Step 1: Register the Event

• Open System Policy -> Events -> Registry
• Select New
• Register the Event

Event name - name used in script logic to generate the event. By convention the event name is <table name>.<event name>. The table_name is not automatically added to the Event name and must be added manually.
Table - database table for the event.
Fired by - list of scripts calling this event. This is used for troubleshooting only and not for event processing. Whenever you add an event to a script, update this field.
Description - documents the event purpose. Be sure to put a meaningful description for future reference. If you alter the meaning of an event, update this field.
Application - identifies the scope containing the event.
Queue - the event processing queue which manages this event. If left blank, the event is processed by the default queue. User-defined queues should be all lowercase and use underscores to separate words.

ServiceNow cannot respond to events unless they have been registered. The method used to generate events can be passed any string as the event parameter. Events generated with unregistered event names wil be inserted in the event queue but no ServiceNow processes will respond to the event queue entry.
