Issue in service composer perspective in nwds

Hi All,

We are creating a composite service using service composer perspective .we use nwdi for versioning and deployment.

The service reference /service group stopped appearing in the activity and the connectivity information on the project also disappeared project context . The issue is we are not able to generate the code after mapping is done

We were able to generate this till few days back and it has suddenly stopped working.  we are able to create a new dc and we dont have any issues there.

Any idea on the same or any known issues with nwds.

AP PO 7.31 Ehp6 .

Nwdi is on 7.02

Thanks,

Rajesh
