Power Query WORKDAY?

Hi

Is there a Power Query version of the excel formula WORKDAY?

I need to filter a report based on the previous working day, and I can use 'Day>Yesterday' in the filter options, however, if the report is run on a Monday this will show Sunday when it needs to show the Friday.

=workday(today(),-1) does this but I can't see a Power Query version.

Am I just missing it?

thanks
Barry

Here a solution

PHP Code: 

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    cType = Table.TransformColumnTypes(Source,{{"Val", Int64.Type}, {"Date", type date}}),
    getPrevWorkday = Table.SelectRows(cType, each [Date] = List.Last(List.Select(List.Dates(Date.AddDays(Date.From(DateTime.FixedLocalNow()) ,-3),3,#duration(1,0,0,0)), (x)=> Date.DayOfWeek(x,1)<5)))
in
    getPrevWorkday 


Here a shorter version

PHP Code: 

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    cType = Table.TransformColumnTypes(Source,{{"Val", Int64.Type}, {"Date", type date}}),
    getPrevWorkDay = (varDate as date) =>
        let
            wkDay = Date.DayOfWeek(varDate, 0),
            prevWorkDay = Date.AddDays(varDate, {-2,-3,-1,-1,-1,-1,-1}{wkDay} )
        in
            prevWorkDay,
    result = Table.SelectRows(cType, each [Date] = getPrevWorkDay(Date.From(DateTime.FixedLocalNow())))
in
    result
