DE Server sends notification in form of Email or SNMP when Event triggers and runs an Application,
but no job is selected to run in the Application due to some conditions defined for the job.
Resolution:
This notification is informational to make the user aware that no job was executed in the Application for the Event trigger.
It can also be used to debug Applications and jobs that may not be running as expected.
You can suppress trigger notifications in Application properties by enabling "Suppress notification when no work selected" check box.
