HI, 

what do you want to achieve with above exp? Could you pls elaborate a bit more.

Can use below expressions for CYTD & PYTD.

CYTD;

Sum({<={>=$(=Date(YearStart(Max(Date)))) <= $(=Date(max(Date)))}>}Sales)

CYTD;

Sum({<={>=$(=Date(YearStart(Max(Date),-1))) <= $(=Date(addyears(max(Date),-1)))}>}Sales)

Thanks,
