I need to create a custom rule that doesn't allow to save the ticket if the field "Impact" is equal "N/A".
I came up with Query:
(( HD_IMPACT.NAME = 'N/A') and HD_TICKET.HD_QUEUE_ID = 6 )
But I am not sure in the Update query to not allow to save the ticket and warn that the field "Impact" is required. Is there a way to do from a custom rule or the only way is through custom field?
