  • Hi RENJITH_R_S 

    Download sample PBIX file with this code.

    This works in Power Query

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclSK1YlWcgKTzmASWcQRRsYCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t]),
        #"Added Index" = Table.AddIndexColumn(Source, "Index", 1, 1, Int64.Type),
        #"Added Custom" = Table.AddColumn(#"Added Index", "Custom", each if [Name] = "A" then List.Count(List.Select(List.FirstN(#"Added Index"[Name], [Index]), each _ = "A")) else ""),
        #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Index"})
    in
        #"Removed Columns"

     

    I'll see if I can do it in DAX too.

    Regards

    Phil

      Hello

      And what would it be like if I wanted him to tell me all the lyrics? For example, when sorting the names, it would look like this:

      A 1

      A 2

      A 3

      A 4

      B 1

      B 2

      C 1

      In advance thank you very much!
