Circumstance specialization in Pega LSA mission
Example cited for circumstance is as below.
"For instance, consider a loan approval application that offers different interest rates based on the customer's credit score. Instead of creating separate Rules for each credit score range, you can use circumstance specialization to create variations of the base Rule.
Create a base Rule that calculates the interest rate for a loan. Circumstance the base rule by using the property CreditScore. Create specialized Rules for different credit score ranges, such as:
- Circumstance 1: If 'CreditScore' is between 300 and 579, set the interest rate to 10%.
- Circumstance 2: If 'CreditScore' is between 580 and 669, set the interest rate to 8%.
- Circumstance 3: If CreditScore is between 670 and 739, set the interest rate to 6%. "
Is this a valid example for circumstance ? Above requirement can be easily implement using decision table, right?
Please advise.

Define conditional rule variants—such as flows, decision tables, or UI sections (UI sections are not supported in Constellation)—based on property values, dates, or combined criteria, instead of relying on complex if-else logic. For example, cases created before 2025 use the path in the base flow rule, while cases created after 2025 follow the new workflow path.
Another example: For loan applications, if ApplicationDate is before 2026-01-01, use the legacy credit scoring decision table (base version) and the base underwriting flow. If ApplicationDate is on or after 2026-01-01—or Applicant.Region = "EU"—use the updated decision table (circumstanced version).
