A named event (also known as a triggering event definition) is a custom event you create with specific attribute values. For example, a named event can check for AppManager events with a severity of Emergency and from a specific Knowledge Script. When Process Authors create triggers, they can include named events in the expressions governing when the trigger starts, suppresses, or groups a work item. For more information about triggers, see Understanding Triggers.
By default, a trigger does not require one event to meet all specified trigger expressions. A trigger requires only that one or more events meet all specified expressions within the specified time window. You can use named events in some trigger expressions to ensure Workflow Automation initiates a work item when one specific event meets all conditions. For more information about trigger expressions, see Understanding Trigger Expressions.
You can edit a named event that is not associated with a workflow revision currently in production at any time. To edit a named event associated with a workflow revision in production, you must take the workflow revision out of production. After you edit the named event, you can put the workflow revision back in production. Workflow Automation checks for updates to named events when you put a workflow revision in production. For more information about taking a workflow revision out of production, see Taking a Workflow Revision Out of Production.
