Distinct count with datediff between column date and selected date value

[Anonymous]

Hi Team,

I am new to Power BI and is currently working on a calculation which I cannot figure out.

I am trying to count distinct number of employees from a fact table using the following calculated measure. 

employee_count_90days = calculate(distinctcount(employees[employee#]), FILTER(employees, employee_status = "Active" && DATEDIFF(employees[hire_date],selectedvalue(calendar[Date]),DAY) > 90))

What I need is to exclude the weekends from the calculation between the hire_date column and the selected date from the calendar slicer. 

Hoping for someone to help.

Hi @Anonymous ,

According to your description, two additional filters need to be added to exclude weekend dates. Refer to a similar test.

employee_count_90days =
CALCULATE (
    DISTINCTCOUNT ( employees[employee#] ),
    FILTER (
        employees,
        DATEDIFF ( employees[hire_date], SELECTEDVALUE ( calendar[Date] ), DAY ) > 90
            && employees[Col_week] <> 7
            && employees[Col_week] <> 6
    )
)

Col_weekday = WEEKDAY('employees'[hire_date])

If the problem is still not resolved, please provide detailed error information and test data. Looking forward to your reply.

Best Regards,
Henry

Hi @v-henryk-mstf 

Thanks for the answer.

What we need is date difference between employee hire date and selected calendar date but excludes the weekend from the calculation between the 2 dates. Something like below and the calendar table is not connected to fact table.

employee_count_90days = calculate(distinctcount(employees[employee#]), FILTER(employees, employee_status = "Active" && DATEDIFF(employees[hire_date],selectedvalue(calendar[Date]),DAY) - (**weekends between the hire date column and slicer selected date ) > 90))

Hi @Anonymous ,

It is not yet clear, is it possible to provide test data and screenshots of the expected results?

Best Regards,

@Anonymous , Hope calender date is joined with hire date , in hat you need work day rank and use that for last 90 work day

Work Day = if(WEEKDAY([Date],2)>=6,0,1)
Work Date = if(WEEKDAY([Date],2)>=6,BLANK(),[Date])
Work Date Cont = if([Work Day]=0,maxx(FILTER('Date',[Date]<EARLIER([Date]) && [Work Day]<> EARLIER([Work Day]) ),[Date]),[Date])
Work Date cont Rank = RANKX(ALL('Date'),[Work Date Cont],,ASC,Dense)

employee_count_90days = calculate(distinctcount(employees[employee#]), FILTER(employees, employee_status = "Active" ), filter('calendar',  DATEDIFF('calendar'['Work Date Cont'],selectedvalue(calendar[Work Date Cont]),DAY) > 90))

Hi Amitchandak,

Thanks for this however my calendary table is not connected to the fact table.

Would there be a solution for this scenario?

I appreciate your big help!
