How to do it...

To implement this recipe, perform the following steps:

1. Create a new measure with the following formula:

NetWorkDays = 
    VAR __Date1 = MAX('R10_Table'[Created Date])
    VAR __Date2 = MAX('R10_Table'[Finished Date])
    VAR __Date1a = MINX( { __Date1, __Date2 },[Value])
    VAR __Date2a = MAXX( { __Date1, __Date2 },[Value])
    VAR __Calendar = 
        ADDCOLUMNS(
            CALENDAR(__Date1a, __Date2a),
            "__WeekDay",
            WEEKDAY([Date],2)
        )
RETURN
    COUNTX(
        FILTER(
            __Calendar,
            [__WeekDay] < 6
        ),
        [Date]
    )

2. Place the NetWorkDays measure in the Table visualization created earlier.
