HI Sankar,
Please refer to this.
http://scn.sap.com/people/gitit.sagiv/blog/2011/02/22/generic-system-destination-for-the-url-iview
We provided just these properties in the http system configuration.
Host Name:xxx.yyy.com
Port: 5XX000
Protocol: HTTP
System Name: zzzz
Set the System object Permissions. We gave Read-Only permissions to the role that this iview is assigned to. (You can test with providing Read-Only access to 'Everyone').
Hope this helps.
Regards,
Reshma
