Hi Venkat,
Thank you for your reply.
I am using webi 4.0 and connecting to BEx query using BICS connection.
issue is, in above mentioned scenario: when there are no C,D materials (for some filters) then GroupB is not dispaying.
But I am expecting both GroupA and GroupB in X axis (GroupB should be 0 as there are no listed materials C, D).
Thank you again,
