Field help (NETWEI) 

Net weight of the delivery. This is the sum of the unit weights of the products (of the sales unit) multiplied by the quantities in SAL of the various lines constituting the delivery. This weight is automatically calculated but it can be modified.

The weight unit is defined by the weight unit of the first product in the delivery. If other products in the delivery do not have the same weight unit, the weight of these products will then be converted to the weight unit from the first line in the delivery note. The conversion between these units is applied as defined in the table Unit conversion. The weight unit does however remain modifiable.
