BI System Integration to Portal for Visual Composer

Hi,

I am BW Consultant Working on the visual composer for the first time.

Visual Composer >New Model >Iview > BI (menu) >BI Integration Wizard

I am getting following Error

Warning 2005:There are no BI systems defined in the portal.in order to use the Bi Integration Wizard,You must first define atleast one BI system based on BI XMLA,BI ODBC,BI JDBC or BI SAP Query Connector.

But i am already publishing some BW queries in Portal using WAD...BI system is connected to porta

Please update how to proceed further.

Thanks
