Symptoms

When a user with snc_external role navigates to Service Portal, they get the error "Security constraint prevent access to requested page".

Release

All releases

Cause

One of the reasons this could happen is if the $sp page is set to non-public in Public Pages [sys_public] table. 

This means that the Active checkbox on $sp is unchecked in sys_public table. 

Resolution

1. Navigate to sys_public.list in the filter navigator.
2. Look for Page: $sp
3. Make Active = true
4. Save.
