As there is no standard functionality for this Data preview and sub-node level functionality.
We provided the work around as if Business Analysts observe such privilege issue in any of the HANA views, they can copy the View to a different package (non-usable package) and activate the new HANA view.
That way the Business Analyst becomes the owner of the new View created and he/she can perform the Data Preview at sub-node level.
Thanks,
