Authorization issue in HANA

Hello Everyone,

I have admin access and I created one user ID and tried to grant select on access to that user id to _SYS_REP user,

Executed Below SQLScript:

GRANT SELECT ON SCHEMA  "your user" TO _SYS_REPO WITH GRANT OPTION

But  when I executed the above statement it is throwing "Insufficient Previlege".

Actual issue was, I was getting authorization issue when tried to see data preview on Calculation view so I am trying to provide this access to check if it resolved that access issue.

Kindly please help me resolving this.

Thanks,

Sri
