Hi Smita,
Please follow the below steps to hide the user profile iView fields:
1. Login to the Portal with Administrator Id.
2. Browse Portal Content --> Content Provided by SAP --> End User Content --> Standard Portal Users --> Every User Core Role.
3. Open the Role and follow the screenshots.
Click on Preview button. I’ve already removed the fields (First Name and Last Name). Hence, they are not visible.
Right click on the page and click on Settings for Current role.
Hope this helps!!!
BR,
Anurag
