Same Sales last year as per working days

[Junaid11]

Hello,
I calculated working days with the below formula.

Working Day Outcome Column =

  VAR __Date = 'Invoice Date'[InvoiceDate]

  VAR __WeekDay = WEEKDAY(__Date,2)

  VAR __MonthStart = DATE(YEAR(__Date),MONTH(__Date),1)

  VAR __NetWorkDays = NETWORKDAYS(__MonthStart, __Date)

RETURN

  IF(__WeekDay < 6, __NetWorkDays,BLANK())

It is working perfectly fine. Now I want to calculate sales for same period last year based on these working days like if 1st working day of october 2022 is 3000 then what would be of 1st working day of October 2021. I was using sameperiodlastyear butit takes date instead if day. How can I use these working days as comparison, Your help would be highly appreciated.
Thank you

Hi @Junaid11 ,

You can try this method:

I create two tables as the sample data:

In the Invoice Data table, new some columns:

Sales = CALCULATE(SUM(Sales[Sales]), FILTER('Sales','Sales'[Date] = 'Invoice Date'[InvoiceDate]))

Month = MONTH('Invoice Date'[InvoiceDate])

Year = YEAR('Invoice Date'[InvoiceDate])

LastYearWorkDaySales =
CALCULATE (
    SUM ( 'Invoice Date'[Sales] ),
    FILTER (
        'Invoice Date',
        'Invoice Date'[Month] = EARLIER ( 'Invoice Date'[Month] )
            && 'Invoice Date'[Year]
                = EARLIER ( 'Invoice Date'[Year] ) - 1
            && 'Invoice Date'[Working Day Outcome Column]
                = EARLIER ( 'Invoice Date'[Working Day Outcome Column] )
            && NOT ( ISBLANK ( 'Invoice Date'[Working Day Outcome Column] ) )
    )
)

The result is:

Hope this helps you.
