Cannot create transaction IView

Hi,

We are trying to create a transaction iView however the preview process consistently fails with the same error. It does not matter which transaction we use the error is the same. The user on both ABAP and Portal has full authorizations. When previewed the iView fails with the error:

An error occured in iView: N/A in component: N/A

In the logs this error is followed by the exception:

com.sapportals.portal.prt.runtime.PortalRuntimeException: iView not found::.default

This is a newly installed 7.0 portal on stack 15.

Thanks for you help.

Regards,

Colm
