i created a dashboard and now i'm working on Working Days - i added a flag on my Calendar Table , if equal to 1 is a working day if equal to 0 is non working day.
As you can see i would like to show for each region the total working day for that specific year/month; as you can see below the system is calculating the working day only if for that specific month there was a sale transaction every day. Total should be always 22 for all rows/region.
I set the expression as -> =sum({<Day=,Region=,Region_Description=,Area=,Invoice_Date=,Invoice_Date_Num=>}WorkingDay)
