Hi Praven,
just right click an object on the diagram for example. Select "Impact and lineage analysis" in the following dialog you may
choose "Generate Diagram"
In the data movment model, create a "transformation process" , right click that process and add a "transformation task" and close
the dialog.
By right clicking the "transformation process" and selecting open diagram, you may define the task by "ETL" tools.
Rgds, Andreas
