At the moment if a ticket is going to be saved we have the following options:
If I change the settings = Setup\Tickets\Options\Enable TicketE-ail Overrides I get the additional options:
Certainly doing this will give me full control of who is getting what information. But I hoped that there is a global setting in the background to change this.
I just wanted to ensure that if we send an e-mail out of WHD to a supplier that the response will be added into the ticket, but in this case no e-mail should be send by WHD to the client about the suppliers ticket update.
