    Hi Anonymous ,

     

    We need to add an index column using Power Query Editor and create a calculate column to meet your requirement.

     

    1. Create an index column.

     

     

    2. Then we can create a calculate column.

     

    Rank column = 
RANKX(FILTER('Table','Table'[Name]=EARLIER('Table'[Name])),'Table'[Index],,ASC,Dense)

     

     

    If it doesn’t meet your requirement, could you please show the exact expected result based on the table that you have shared?

     

    Best regards,

Hi Anonymous ,

 

I think you would be better off indexing your rows using Power Query, using the index by group pattern, you will find a couple great links here,

http://datacornering.com/how-to-create-group-index-with-power-query-or-r/ 

https://radacad.com/create-row-number-for-each-group-in-power-bi-using-power-query 

 

Below please find the Power Query I used to create the index column that i think you are looking for

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WykrMTVXSUTJUitUBcvLzEGyIhBEyxxhJFYqECZIEUFEsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Name           " = _t, result = _t]),
    #"Removed Columns" = Table.RemoveColumns(Source,{"result"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Removed Columns",{{"Name           ", type text}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"Name           ", "Name"}}),
    #"Added Index" = Table.AddIndexColumn(#"Renamed Columns", "Index", 1, 1, Int64.Type),
    #"Grouped Rows" = Table.Group(#"Added Index", {"Name"}, {{"Count", each _, type table [Name=nullable text, Index=number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Ranker", each Table.AddIndexColumn([Count], "Rank", 1, 1)),
    #"Expanded Ranker" = Table.ExpandTableColumn(#"Added Custom", "Ranker", {"Rank"}, {"Ranker.Rank"})
in
    #"Expanded Ranker"

 

Hope this helps,

Richard
