Ulrich,
I'm using a SAP Cloud Appliance Library instance of the "SAP NW AS ABAP & SAP BW 7.40 SP8 on HANA" Solution.
Just as you wrote your lates post, I terminated the instance 
I will try to create a new one and see if the problem still exist after doing the initial configurations.
Also, this time I will update the CC.
Regards,
Magnus
