Push notification through netweaver gateway

Hi ,

I am using this link,

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e03df0bf-a783-2e10-eca8-9e4918fd37ee?QuickLink=index&overridelayout=true&51492363279729

to perform the push notification process through Gateway .

In this document ,

At step 4.3.5 , in point number 2 , I am not at all getting the right hand side pane , eventhough i have created all the previous said steps correctly.

As I doouble click the GW data model , I am getting error saying like below:

Data Object ZASW_BUS1001_0001_PS       ZN72E320E5 does not exist

Please guide me . I am working on this error for a very long period of time.
