Hi All
i like SET expression to achieve above for my expression below :-
money(
sum({$<year = {$(=max(year)-1)}, month = {"<=$(=max({<year={$(=max(year))}>} month))"}>} sales/$(ColumnDim77)/1000)
, $(vMoneyFormatK_N))
The reasons for not select current month and year is create less work at initial selection.
