Hi,
Sorry for the number.In office I am very used to put signature like this. 
By any chance can I edit my post,? And yes I am learning HANA of my own. I am a ABAPer by profession.
And yes coming on the query I created graphical calculation view like below.
And I have given join type as left outer join but I only want entry which does not exists in Table4.
Can it be achieved with the help of graphical view? Or shall we have to use SQL script for the same?
BR
