Hi, There is a command line tool in OTRS 4 for deleting tickets: otrs.TicketDelete.pl - delete tickets by number. Copyright (C) 2001-2016 OTRS AG, http://otrs.com/ Usage: otrs.TicketDelete.pl [options] Options are as follows: --help display this option help --TicketNumber no1 no2 no3 delete listed tickets (by ticket number) --TicketID no1 no2 no3 delete listed tickets (by ticket id) $ perl otrs.TicketDelete.pl --TicketNumber 2015120616000016 2016020116000015 Deleting specified tickets... 2 tickets have been deleted. In OTRS 5 there is also a command line tool to delete tickets: perl otrs.Console.pl Maint::Ticket::Delete --help Delete one or more tickets. Usage: otrs.Console.pl Maint::Ticket::Delete [--ticket-number ...(+)] [--ticket-id ...(+)] Options: [--ticket-number ...(+)] - Specify one or more ticket numbers of tickets to be deleted. [--ticket-id ...(+)] - Specify one or more ticket ids of tickets to be deleted. [--help] - Display help for this command. [--no-ansi] - Do not perform ANSI terminal output coloring. [--quiet] - Suppress informative output, only retain error messages. This is not work: perl otrs.Console.pl Maint::Ticket::Delete --ticket-number 2016032344000018 2016022644000041 Error: found unknown arguments on the command line ('2016022644000041'). But this works: perl otrs.Console.pl Maint::Ticket::Delete --ticket-number 2016032344000018 --ticket-number 2016022644000041 Deleting tickets... 8 5 2 tickets have been deleted. Why is it neccessary to set --ticket-number several times? Why doesn't work with a list of ticket numbers separated by space or something other separator? Regards, Balázs
