This version of the CalculationScaleLookup
command is intended for calculation scales that are based on quantity. It returns:
|base monetary value
||sum of net prices
||sum of actual quantities
|weight of each item
||net price of each item
Appropriate for discount and shipping scales. (The discount/charge is determined from the quantity, and spread back to the OrderItems in proportion to their "net prices".)
If the quantityUnit attribute of the CalculationScale is not empty, the "lookup number" is the sum of followings.
- The "actual quantities" of the OrderItems, converted to the QuantityUnit specified by the quantityUnit attribute of the CalculationScale.
- The mathematical weights are the "net prices" of the OrderItems.
But if the quantityUnit attribute of the CalculationScale is empty, the "lookup number" is the sum of the quantities of the OrderItems. The "base monetary value" is the sum of the "net prices" of the OrderItems. The "result multiplier" is one.
