Делить можно только по количеству? Возможно ли по весу?

b) Packed quantities in transportation chains:
If a delivery is in various shipments and if an item quantity is packed in these shipments, the split separately reassigns the packing quantities of the individual shipments during the distribution of packing quantities. In other words, the split supports multiple packing in transportation chains. As the split quantity entry, you may use only highest-level shipping units from the same shipment. If an item weighs 30 tons and if you can fit a maximum of 25 tons in a truck and a maximum of 27 tons on a ship (the truck plus 2 tons), you may only enter a maximum of 3 tons (smallest quantity of all the shipments that was not packed) without entering shipping units (as quantity not packed). You can deactivate the checks and calculations of this special function in Customizing.
