of the corrected invoice.

Thank you
