Thai Localization - Inter Company Tax

This module works behind the scenes for Thai companies that use several companies in the same Odoo database and exchange invoices between them.

When Odoo automatically creates the matching invoice in the other company from a customer invoice, the new invoice lines are checked. If the source document is a customer invoice (out_invoice), the module looks at the Thai tax invoice information attached to that source invoice and copies the tax invoice number and tax invoice date onto the lines of the automatically created invoice.

• The tax invoice number and tax invoice date are carried over automatically, so users do not have to retype them.
• This keeps the Thai tax document references consistent between the two companies involved in the transaction.
• It only applies to lines created on invoices that come from the inter-company automatic invoicing process; ordinary invoice lines are not changed.

It touches the invoice line model account.move.line and relies on the inter-company invoicing and Thai tax invoice features provided by the modules it depends on. No new menus, screens, reports or scheduled actions are added; the change is purely automatic at the moment invoice lines are created.
