Leveraging Eligibility Criteria to Dynamically Apply Calculation Rules

Another tool to consider when creating your calculation groups and rules is Eligibility Criteria. Eligibility criteria allow you to define rules that determine the conditions under which a calculation rule is applied or not.

For example, if you need to calculate demand for one or more of your rates, you might create separate calculation rules to calculate demand based on interval values of different units of measure (kWh vs kVarh for instance). You could create rules for each and include them in a single "Calculate Demand" calculation group, but assign eligibility criteria to each such that they are only executed when processing for the specified unit of measure.

See Eligibility Criteria in About Calculation Rules for more information about eligibility criteria and how they can be used with calculation rules. In addition, refer to The Big Picture of Rate Component Eligibility Rules in the Rates chapter for additional background on eligibility criteria.
