Adding a ConditionLocate this document in the navigation structure

Context

You add conditions to a rule when you want the associated actions in the rule to be performed only when the conditions are satisfied.

For more information, see Rule

Example

Consider the rule:

If

  
 

Student aggregate score greater than or equal to 60

Then

Display message equals "This student qualifies."

In this rule the condition is that the aggregate score must be 60% and above. Only if this condition is fulfilled he student is considered qualified.

Conditions are always of the format: "LHS value comparator RHS value". In the rule editor, under the If section of a rule you can specify the LHS value and RHS value and choose an appropriate comparator.

Procedure

  1. Locate the ruleset , expand the ruleset node, the Rules folder and double-click a rule node.

    or

    Locate the flow ruleset , expand the flow ruleset node, the Rules folder and double-click a rule node.
