Any ticket that you mark as 'Resolved' will be automatically archived after 24 hours. We have a dedicated tab for 'Archived Tickets', which you will not be able to unarchive but instead open a new ticket.
In Sac360°, open the archived tab, you will be able to see all archived tickets.
Once done, you can open a new ticket from your ticket archived.
In the resolved tickets, click the ticket you want and then in the right corner, click 'New ticket'.
