Through the "Status" link in the admin area of OTRS you can manage the
different states you want to use in the ticket system.
After a default setup the states "closed successful",
"closed unsuccessful", "merged", "new", "open", "pending auto close+",
"pending auto close-" "pending reminder" and "removed" are already
installed in the system. Every state is linked to a state type that needs
to be specified if a new state is created. Per default the state types
"closed", "merged", "new", "open", "pending auto", "pendig reminder" and
"removed".
