auto_awesome What this module does
AI-generated from the code · Odoo 18.0Limits purchase order lines to a single VAT tax, preventing users from selecting more than one VAT tax on the same line.
This module adds a control on purchase order lines so that only one VAT tax can be chosen per line. It works together with the account_tax_one_vat module, which provides the shared rule, and applies it to the purchase side.
Where it appears: - On the Purchase Order form, in the order lines, when you edit the Taxes field of a line.
What it does: - When you change the taxes on a purchase order line, Odoo checks the selection and warns you if more than one VAT tax is selected. - The same rule is enforced when the line is saved, so an invalid combination cannot be stored.
Which areas it touches:
- It extends the purchase.order.line model, so it affects purchase orders and their lines.
- It relies on the shared logic from the account_tax_one_vat module.
No new menus, reports, or scheduled actions are added by this module. The behaviour is limited to the tax selection check on purchase order lines.
