SAP DBTech JDBC: [258]: insufficient privilege: Not authorized

hello everyone,

I use HANA Studio ( CloudShare ) and I create a new user " DSREPO " for which I am trying to give the priviliges of " _SYS_REPO " , unfortunately I get all the time the error message:

"Could not execute ' GRANT SELECT ON SCHEMA DSREPO tO DSREPO ' in 2 ms 831 microseconds.
SAP DBTech JDBC : [258 ] : insufficient privilege : Not authorized "


I 've read here in a Tread :


1 Make sure _SYS_REPO Has SELECT privilege WITH
GRANT OPTION for the schemas used. In order to grant this privilege _SYS_REPO
you can execute the Following statement :

GRANT SELECT ON SCHEMA <YOUR_SCHEMA> TO _SYS_REPO WITH GRANT OPTION ;



2 Make sure the user activating the Object has at
least SELECT privilege over the schemas used within the scenario . SQL
statement to grant this privilege would be:

GRANT SELECT ON SCHEMA <YOUR_SCHEMA> TO <USER_THAT_WILL_ACTIVATE_ANALYTIC_OBJECT> ;

I also tried this, unfortunately it does not help.

maybe someone has an idea?

Thanks
