Hello I have the following situation:
used the following set Analysis:
sum ({$} <Month_Sale = {$(=month(addmonths(max(Date_Sale), -1)))}> Qty)
By using the expression above it works correctly when the selection year is exergar filter to the data of the previous month, my problem happens when I select the month of January because this expression brings zeroed data, how can I resolve this situation? thank you
