Overview of Formulas

Formulas allow you to create and store a set of objects and operators specific to a Loyalty Program. You can calculate values based on input from third parties and then take the resulting value into account within a promotion. Similarly to other objects, formulas are available for use in other promotions.

For example, a formula can calculate the average amount spent by a member in a specified period. Then the criteria can check whether the formula is greater than a predetermined dollar amount and have an action to reward a member a percentage of the formula value.

Formulas have the following characteristics:

• Associated with one Loyalty Program. A formula can be available for use by a promotion only if it is associated with the same Loyalty Program as that promotion.
• Comprised of a series of operators and objects. A formula contains logical mathematical operators, numbers, and objects representing defined attributes and numeric values. It can be defined only using attributes of type number or integer.
• Validated. The formula must be a valid mathematical formula. If the formula does not adhere to mathematical rules, then it is invalid and cannot be used.
• Used in promotions criteria and actions. Once validated, a formula is available for use in promotion criteria and actions. When used in promotion criteria and actions, the object is the formula and the attributes are a list of user-defined formulas.
