Product - Domain on Purchase UoM
By default in Odoo, on the product.template and product.product form views, the list of the available Purchase UoM is not filtered. (uom_po_id field)
So the UI is proposing all the uoms, even those that are not consistent with the selected main UoM. (defined in the uom_id field.)
This module extends the functionallity of product module, adding a domain on this field.
auto_awesome What this module does
AI-generated from the code · Odoo 16.0When you set a product's purchase unit of measure, Odoo now only offers units that belong to the same unit-of-measure category as the product's main unit. This prevents picking an inconsistent purchase unit.
This module changes the product form so that the Purchase UoM field is filtered by the product's main unit of measure.
- On the product template form (the same screen where you set the main Unit of Measure), the Purchase UoM dropdown now only lists units from the same unit-of-measure category as the main unit. For example, if the main unit is a weight unit, only other weight units are proposed.
- A hidden helper field,
uom_category_id, is added to the form and is automatically taken from the main unit's category; it is not shown to users. - The rule is applied on
product.template, so it also affects the product variants derived from it. - No new menus, buttons, reports, emails or scheduled actions are added; the change is limited to the selection available in the Purchase UoM field.
This is useful when you buy a product in a different unit than you sell or store it, but you still want the purchase unit to be compatible with the main unit. It reduces data-entry mistakes without changing any existing records.
