I have installed and setup NWDS 7.1 ehp1.
I am able to connect to enterprise services registry as well.
However all the required wsdl that I want to import like CommunicationChannelService are under external definitions of http://sap.com/xi/XI/System and not under service interface. and hence when I go to file >> import >> wsdl >> enterprise services registry I do not see them.
Does that mean importing from WS navigator or download wsdl and import as a file are my only options?
