auto_awesome What this module does
AI-generated from the code · Odoo 12.0Prevents selling more than one unit of a serial-tracked product on a single sale order line. If a product is managed by serial number, the quantity on the line must be exactly 1.
This module adds a validation rule to sale order lines. When a product is tracked by serial number, the quantity on the line cannot be different from 1. If a user tries to set a quantity other than 1, Odoo shows an error message and blocks the change.
The rule is applied automatically whenever the quantity or the product's tracking setting changes. It uses the product's unit of measure rounding to compare the quantity, so it works correctly with different units of measure.
This affects the sale.order.line model, which is used in sales orders and quotations. The module also adds a stored related field product_tracking on the sale order line, which mirrors the tracking setting of the product. This field is used internally for the check and is not directly visible to users unless added to a view.
No new menus, buttons, or reports are added. The change is purely a validation constraint that ensures each sale order line for a serial-tracked product contains exactly one unit. This is useful when stock moves should be unique per sale order line and per serial number.
