Hi,
yes karthik said correct.
already you have quater you want show the report based on the month.
add the cube level 0CALMONTH,0CALMONTH2 after map the transformatons form quater to add the cube level 0CALMONTH,0CALMONTH2 then check the data in cube level.
same calmonth obejct use the report output now check the value for month wise.
Thanks,
Phani.
