Rule specification logic in advanced mode

In advanced mode, you write your business rule in expression logic. Within an IF-THEN-ELSE conditional statement, you can use ELSEIF conditions and nest additional IF-THEN-ELSE statements.
An IF-THEN-ELSE statement uses the following format:
// Primary condition
IF <Boolean expression>
THEN <Rule Block>
// Optional – Multiple ELSEIF conditions
ELSEIF <Boolean expression>
THEN <Rule Block>
// Optional ELSE condition
ELSE <Rule Block>
ENDIF
Before you write the logic, verify that you understand the business data and the requirements of the business rule.
