One of our strange cases is: When we are creating the scenario using Connect IT, we test the connector ( SM Connector) after filled the user/password, the Test button is disabled. Or we can say its grey-out so that cannot be clicked. We have checked many times with different servers / machines, but the rootcause cannot be detected until we found that the option: Offline Mode has been switched off. What’s a cool situation!
Then, obviously, after unchecked the Offline Mode of the scenario, the button was displaying and we could test the connection now.
That’s a very cool issue that I want to share.
