A trigger is a rule that causes another business process to be started. After the triggered process completes, the triggering process may either continue or terminate. The Valid Phone Number rule, for example, in the rule set Validate Input might trigger the rule set Update File.
The Triggers field for a rule identifies the rule set the rule triggers. Triggering rules are identified in the Rules pane with a symbol. A rule set can be triggered by multiple rules. A rule can trigger the rule set it belongs to.
If a rule set is triggered by a rule, the trigger is listed in the lower portion of the right-hand pane for the rule set. Double-click the name of a trigger in the list to navigate to the corresponding rule in the lefthand pane.
