Calculate Net Working Days

[manojnikam3008]

Hi Experts,

I am trying to calculate net working days between two dates that I'am capturing from slicer but somehow i am not getting the expected output.

Objective: I want to capture dates from the slicer and return net working days between that date range + i want to calculate user capacity (i.e per day working hours of user) during that date range (E.g - If user selects 10 days period in slicer, I want to return 1. Net working Days + 2. Daily working hours x 10 days = 80 + 3. I require this to calculate if user has booked 80 hours during 10 days or not -if less then i will show them Insufficient hours and vice versa)

Table name: Timesheet (62)

Column Name: Date

Column Name: 'Timesheet (62)'[IsWorkingDay]

Slicer using the [Date] Column.

Measures used: (this is done to keep it dynamic in nature upon user's selection of the specific date range)

Start date of filter = Capturing Start date of the slicer in using FIRSTDATE function
End date of filter = Capturing End date of the slicer in using FIRSTDATE function

DAX: 

WorkingDays = CALCULATE(COUNTROWS('Timesheet (62)'),DATESBETWEEN('Timesheet (62)'[Date],[Start Date of filter],[End Date of filter]),'Timesheet (62)'[IsWorkingDay]="True")

Is it allowed to use measures in this formula, if so then it's not filtering the data. I get the total of 11713 i.e. the toal of all TRUE values from [IsWorkingDay] column.

Appreciate your response on this.

Thanks in advance!

Perfect @manojnikam3008 

Rule of thumb - if your data has dates, create a date table for just this sort of thing. Glad your project is moving forward!

Got it! Thanks for this 🙂

Hi @manojnikam3008 - with a Date table this becomes really easy. 
The measure is this:

Working Days = 
CALCULATE(
    COUNTROWS('Date'),
    'Date'[IsWorkingDay] = TRUE()
)

You can then create another measure to multiply that measure by 8 or whatever to get hours.

See the file here for how this works.
You'll notice I have filtered the date slicer by valid data in the fact table:

Valid Data is just a measure that is COUNTROWS(Timesheets) - if there are records, the slicer will show it. Future and past dates though won't show up.

If that isn't what you want, please provide more specifics per the info below. But the point is with a good date dimension table, the DAX becomes very easy.
