Define default product UoM at product category level.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Lets you set a default unit of measure on a product category and automatically apply it to products in that category.
This module adds a "Default Unit of Measure" field to product categories. When you open a product category form, you can pick a unit of measure (for example Units, kg, litres) that should be used by default for products belonging to that category.
- On the category form there is a button "-> Apply to Products" that updates the unit of measure of all existing products in that category. A confirmation message warns that this will apply to all products in the category.
- When you create a new product and choose a category that has a default unit of measure, the product automatically gets that unit of measure, unless you have already set one yourself.
- When you change the category of an existing product on the product form, the unit of measure is automatically updated to the category's default unit of measure, if the category has one.
The module works on product categories (product.category) and product templates (product.template). It does not change sales, purchases or stock documents; it only affects the default unit of measure stored on products.
