    Hi jeamps01 

     

    Download example PBIX file

     

    This query does it

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQ31DcyMDJU0lEyNDBVitVBEzJGF7LAUGQJETFC1maOKWSBLmSJKWKmFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Index = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Index", Int64.Type}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index.1", 0, 1, Int64.Type),
    #"Sorted Rows" = Table.Sort(#"Added Index",{{"Date", Order.Ascending}, {"Index", Order.Descending}}),
    #"Grouped Rows" = Table.Group(Table.Buffer(#"Sorted Rows"), {"Date"}, {{"Count", each _, type table [Date=nullable date, Index=nullable number, Index.1=number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each Table.AddIndexColumn([Count], "Index.2", 1, 1, Int64.Type)),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Count"}),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Removed Columns", "Custom", {"Index", "Index.1", "Index.2"}, {"Index", "Index.1", "Index.2"}),
    #"Sorted Rows1" = Table.Sort(#"Expanded Custom",{{"Date", Order.Ascending}, {"Index.1", Order.Ascending}}),
    #"Removed Columns1" = Table.RemoveColumns(#"Sorted Rows1",{"Index.1"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns1",{{"Index.2", "Ranking"}})
in
    #"Renamed Columns"

Hi jeamps01 ,

Only need two steps:

step1,group and add inex:

 

 

= Table.Group(Source, {"Date"}, {{"Partition", each Table.AddIndexColumn(_, "Ranking",1,1), type table}})

 

 

Step2, expand table:

 

 

= Table.ExpandTableColumn(Partition, "Partition", {"Index", "Ranking"}, {"Index", "Ranking"})

 

 

All power query:

 

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQ31DcyMDJU0lEyNDBVitVBEzJGF7LAUGQJETFC1maOKWSBLmSJKWKmFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Index = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Index", type number}}),
    Partition = Table.Group(Source, {"Date"}, {{"Partition", each Table.AddIndexColumn(_, "Ranking",1,1), type table}}),
    #"Expanded Partition" = Table.ExpandTableColumn(Partition, "Partition", {"Index", "Ranking"}, {"Index", "Ranking"})
in
        #"Expanded Partition"

 

 

Output result:

 

Accord you provided ,change to the below:

 

let
    Source = SharePoint.Files("XXX", [ApiVersion = 15]),
    #"Filtered Rows" = Table.SelectRows(Source, each ([Folder Path] = "XXX")),
    #"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", let latest = List.Max(#"Filtered Rows"[Date created]) in each [Date created] = latest),
    #"Filtered Hidden Files1" = Table.SelectRows(#"Filtered Rows1", each [Attributes]?[Hidden]? <> true),
    #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File (6)", each #"Transform File (6)"([Content])),
    #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File (6)"}),
    #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File (6)", Table.ColumnNames(#"Transform File (6)"(#"Sample File (6)"))),
    #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table Column1",{{"Source.Name", type text}, {"Census#", Int64.Type}, {"DateTY", type text}, {"PropSupTY", Int64.Type}, {"PropDemTY", Int64.Type}, {"PropRevTY", Int64.Type}, {"CompSupTY", Int64.Type}, {"CompDemTY", Int64.Type}, {"CompRevTY", Int64.Type}, {"OccRankTY", type text}, {"ADRRankTY", type text}, {"RevParRankTY", type text}}),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type",{"Source.Name"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Removed Columns",{"DateTY", "Census#", "PropSupTY", "PropDemTY", "PropRevTY", "CompSupTY", "CompDemTY", "CompRevTY", "OccRankTY", "ADRRankTY", "RevParRankTY"}),
    #"Inserted Suffix" = Table.AddColumn(#"Reordered Columns", "Suffix", each [DateTY] & "01", type text),
    #"Changed Type1" = Table.TransformColumnTypes(#"Inserted Suffix",{{"Suffix", type date}}),
    #"Reordered Columns1" = Table.ReorderColumns(#"Changed Type1",{"Suffix", "DateTY", "Census#", "PropSupTY", "PropDemTY", "PropRevTY", "CompSupTY", "CompDemTY", "CompRevTY", "OccRankTY", "ADRRankTY", "RevParRankTY"}),
    #"Renamed Columns" = Table.RenameColumns(#"Reordered Columns1",{{"Suffix", "Date"}}),
    #"Removed Columns1" = Table.RemoveColumns(#"Renamed Columns",{"DateTY"}),
    #"Changed Type2" = Table.TransformColumnTypes(#"Removed Columns1",{{"Census#", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type2", "Index", each ([PropRevTY]/[PropSupTY])/([CompRevTY]/[CompSupTY])),



    #"Changed Type3" = Table.TransformColumnTypes(Source,{{"Index", type number}}),
    Partition = Table.Group(Source, {"Date"}, {{"Partition", each Table.AddIndexColumn(_, "Ranking",1,1), type table}}),
    #"Expanded Partition" = Table.ExpandTableColumn(Partition, "Partition", {"Index", "Ranking"}, {"Index", "Ranking"})
in
        #"Expanded Partition"
