Hi,

For creating User Criteria for Portal:

1. In the navigation filter, type Service Portal.
2. Select a page, widget, or widget instance record.
3. In the related list at the bottom of the record, select the Can View or Cannot View tab, then click New. If a user criteria record is already created, you can click Edit to apply user criteria to the page, widget, or widget instance.

   User criteria records are stored in the user_criteria table.

   

4. Complete the fields on the form, as appropriate.
5. Submit

Mark my answer correct & Helpful, if Applicable.

Thanks,

Sandeep
