Help sort 12 rolling months in order

Good day mespiritu ,

As it stands "Rolling months" does not give a unique sort order for "Attribute" as it provides no distinction between the same month name in different years. To provide such a distinction you could

1. Add a custom column (which I call "Sort Date") which converts "Attribute" to the first of the month.
2. In Table View sort "Attribute" by "Sort Date".

Here is sample code...

let
  Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8irNMTJW0lEyUYrViVZyLE0H88zAPJCcCZBnDJcD8YyUYmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Attribute = _t, Value = _t]),
  #"Changed Type" = Table.TransformColumnTypes(Source,{{"Value", Int64.Type}}),
  #"Added Sort Date" = Table.AddColumn(#"Changed Type", "Sort Date", each Date.FromText([Attribute],[Format="MMMyy"]), type date)
in
  #"Added Sort Date"

 This yields,

Hope this helps
