Unpivot table w

Hi amolkulkarnigk1 ,

Based on the description, I'm assuming your table looks like this:

You can get the value of Wrong Rate by adding a custom column(After the twice Promoted Headers):

Advanced editor.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtAzMlLSUYKiWJ1opeAiPQW/fCDPLzE3FUg5FhTkQEUC8nMykyuDEktSwSoNQbJJyUDS0MjYBEQZgMVBBlZVQMSNwOKGSrGxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Promoted Headers1" = Table.PromoteHeaders(#"Promoted Headers", [PromoteAllScalars=true]),
    #"Added Custom" = Table.AddColumn(#"Promoted Headers1", "Wrong Rate", each Source[Column1]{0})
in
    #"Added Custom"
