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.
| Group No. | Group Description | If Group is TRUE | If Group is FALSE |
|---|---|---|---|
| 1 | Customer Is A Senior Citizen | Apply rate component | Skip rate component |
| Group 1: Banking, 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 RECC-TIMESPN 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).
