What I am trying to do is to restrict some of the fields on the form from Customer Portal user but not from Internal User.

What I anticipate is if there is a system variable like "zoho.loginuser" for only customer portal user something like "Zoho.Customer_portalUser" which variable only holds customer portal user and exclude internal user .. Not sure something like zoho already has ?

I know a workaround that I have to create a form for all internal user and list of of that and use that form data on IF Condition. But that is not something automated as I have to enter each time new user once we got new internal user 

Can any one help me for better automation ?

Thanks
