Mexican Addendum For Invoices For Volkswagen

This module extends the Mexican electronic invoicing (CFDI) addenda feature for invoices issued to Volkswagen.

On a customer invoice (account.move), a new "Addenda Volkswagen" tab appears, but only when the invoice's customer is configured with the addendum named "Addenda Volkswagen". In that tab you can fill in the VW Division, the VW Applicant Name and the VW Applicant email. Whether the tab is shown is decided automatically by a stored computed flag based on the customer's addendum setting.

On each invoice line, an extra column "VW Product Reference" is available (shown only for Volkswagen invoices), so each product can carry the reference code Volkswagen expects.

The module also provides an addendum XML template named "Addenda Volkswagen" that builds the Volkswagen addendum structure from the invoice: division, currency and exchange rate, supplier code/name/contact email, applicant name and email, and one part per invoice line with position, material number, description, quantity, unit of measure, unit price, line amount and the purchase order reference taken from the invoice reference field.

It depends on the Mexican CFDI accounting module and only adds fields, a form view and the addendum template; it does not add menus or scheduled actions.
