KACE Product Support

Currently have the below rule working for sending email to a group when a new ticket is created. IT has found that we would like to log tickets for ourselves to work on but would prefer that when we open tickets for ourselves, the standard email doesn't go to our whole IT group like it does currently for all tickets. There's no need for everyone else to be aware that you logged a ticket with yourself as the owner from the start.

    WHERE
     C.DESCRIPTION LIKE '%CREATED%'
      /* this is necessary when using group by functions */
    GROUP BY HD_TICKET.ID
    HAVING 1=1

I thought it would be as simple as changing the WHERE to something like this:

WHERE
     C.DESCRIPTION LIKE '%CREATED%' AND
     SUBMITTER.USER_NAME <> OWNER.USER_NAME

But when I add that additional condition, it no longer sends emails at all, even when there is no owner assigned when the ticket is submitted. Anyone know how to accomplish this?
