I understand dates and amounts need to be locked after a VAT return has been created, but it would be very useful to be able to add a comment line, so that if an invoice has to be cancelled and re-input to correct an error an explanation can be placed on the original entry to aid the audit trail
This would be very useful. working in retail we often have to amend an invoice with address or machine information and i do find it very frustrating that i can not amend the invoice details or add a note with the update information.
