Hi Gaurav,
The only way to do it would be 2 convert the GrossSales and Quantity from Column to Rows.
The way I did was to create two queries with UNION like below:-
YearMonth, GrossSales, 'GrossSales' Flag1
UNION
YearMonth, Quantity, 'Quantity' Flag2
Please note you might have to create 2 Flag objects in Universe or do custom SQL.
Then create a crosstab with below details:-
Horizontal Axis : YearMonth
Flag
Body Axis: GrossSales
Then do a sort on the Flag column. Pls refer to the screenshot on a sample I created from eFashion.
Regards,
Kashif
