#9434 [Main]-"Factura Duplicada" error message appears under SII History if you use the same Vendor Invoice No. for the same Vendor (VAT Registration No.) in different documents in the Spanish version.
In the Spanish version with SII enabled, users now get a non-blocking warning when a purchase document's Vendor Invoice No. or Vendor Cr. Memo No. matches a posted entry of the opposite document type for the same vendor and date. SII would later reject such a document as 'Factura Duplicada'.
