I would like to create a statistic in which I can see the hole time I had for a ticket. I wan't have the time between creating and closing of the ticket I just will have the hole time of all Actions in the Ticket.
After that I will create a statistic in which I can see the time of all Actions of all Ticket's from the same category (e.g. tickettype "Problem")
–> I will be able to see how many hours wee did invest overall in Problem, Auftrag, Störung etc.
How can I do that?
