Adding iview to operation giving navigation error

          Hi All Portal experts.

I am on portal version 740. I create a transactional iView.

Then I go to transactions, and create a new operation ID. I try to attach my iView to that operation ID. In the Role column, it shows - Not in navigation.

I believe that's the source of error that I finally get in my application that - No iview found for system ... object TRANS..

Any clues here guys?

Thanks.
