DAX To M Query

[nirvana_moksh]

Hey All,

I had a question in regards to changing the below DAX to M and if it is possible:

CALCULATE(LASTNONBLANK('Table A'[Column 1],1),FILTER('Table A','Table A'[Index] = MIN('Table A'[Index])))

The above DAX basically finds the latest COLUMN 1 value using the Index column I have set up, I want to do this in M query so that I can limit data from right there instead of using the above DAX.

Thank You

Hi @nirvana_moksh

As tested, I add an index column from 1.

Code in Advanced Editor

let

    Source = Excel.Workbook(File.Contents("C:\Users\maggiel\Desktop\PR4.0\5\5.29\Circular dependancy.xlsx"), null, true),

    Sheet1_Sheet = Source{[Item="Sheet1",Kind="Sheet"]}[Data],

    #"Promoted Headers" = Table.PromoteHeaders(Sheet1_Sheet, [PromoteAllScalars=true]),

    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"taskId", Int64.Type}, {"startupGoalDate", type date}, {"duration", Int64.Type}}),

    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1),

    #"Added Conditional Column1" = Table.AddColumn(#"Added Index", "min", each List.Min(Table.Column(#"Added Index","Index"))),

    #"Added Conditional Column2" = Table.AddColumn(#"Added Conditional Column1","Custom", each if [Index]=[min]  then List.Last(Table.Column(#"Added Index","duration")) else null) 

in

#"Added Conditional Column2"

Something easier to do with DAX maybe complex with M query,

Reference:

List.Last

Table.SelectRows

Table.SelectColumns
