Hi Sridhar,
wyh do you need all this informations in a single data source? A usual way would be to create additional datasources for DFKKSUMC and DFKKK0. And then to combine the data in SAP BW in a proper data model.
As you did not specify the required data model in detail it is difficult to tell wether it is possible to add the additional tables in the datasource.
