Hana Studio Object Privileges

Hi Experts,

I have two users other than systm user in hana studio (created by implementation partners team members and they assigned full access on (_SYS_BIC) in Object Privilege and as a result user can see all calculation views for any data base, I found this mistak and I gave access on specific calculation view to user, It's working in Power BI but when my team trying to refresh in Excel it's giving an error.

Can anyone please suggest me what i am missing.
