This version of the
command is intended for calculation scales that are based on unit shipping
charge. It returns:
|base monetary value ||sum of shipping charges divided by sum of actual quantities|
|lookup number ||sum of shipping charges divided by sum of actual quantities|
|result multiplier ||1|
|weight of each |
|shipping charge divided by actual quantity of each item|
Appropriate for "per item" "shipping" tax scales, especially where a maximum
tax per item may be specified.
Both the "lookup number" and the "base monetary value" are the sum of the
shipping charges for the OrderItems, divided by the "result multiplier". The
"lookup number" is converted to the currency specified by the currStr
attribute of the CalculationScale. The "result multiplier" is the sum of the
OrderItem quantities. The mathematical weights are the shipping charges, each
divided by the OrderItem quantity.
