How to add Index Column based on date condition

Hello All,

 

I have a below table

DateNumber
2/3/2023 12:00:00 AM160
4/14/2023 12:00:00 AM161
5/16/2023 12:00:00 AM162

6/23/2023 12:00:00 AM

 

163
7/23/2023 12:00:00 AM164
9/26/2023 12:00:00 AM165
10/20/2023 12:00:00 AM166
11/3/2023 12:00:00 AM167

 

I need to create an index starting from 1 if [Date]>today() otherwise negative index or null values.

 

Expected Result:

 

DateNumberIndexIndex
2/3/2023 12:00:00 AM160null-4
4/14/2023 12:00:00 AM161null-3
5/16/2023 12:00:00 AM162null-2
6/23/2023 12:00:00 AM163null-1
7/23/2023 12:00:00 AM164null0
9/26/2023 12:00:00 AM16511
10/20/2023 12:00:00 AM16622
11/3/2023 12:00:00 AM16733

 

Tried below logic but its creating 53 rows for each date starting 9/26/2023 and adding index from 1 to 53 for each date and repeating that pattern for all dates starting from 9/26/2023.

 

Index= Table.AddColumn(#"Changed Type", "Custom", each if [Date]>DateTime.LocalNow() then Table.AddIndexColumn(#"Changed Type", "Index", 1, 1,Int64.Type) else null)

 

Can you please let me know how to achieve the above result. I am able to achieve this using dax but I need this in Query editor not in DAX.

 

Thank you!

@ashuaswinireddy here is one way, start a blank query -> advanced editor and paste the M code below, change it as you see it.

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("dc87CoAwEEXRrYSpA/PJD+0EW91ASKGQ0kZ0/4axTWC6c3kwOcN6PBUs7O911huKzSDoUEicYZmJ2pllawVHUvbIvu+sHpBj30W94WDfqaehe/UJZbAf1Jma9oP4Bzx6MEEpHw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"(blank)" = _t, #"(blank).1" = _t]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"Date", type datetime}, {"Number", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type1", "Custom", each if [Date]>DateTime.LocalNow() then "More" else "Less"),
    #"Grouped Rows" = Table.Group(#"Added Custom", {"Custom"}, {{"All", each _, type table [Date=nullable datetime, Number=nullable number, Custom=text]}}),
    #"Added Custom1" = Table.AddColumn(#"Grouped Rows", "Custom.1", each if  [Custom] = "Less" then Table.AddIndexColumn([All],"Index" ,Table.RowCount([All])*-1,1) else Table.AddIndexColumn([All], "Index", 0,1)),
    #"Expanded Custom.1" = Table.ExpandTableColumn(#"Added Custom1", "Custom.1", {"Date", "Number", "Index"}, {"Date", "Number", "Index"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Custom.1",{"Custom", "All"})
in
    #"Removed Columns"
