AI-generated from the code · Odoo 19.0

Lets you record and see stock quantities in a second unit of measure (for example, buy in boxes but track in units) on products, transfers and delivery slips.

This module adds a second unit of measure to stock operations, so you can work with a unit that differs from the main one used for inventory.

  • On a product (both product.template and product.product) you can set a "Second unit for inventory" in the Inventory tab, and the product form and product lists show a "Secondary Unit" button and column with the quantity on hand expressed in that second unit.
  • On transfers (stock.picking), detailed operations and move lines, you can enter a quantity in the secondary unit; Odoo automatically converts it into the main unit quantity (product_uom_qty on stock.move and quantity on stock.move.line). Changing the main unit recalculates the secondary quantity.
  • When a move line is created, the secondary unit of the related move is copied onto it automatically.
  • Moves with different secondary units are not merged together.
  • The delivery slip report shows an extra "Secondary Qty" column for both detailed and aggregated lines.

Fields and screens are visible to stock users, and the unit fields to users allowed to manage units of measure.
