How to restrict "insert new data source" in Analysis, edition for Microsoft Office report

Hi Experts,

There is a requirement in my current project: when an end user access a Analysis, edition for Office Report from BI platform, they can view and refresh the report. But users should not be able to add new data source in that Analysis Report. As per my understanding, that means "insert data source" button should remain disable for the user.

I have check all available access levels from CMC, but cannot find any. It will be great if you let know correct access level in CMC for the same.

Any comments/recommendation will be appreciated.

I am using BOXI4.1 SP3 version with Microsoft Office 2013.

Thanks in advance.

Regards,
