parameter

Parameters dictate the characteristics of the formula such as the percentage of sodium, the pH level, the boiling point, the cost, the drying time, and the SPF level. The parameters of a formula are derived from the parameters of the items. Parameter values change when the item values change. The four types of parameters are: rollup (values pulled up and possibly scaled from the formula’s items), cost (values derived from production costs), informational (not rolled up nor scaled but can be used in calculations), and equation total (values calculated from values of other parameters).
