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
Solved! Go to Solution.
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,
