EOMONTH working days calculation

[Niiru1]

I have a measure to subtract the total number of days in a month e.g. 31 - absence.

Measure =

VAR _lastday =

DAY (

EOMONTH (

DATE ( LEFT ( MAX ( 'DimDate'[Month Year] ), 4 ), VALUE ( RIGHT ( MAX ( 'DimDate'[Month Year] ), 2 ) ), 1 ),

0

)

)

RETURN

IF ( ISBLANK ( [AbsentByDay] ), BLANK (), _lastday ) - [AbsentByDay]

Is there a way to only include working days in this calculation e.g. 22 working days in month - absence?

e.g. NOT WEEKDAY( 'DimDate'[Date] ) IN { 1,7 }

I have modified the formula to include only workdays, I consider weekday 1 and 7 as weekend, you can change if you need.

Measure = 

VAR _Month = 
    EOMONTH (
        DATE ( LEFT ( MAX ( 'DimDate'[Month Year] ), 4 ), VALUE ( RIGHT ( MAX ( 'DimDate'[Month Year] ), 2 ) ), 1 ),
        0
    )

VAR _lastday= 
COUNTROWS(
    FILTER(
        CALENDAR( EDATE(_Month , -1)+1 , _Month ),
        NOT( WEEKDAY( [Date] ) IN { 1,7 })
    )
)

RETURN
 IF ( ISBLANK ( [AbsentByDay] ), BLANK (), _lastday ) - [AbsentByDay]

This works great but I'm having trouble with 1 or 2 values not adding up

I think person_id 135 was absent twice in month : 201902, is there any way to account for this?

Looking into this I think the :

VAR _Month =

EOMONTH (

DATE ( LEFT ( MAX ( 'DimDate'[Month Year] ), 4 ), VALUE ( RIGHT ( MAX ( 'DimDate'[Month Year] ), 2 ) ), 1 ),

0

)

assumes that there are 30/31 days in each month?

The DimDate table has a column, Working Day, I used that as that is your basis for other measures:

Please check now:

Measure 3 = 

VAR _Month = 
    EOMONTH (
        DATE ( LEFT ( MAX ( 'DimDate'[Month Year] ), 4 ), VALUE ( RIGHT ( MAX ( 'DimDate'[Month Year] ), 2 ) ), 1 ),
        0
    )
VAR _lastday= 
COUNTROWS(
    FILTER(
        DimDate,
        DimDate[Date] >= EDATE(_Month , -1)+1 && DimDate[Date] <= _Month && DimDate[WorkingDays] = TRUE())
)    

RETURN

 IF ( ISBLANK ( [AbsentByDay] ), BLANK (), _lastday ) - [AbsentByDay]
