Creating a networkdays type of measure

[water-guy-5]

I already have a Dimension Dates table and one of the columns looks like this
    Day       DayofWeek
Sunday           1
Monday          2
Tuesday          3
Wednesday    4
Thursday        5
Friday             6
Saturday         7

I have a measure that return if a day is a weekday like this:

IsWeekday = IF(OR(DimDates(DayofWeek) = 1, DimDates(DayofWeek) = 7), "Yes", "No")

I am now trying to use DATEDIFF to calculate the time between two columns. 'ScheduledDate' and 'CompletedDate'.

Thanks!

Hi @water-guy-5 

If you want a calculated column, here is an example. See Counting working days in DAX - SQLBI

Sales[DeliveryWorkingDays] =
CALCULATE(
    COUNTROWS ( 'Date'),
    DATESBETWEEN ( 'Date'[Date],  Sales[Order Date], Sales[Delivery Date] – 1 ),
    'Date'[IsWorkingDay] = TRUE,
    ALL ( Sales )
)

Take notice that when using DATESBETWEEN(<Dates>, <StartDate>, <EndDate>), if StartDate is larger than EndDate, the result is an empty table. So you may need to add an IF condition to decide which date ('ScheduledDate' and 'CompletedDate') is larger before calculating net working days.

@water-guy-5,

You may want to double check your IsWeekday measure.  It looks to me like you have your YES and No reversed.

If Weekday = 1 or 7, then it is a Weekend, not Weekday.  Just wanna make sure you get this part correct.

Hi @water-guy-5 
You could do something like this basicly counting the rows in the DimDate table with the filters applied. 

This function includes both the first and last day. But your business requirement might be different. But that can easily be changed in de variables.

Working days = 
VAR startdate = MAX(Table[ScheduledDate])
VAR enddate = MAX(Table[CompletedDate])
RETURN

CALCULATE(
    COUNTROWS('DimDate'), 
    DATESBETWEEN('DimDate'[Date], startdate, enddate),
    'DimDate'[DayOfweek] > 1 && 'DimDate'[DayOfweek] < 7)

Best regards
jeroen,
