    Hi kyleldi,


    Firstly, create a calendar table in Power BI Desktop following the guide in this blog. Then create a column in the calendar table using the Dax below.

    is work day = SWITCH(WEEKDAY([Date]),1,0,7,0,1)

     

    Secondly, create a measure using the following DAX and create a card visual.

     

    Days= CALCULATE(SUM('Date'[is work day]),
           DATESBETWEEN('Date'[Date], 
                        [OldestDate],
                      [NewestDate]
          ))




     

    Thanks,
    Lydia Zhang

Hi,

When I try to create the measure (last step of your instructions) i get an error message: "A single value for column 'Total Revenue' in table 'SalesData' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."

 

Ho wdo i resolve that? Also are we meant to create a relationship with the Date/Calendar Table and the table containing our start and end dates?
