Ticket

We provide Remote Support service even on holidays and even at times when you can not use the tablet to insert the ticket, usually the customer's requirements are resolved at the time.
We noticed that inserting the ticket the next day and entering in the "open" and "close" the dates of the preceding day the ticket always returns the date of the opening day.
And 'possible to insert a ticket regarding an activity performed and closed a few days earlier without altering hours and dates of operation?

Yes. The Ticket Open/Close dates are listed under the Ticket's 'General' tab. Simple visit the fields and modify them to reflect the actual date the ticket was handled.
