The table TaxVATNumTable is the table to add a record so that when creating a customer the VAT number can be selected.

This table is imprecise as the customer's document number can be a NIF, a NIE or a passport, we believe it is necessary that this table can identify what type of document it is, as later, when creating the invoices to send them to the SII, it may be that the customer's identity document is a passport, and the SII is prepared to receive the passport key, but it cannot identify what type of document this identification number belongs to, as it always creates it as a NIF.

It must be taken into account that the purpose of this request is to be able to send the invoices to the SII correctly, it is necessary to take into account the configuration of the additional fields for sending invoices with passport to the SII.
