A Rate Component with a Time Span Comparison

A rate component that is only eligible for senior citizens has the following eligibility rule:

Birth date equates to that of a senior citizen
This rule requires only one eligibility group on the rate component. It would look as follows:


Group No.	Group Description	If Group is TRUE	If Group is FALSE
1	Customer Is A Senior Citizen	Apply rate component	Skip rate component

The following criterion is required for this group:


Group 1: Residential, Calif, Senior
Seq	Field to Compare	Comparison Method	If TRUE	If FALSE	If Insufficient Data
10	Main person characteristic: Date of Birth	Algorithm: True if senior	Group is true	Group is false	Group is false

The criterion contains a time span comparison. Time span comparisons are used to compare a date to something. In our example, we have to determine the age of the customer based on their birth date. If the resultant age is > 65, they are considered to be a senior citizen. To pull this off, you can take advantage of a comparison algorithm supplied with the base rate component as described below.

Field to Compare. The person characteristic in which the customer's birth date is held is selected.
Comparison Method. We chose a comparison algorithm that returns a value of TRUE if the related field value (the customer's date of birth) is greater than 65 years (refer to the RECC-TIMESPN algorithm for an example of this type of algorithm).

You'll notice that if a value of TRUE is returned by the True if senior algorithm, the group is true (and we've setup the group to indicate a true group means the rate component is eligible).

Note:

The time span algorithm can be used to compare days, weeks, months, etc. Refer to the RECC-TIMESPN algorithm type for more information about this algorithm.
