Understanding Invoice Signatures

When a legal document number is attached to an invoice, the system generates a signature. The signature is created using the formatted legal document number as element 4.1.4.1 of SAF-T PT. Once a signature is generated it will be saved in the database with a direct link to the document to which it refers. For each signature the system saves the version in the database of the private key used to generate the signature. No unsigned invoices are allowed in the system. You are not allowed to assign a new signature to an existing document.

To verify information for unsigned invoices, access the Work with Unsigned Invoices program by typing P743012 in the Fast Path.
