Hi,
I upgraded our HANA System from 1.0. SP9 (R. 090) to 1.0 SP10 (R. 102).
We had a lot of Warning with some DUs:
...

I tried to reimport the DU manually: same
Our HANA System running but the DBA Cockpit can't runs after the login page. We have the error: Unable to load groups
-> started from DBA studio or directly with the link (http://<HANABOX>:<PORT>)/sap/hana/admin/cockpit)
I found some Notes but not resolve my Problem...
I see that a lot of Privileges not imported
If i compare the Schema _SYS_RT from our HANA System with another HANA System (1.00 R. 102), there a lot of tables missing...
see attach file (our _SYS_RT schema)
Our HANA System is in Production Internally for some Project... (we have installed it there are 3 years ago with 1.00.28 and some upgrade and migration... )
Could i import the Schema _SYS_RT from another HANA System with same Release (fresh install) ?
Do you have more idea?
Thanks for advance for your help 
Best regards,
Rico
