Hi , kartiklal70 

According to your description, you want to pivot the table.

This is my test data:

Do you mean you want to get this table:

If this , you can put this M code in "Advanced Editor":

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("jZBNDoIwEEavQromGRmgyJJwASNLwgKxMU2gRX48v5W0OIlC2H3TeZ15bVmyCIIY8IQB81mAtkBTFFcvH0Q9iTur/JKZ89BxESC6nDXPWY6T1MrLddcJ1dgLKWDqZtFc6HZe8KzvB/2ytGmYkdEHCk2+tLVSUj28Yr51chzt+L4Vk1h4qs0BN6QpRfOmNCevTIC7+N/5DCtL4hF1Tn98XfLjnrpWDMkRdfyq4746hWnel6/e", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Actual Date" = _t, #"Forecast Date" = _t, Name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Actual Date", type date}, {"Forecast Date", type date}, {"Name", type text}}),
    Custom1 = Table.Group(#"Changed Type","Name",{{"Actual",(x)=>x[Actual Date] },{"Forecast",(y)=>y[Forecast Date]}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(Custom1, {"Name"}, "Attribute", "Value"),
    #"Merged Columns" = Table.CombineColumns(#"Unpivoted Columns",{"Name", "Attribute"},Combiner.CombineTextByDelimiter(" ", QuoteStyle.None),"Merged"),
    Custom2 = Table.TransformColumns( #"Merged Columns",{"Value",(x)=> Table.AddIndexColumn( Table.Sort(Table.FromColumns({x}),"Column1"), "Index", 1)             }),
    #"Expanded Value" = Table.ExpandTableColumn(Custom2, "Value", {"Column1", "Index"}, {"Column1", "Index"}),
    #"Pivoted Column" = Table.Pivot(#"Expanded Value", List.Distinct(#"Expanded Value"[Merged]), "Merged", "Column1")
in
    #"Pivoted Column"

Then we can get the table you want to .

 

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
