calculating QTD based on month without using ABAP logic

Hi gurus,

Can you please let me know how I can calculate QTD based on 0CALMONTH without using any ABAP logic or exit in BEx Query Designer?

When I try to use Structures in Rows to create cell restriction to calculate QTD, I am not able to add 0CALMONTH to the selection in the Structures.

Can anyone please help with these questions?

Thanks in advance.
