Allow to change the product UoM if the new UoM is in the same category and has the same factor.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Allows changing a product's unit of measure after it has been used in stock operations, but only to another unit in the same category with the same conversion factor.
This module relaxes the standard restriction that prevents changing a product's unit of measure once it has been used in a stock picking. With it installed, you can still update the unit of measure of a product, but only when the new unit belongs to the same unit-of-measure category and has exactly the same conversion factor as the current one.
- The change is applied on the product template (
product.template), so it affects the product itself and its variants. - If the new unit does not share the same category and factor, Odoo blocks the change and shows an error message explaining that the unit cannot be changed.
- The update is performed directly on the product records, so it works even for products already used in stock moves.
This module does not add menus, buttons, reports, or scheduled actions. It only changes the behaviour of saving a product when the unit of measure field is modified. It depends on the Inventory (stock) app.
