Oracle Financial Services Loan Origination uses Rule 1 and Rule 2 in the Eligibility Ruleset, each of which includes a condition (IF) statement and an action (THEN) statement.

The condition of Rule 1 specifies that none of the applicants or guarantors are under 18 and that at least one is a US citizen. The action sets the Is Eligible variable to true.

The condition of Rule 2 specifies that at least one of the applicants or guarantors is under 18 or that none are US citizens. The action sets the Is Eligible variable to false.

You can modify the existing ruleset, conditions, or actions. Take caution before modifying a condition or action, it can require source code changes. Application processing fails if this ruleset is deleted. To modify the ruleset, conditions, or actions, see "Editing Rules in an Oracle Business Rules Dictionary at Run Time," in Oracle Fusion Middleware User's Guide for Oracle Business Rules.
