[paulyeo11]

Hi All

I have below expression work fine :-

Sum({<year = {$(=Max(year) - 1)} , month = {"<=$(=Max({<year={$(=Max(year) - 1)}, sales = {'*'}>} month))"}, rEVENUE={"rEVENUE"} >} Amount*1)/Rate/1000

I try to add sum(aggr into above expression :-

sum(aggr(

Sum({<year = {$(=Max(year) - 1)} , month = {"<=$(=Max({<year={$(=Max(year) - 1)}, sales = {'*'}>} month))"}, rEVENUE={"rEVENUE"} >} Amount*1)/Rate/1000

))

it display null value.
