Applies To Sites
On the Event Handlers form, use this field in cases where you want an event handler to execute only when the event is triggered at certain sites.
To use this option, specify the sites where the event can be triggered. You can specify multiple sites separated with commas. If the current site is not in your list of specified sites, the event handler will not execute at the current site.
If this field is blank, the event handler can execute at any site in the database.
On the Event Handler Revisions form, this field displays the sites that were listed for the handler at the time the revision was created.
