Am I missing something? there appears to be no way to do this. I need to delete a tracking number field from an Order Custom Object. It allows me to edit it but does not allow me to delete. The problem is that its not a one to one relatioship. So I created a tracking object and made it a related list. That works fine but its not giving me any option to delete the old custom field that was existing before and now useless to the application.
