Rule events can be added to a process model in one of two ways. They can either be added to the process flow as a process node, or they can be used within an activity to trigger an exception flow.
See also: Exception Flows At any time in a process model when there are certain conditions that need to be met before the process flow proceeds, an intermediate rule event should be used. Once an intermediate rule event is activated, it remains active until the rule evaluates to true.
With an expression, you can use a Rule Event to monitor global constants and process variables. Each time a global constant or process variable is changed, the rule is reevaluated.
Best Practice: As a best practice, we recommend using conditions rather than expressions whenever possible because conditions consume fewer processing resources and less memory than expressions.
The following options are available.
|Select||To perform this operation…|
|<>||not equal to|
|<=||less than or equal to|
|>=||greater than or equal to|
NOTE: Creating an expression that does not evaluate to true or false causes the expression to be automatically set to false.
