A quantity by unit against which you can define freight rates.
		You can choose from the units defined in Common. Many freight
		rates are based on distance and weight. Additional quantities/units enable you
		to define rates that are based on other units, such as volume, or define rates
		that are based on combinations of distance, weight, and other units.
Example 1
 Freight rate by additional
		  quantity/unit:
 Additional Rate Quantity: 1 pallet, Distance: 1000 km
Amount byDistance:
		  10
Example 2
Freight rates by combinations of units by
		  distance/zone:
 Weight: 10 kg
Additional Rate Quantity: 1 m³
Break Type: Minimum
| Distance: | 0 | 100 | 500 | 
| Amount byDistance | 10 | 15 | 20 | 
| Amount byWeight | 5 | 5 | 10 | 
| Amount byAdditional Rate Unit | 5 | 5 | 7 | 
 
In this example, freight rates are based on distance by
		  weight and volume. Shipment SH0001, from Amsterdam to Rotterdam, includes the
		  following details: Distance: 70 km, Weight: 50 kg, Volume: 7 m³
The freight costs for shipment SH0001 are:
 10 * 70 (distance) + 5 * 50 (weight) + 5 * 7 (volume) = 985
