# Stock Lot Unit Module

The `stock_lot_unit` module allows to define a unit and quantity on stock lot.

Lots with unit have the following properties:

> - no shipment may contain a summed quantity for a lot greater than the quantity of the lot.

> - no move related to a lot with a unit may concern a quantity greater than the quantity of the lot.

The Lot Unit field is added to the product. This defines the unit to set on new lot.
