there is a fixed condition in Service Desk, that you cannot change: you cannot skip more than one status automatically. You already "jumped" over the Open status and want to skip the next status too. As far as I know that works as designed.
So either you redesign your process to do without the grey status, or you add a manual action that can be scheduled. The schedule has the disadvantage of a delay up to an hour (because the minimum interval of the schedule is 1 hour), but you can execute the manual action automatically when the schedule runs.
Hope I could be of help!
Thanx a lot for your response Andreas !
I will try the solution of the scheduled action, the delay is not a problem in my case.
