Added User == zoho.loginuser

Added User == zoho.loginuser

When i try to add criteria to the report
Added User == zoho.loginuser
After that I don't see any date of the view
want to give my customers a report based on data they has already entered and will enter but this method don't work

And another problem,
zoho.appuri returns my workspace name zoho_ill1 (with 1 of the end and zoho_ prefix) but link of application is https://creator.zoho.com/userhome/zoho_ill/dashboard
Why ? And how to change this workspace name?

And how i can use roles in Customer portal ?
Thanks !
