I have not found a way to specify a closure code when setting a request to closed. How can I do this, e.g. add a closure code "can not be reproduced"? (I have defined them in the Settings -> Helpdesk -> Request Closure Code.)
Thank you for enlightening me ;-)
PS: Sorry, I posted this in the wrong category. If someone with sufficient rights moves this away from Announcements, I'll be happy. I just don't want to delete it, in case someone else wonders about the same issue.
