Sort Dim Date descending without a circular dependency

Hi Anonymous ,

I suggest you to create a Calendar table in Power Query Editor and add an index to sort [Date] column.

For reference: Create Calendar Table Using Power Query M Language

let
    Source = Excel.Workbook(File.Contents("C:\Users\...\Desktop\Sample.xlsx"), null, true),
    Sheet2_Sheet = Source{[Item="Sheet2",Kind="Sheet"]}[Data],
    #"Promoted Headers" = Table.PromoteHeaders(Sheet2_Sheet, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Date", type date}, {"Value", Int64.Type}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"Date", "RECORD_DATE"}}),
    RECORD_DATE1 = #"Renamed Columns"[RECORD_DATE],
    #"Converted to Table" = Table.FromList(RECORD_DATE1, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Filtered Rows" = Table.SelectRows(#"Converted to Table", each ([Column1] = List.Min(RECORD_DATE1))),
    #"Renamed Columns1" = Table.RenameColumns(#"Filtered Rows",{{"Column1", "Start Date"}}),
    #"Added Custom" = Table.AddColumn(#"Renamed Columns1", "End Date", each Date.From(DateTime.LocalNow())),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Date", each {Number.From([Start Date])..Number.From([End Date])}),
    #"Expanded Date" = Table.ExpandListColumn(#"Added Custom1", "Date"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Date",{{"Date", type date}}),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"Start Date", "End Date"}),
    #"Sorted Rows" = Table.Sort(#"Removed Columns",{{"Date", Order.Descending}}),
    #"Added Index" = Table.AddIndexColumn(#"Sorted Rows", "Index", 1, 1, Int64.Type)
in
    #"Added Index"

Result is as below.
