Freight cost calculation based on quantity

Hi!

I was trying to find a solution for the following requirement myself with no success. Maybe someone had something similar and can advise on how to fulfill it.

Requirement:

Shipment cost calculation on delivery level based on pallet quantity.

Example.

Shipment document 1000001 contains 2 deliveries which will go to different customers.

Delivery1 - 8 pallets. Transportation zone destination ZZ01.

Delivery2 - 3 pallets. Transportation zone destination ZZ02.

Tariff depends on transportation zone and quantity of pallets. Means we need pallets quantity as a scale base.

Calculated cost for Delivery1 is 8*10 EUR = 80 EUR

Calculated cost for Delivery2 is 3*12 EUR = 24 EUR

Total freight cost for the document is 104 EUR.

I created a condition type with Scale base - quantity

Calc. Base - Delivery

Calculation Type quantity.

When creating shipment cost document, quantity on delivery level is not populated. Also there is an error message related to quantity conversion.
