Create table from another table

Hi akarca ,

I have created a simple sample, please refer to my pbix fiel to see if it helps you.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bY8xDsIwDEXvkgkkS7GdxElGoAdgYqk6IEAMgCqh9v4kLW1DxeDBfnrfdl2r47u99pdOgTq1z/512zzu29RU5+6mGqjVLjUxFSOzJi3zkDASRO8mxtoNbJ+ZxcIZ54fREQski8MDq9LAoGEQu9aGOCaD4ORvJLvogXh9Yo60IoVlyuNNYJh32S/JeRy4IKFwxPhlC2rGeQ8HDBOJE8iKCdGAX+6mCY5fRQS2BSw+FmIIv6j5AA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"(blank)" = _t, #"(blank).1" = _t, #"(blank).2" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"(blank)", type text}, {"(blank).1", type text}, {"(blank).2", type text}}),
    #"Promoted Headers" = Table.PromoteHeaders(#"Changed Type", [PromoteAllScalars=true]),
    #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"Product", type text}, {"Volume(kg)", Int64.Type}, {"Date", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type1", "Custom", each Date.MonthName([Date])),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Date"}),
    #"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Custom]), "Custom", "Volume(kg)", List.Sum)
in
    #"Pivoted Column"
