Hey Shankar,
You can do this in the entity properties (Access roles) tab,
There you can define different access rules for each user,
There you can restrict users to see their own data only by writing the XPath:
[System.owner='[%CurrentUser%]'] (Don’t forget to check the ‘Store Owner’ option ),
and allow the admin to see the data of all the other users,
Let me know if you face any issues,
Hope it helps!
