Change DAX formula to Power Query formula



I have created the following DAX formula:


Workday Seconds =
VAR vWorkdayStartHour = 8
VAR vWorkdayEndHour = 17
VAR vColumn1 = bw_Cofiwerkorders[Start_werk]
VAR vColumn2 = bw_Cofiwerkorders[Datum_afgehandeld]
VAR vWorkdayHours = vWorkdayEndHour - vWorkdayStartHour
// the earlier of the two columns
VAR vStartDatetime =
      MIN ( vColumn1vColumn2 )
// the later of the two columns
VAR vEndDatetime =
      MAX ( vColumn1vColumn2 )
VAR vStartDate =
      INT ( vStartDatetime )
VAR vEndDate =
      INT ( vEndDatetime )
// count the workdays between StartDate and EndDate (non-inclusive)
VAR vWorkdaysBetween =
             COUNTROWS ( Dim_Date ),
             Dim_Date[Date] > vStartDate,
             Dim_Date[Date] < vEndDate,
             Dim_Date[WorkingDays] = 1
// total workday seconds between StartDate and EndDate (non-inclusive)
VAR vWorkdaySecondsBetween = vWorkdaysBetween * vWorkdayHours * 60 * 60
// Start Date beginning of day
VAR vStartDateBOD = vStartDate + TIME ( vWorkdayStartHour00 )
// Start Date end of day
VAR vStartDateEOD = vStartDate + TIME ( vWorkdayEndHour00 )
// End Date beginning of day
VAR vEndDateBOD = vEndDate + TIME ( vWorkdayStartHour00 )
// End Date end of day
VAR vEndDateEOD = vEndDate + TIME ( vWorkdayEndHour00 )
VAR vStartDatetimeAdj =
         SWITCH ( TRUE (),
         vStartDatetime < vStartDateBODvStartDateBOD,
         vStartDatetime > vStartDateEODvStartDateEOD,
VAR vEndDatetimeAdj =
         SWITCH ( TRUE (),
         vEndDatetime < vEndDateBODvEndDateBOD,
         vEndDatetime > vEndDateEODvEndDateEOD,
VAR vStartDateSeconds = DATEDIFF ( vStartDatetimeAdjvStartDateEODSECOND )
VAR vEndDateSeconds = DATEDIFF ( vEndDateBODvEndDatetimeAdjSECOND )
VAR vTotalWorkdaySeconds =
         SWITCH ( TRUE (),
         vStartDate = vEndDateDATEDIFF ( vStartDatetimeAdjvEndDatetimeAdjSECOND ),
         vStartDateSeconds + vWorkdaySecondsBetween + vEndDateSeconds
VAR vResult = IF ( vColumn1 < vColumn2vTotalWorkdaySecondsvTotalWorkdaySeconds * -1 )
This formula doesn't work in Power Query so I want to convert this formula to a Power Query formula. When I do this it gives me errors on CALCULATE and COUNTROWS because these two are not in Power Query.
Are there any alternatives for this part of the formula, so it works in Power Query?

@Anonymous Power Query uses M language and that is DAX so none of it is going to work. You will need to rewrite it in M. Would be very helpful to have example data and expected output from that sample data.

Sorry, having trouble following, can you post sample data as text and expected output?
Not really enough information to go on, please first check if your issue is a common issue listed here:

Also, please see this post regarding How to Get Your Question Answered Quickly:

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

@ me in replies or I'll lose your thread!!!

DAX is easy, CALCULATE makes DAX hard...
