iView Preview Error - Portal Runtime Error

Hi Guys,

I created an ABAP webdynpro application and was able to test in SE80. I created an iView and when I preview it, I am getting below error:

Portal Runtime Error

An exception occurred while processing a request for :

iView : N/A

Component Name : N/A

Unable to lookup System 'mgsap_r3'. Please check the system object and the alias..

See the details for the exception ID in the log file

Please guide me to resolve this error.

Thanks,

mini
