Allows to calculate products weight from its components.
You can update the weight for one specific product at a time and choose which bom should be used to know the components. Or you can run the calculation for many products at one time, this way, the first bom found for the product will be used to know the components.
If products' weights are expressed in different Unit of Measures, have a look to product_weight_logistics_uom module.
auto_awesome What this module does
AI-generated from the code · Odoo 14.0Calculate a product's weight automatically from its bill of materials components. Run it for one product with a chosen BoM, or for many products at once using the first BoM found.
This module adds a way to fill in the weight of manufactured products based on the weights of their components, instead of typing it by hand.
On a product form, next to the Weight field, a small "update weights" link opens a window where you pick the bill of materials to use. The module then looks at every component in that BoM, multiplies each component's weight by the quantity needed, and writes the total into the product's weight.
You can also select several products or product templates in a list and use the "Calculate Product Weights" or "Calculate Template Weights" action. In that case the module uses the first bill of materials it finds for each product; for templates it skips those with more than one variant.
Quantities are converted between the units of measure used on the BoM and on the components, so the result is consistent. If a product has no active variant, an error message is shown. The module only reads and updates the weight field; it does not change stock, prices or other data.
