Mexican invoices all contain a Mexican UUID Number which is an invoice number that is provided by the Mexican SAT authorities. It appears as a standard field on electronic documents and is 36 characters long and must be captured for government reporting purposes. You can activate the MexicanUUID field in the Settings > Invoice Processing > Capture Profiles > Field Settings.

Mexican invoices also have two types of withholding taxes. Activate these fields as required.

• Impuestos sobre la Renta can be extracted into the ISRRetention field.

• Retenciones de IVA can be extracted into the AmontWithholdingTax field.

For more information on these fields, see Withholding Tax Amount / ISR Retention (Mexico).

Amount cross validation ensures that both values are subtracted from the total, as expected.

When exporting the withholding tax to SAP or writing it to a CSV file, both values are summed up into a single value. When exporting to XML, a database, or an ERP connection, both values are exported individually.
