Facing a problem with Query iView

Hi,

I am working on EP 6.0 SP7 installation of Enterprise Portal.

I am facing a problem in configuring a Query iView in the portal. After specifying the alias name of the JDBC system, while creating the iview, the next step involves specifying the Query Properties Selection, where from the system tree we choose the object properties to include in your query.

But I am unable to add the JDBC System alias into the object properties owing to which i am unable to configure the Query iView.

Can anybody who has configured the query iview help me in this please?

Regards,
