Hi,
What I have told in previous thread is,
1. Create New Analytic privilege with SQL Type.
2. In this Analytic Privilege, Add your Attribute View and Apply Restriction Condition on required column. Save and Activate this SQL Analytic privilege.
3. Apply this SQL Analytic Privilege to the User which you are using to check the Data Preview.
4. Then Using this User, you can able to see the Data Preview of Attribute View successfully.
