On the whole, OTRS is fantastic, for our helpdesk manages to handle hundreds of tickets, which would just be a nightmare without OTRS.
But the most annoying point that I face in OTRS daily is having to merge tickets.
Let me explain.
Regularly some customer sends a request to our helpdesk - and a ticket is created in OTRS - but the request is addressed to many other people too (as Cc for instance).
And it regularly occurs that one of these other people - let's call him Mr X - answers before our helpdesk has the time to tell everybody that the request is registered in our OTRS under number XXXXX. His answer creates a new ticket for the same request.
So I merge the 2 tickets, then I tell everybody about our ticket number, and ask them to keep it in the mail title.
...But, for some reason, people prefer to reply on Mr X's mail rather than mine....... which creates another ticket! ...that I have to merge to the 1st one.
And so on!
I am sure many of you experienced this annoying - and time-consuming - case, and I'd like to know how you deal with it.
I am afraid there is no (strong) solution though
