Try running LIBNAME in SAS EG or PC SAS or SAS Studio or Teradata SQL Assist and check whether those views can be accessed or not. If not then something to do with access permissions for the user.
If yes then SAS VA can also read those views. Instead of typing the view names while importing try browse to see the tables or views. If your user name contains then special characters then use quotes.
Note: Make sure the server, schema and other credentials to access the views are correct.
