Mexico
Mexican invoices all contain a MexicanUUID number that is an invoice number that is provided by the Mexican SAT authorities. It is displayed 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 ISRRetention and AmountWithholdingTax.
Amount cross validation ensures that both values are subtracted from the total, as expected.
When exporting the withholding tax to SAP ECC 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.
