Hi Prasad,

You can use API to Navigates the WTDocumentUsageLink. It returns QueryResult of WTDocumentMaster.

QueryResult qr = WTDocumentHelper.service.getUsesWTDocumentMasters(doc);

Below is sample code snippet for your reference.

  ObjectIdentifier oid = ObjectIdentifier.newObjectIdentifier("wt.doc.WTDocument:314514");
  WTDocument doc = (WTDocument) PersistenceHelper.manager.refresh(oid);
  QueryResult qr = WTDocumentHelper.service.getUsesWTDocumentMasters(doc);


  while (qr.hasMoreElements()) {
         WTDocumentMaster master = (WTDocumentMaster)qr.nextElement();
         WTDocument latest = (WTDocument)wt.vc.VersionControlHelper.service.allVersionsOf(master).nextElement();
         System.out.println("Identity -> " + latest.getDisplayIdentifier().getLocalizedMessage(Locale.ENGLISH) + " & State -> " + latest.getState());
  }

I hope this helps you.
