If you want to get Hub State Ind of Record in Base Object, you can use following code illustration for same:

    GetRequest req = new GetRequest();

    req.setSiperianObjectUid("BASE_OBJECT.MY_BASE_OBJECT"); // Name of the BO
    RecordKey identity = new RecordKey();
    identity.setRowid("8848484");   // Rowid Object of the Record
    identity.setSystemName("SAP");  //Source System Name
    req.setRecordKey(identity);

    RecordTypes recTypes = new RecordTypes();
    recTypes.setXrefType(true);
    recTypes.setDeletedXrefType(true);
    req.setRecordTypes(recTypes);

      GetResponse res = (GetResponse) sipClient.process(req);
      String hubStateInd =null;
      List<Record> recList = res.getRecords();
      for (Record rec : recList) {
        if (rec.getSiperianObjectUid().startsWith("XREF")){
              Field field = rec.getField("HUB_STATE_IND");                
              hubStateInd = field.getValue().toString();                
        }
      }
