Purchase Order Weight and Volume

This module adds physical measurements to purchasing. On each purchase order line, Odoo computes a Weight and a Volume by multiplying the product's own weight and volume by the ordered quantity. These two columns are available in the order lines list but hidden by default, so users can switch them on when needed.

On the order itself, the total weight and total volume are calculated automatically from all lines and shown with their units next to the order totals. Two checkboxes on the order let users decide whether the weight and the volume appear on the printed document.

In Settings, under Purchase, two new options let a company choose whether order weight and order volume are displayed on purchase orders at all. Both are enabled by default, and they apply to every order of that company.

The printed Quotation and Purchase Order reports gain extra columns for line weight and line volume, plus a small summary table showing Total Weight and Total Volume, each controlled by the checkboxes on the order.

The module extends purchase.order.line, purchase.order, res.company and res.config.settings. It relies on the weight and volume already recorded on products, so products without those values will show zero.
