Field help (VOL) 

This is the total volume of the packages of the document. The volume is automatically calculated by the load preparation function, but it can be modified.

The volume unit is defined by the volume unit of the first packaging from the delivery lines. If other products in the delivery do not have the same volume unit, the volume of the packaging for these products is converted to the volume unit for the first packaging in the delivery note. The conversion between these units is applied as defined in the table Unit conversion. The volume unit does however remain modifiable.
