To Cancel and Reissue project invoices without a credit memo: (Portugal OfcioCiculado 2510/2026)

Hi, Can anyone help with this concern that we have. Thanks in advance.

Portugal invoices are created in oracle Projects and then transferred to receivables using standard billing process.

The Portugal Authority issued a circular recently - Ofcio-Ciculado 2510/2026- stating that if an issued invoice contains only a formal or minor error (like incorrect NIF, customer address or customer ID etc ), which does not affect the tax amount or VAT, then we should not create a credit memo for it to cancel the invoice. Instead we must cancel the invoice and issue a corrected invoice- that is, no credit invoice to be issued.
