If you have successfully created the ticket, the ticket ID appears in the Last Comment column in the Event Details for the incident and in the Ticket ID column. If the Web console settings are configured and enabled, the ticket ID appears as a link to the ticket page in Service Desk.
For tickets that were created manually, you cannot manually update the ticket using the CA Service Desk Connector. You need to manually update the ticket in Service Desk for any subsequent incident severity change.
