Description |
|---|---|
Not |
Select to create a negative condition. |
Left ( and Right ) |
Select the left and right parentheses to group conditional clauses within the rule. |
Variable ID |
Each rule condition has two Variable ID fields. In the first one, select the variable that the system evaluates to determine whether the condition is true. Make sure that the variable will be set by the time the system evaluates the rule. To compare the first variable to another variable, select a value in the second Variable ID field. Leave the second Variable ID field blank if the system compares the first variable to a constant. |
Operators |
Select an operator to evaluate the variable in the first Variable ID field. The following comparison operators are available: equals, does not equal, is less than, is less than or equal to, is greater than, is greater than or equal to. |
Bind Value |
To compare the variable in the first Variable ID field to a constant, leave the second Variable ID field blank and enter the constant in the Bind Value field. |
Use the Rule Set page (RC_RULESET_PG) to group rules that are used together in a script tree.
