Hello,

 

You need more than Unpivoting for your use case. Try the M-Script below.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("vZJBa8MwDIX/ishpg8az5diJeytjG2XdUprcQg9u6tJCSIcdyn7+5JYx2NnU8FmCKLzk6XVdtnF2gNrvnQ/ZLBMEEpIoCEVooiQqwsQZHq84KTDbzrpMSTSCA6z9AZpLH2DjLvQ015wO4/xfn6JEWW04Gg2wsrs5vHxPzo92iN/JEP9KOjXkqADqi/NHZ/dz+DiFHh4Gu3uMVrDy6hmTVUJRpQU3XAC8t8t83daQw+tp5zy8rRZNE30VWpYlK8prL6QUDIuUf82V4gbg+TxO3vZTyOvpSPpxzdFjKZmK2oXRyETS7RYKOYWqWdJuv9wYHLTejuFwCyr+pkncLVc0oK+lMvfLlZRcMRPfkAbNzexU0kaJAtGQye2yyRdPnzlAsIMLh7Pv3c3kSrAqBhsrzSUzMpX89gc=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t, Column5 = _t, Column6 = _t, Column7 = _t, Column8 = _t, Column9 = _t, Column10 = _t, Column11 = _t, Column12 = _t, Column13 = _t]),
    #"Transposed Table" = Table.Transpose(Source),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Transposed Table", {"Column1"}, "Attribute", "Value"),
    #"Changed Type" = Table.TransformColumnTypes(#"Unpivoted Other Columns",{{"Value", type text}}),
    RealOrdersName = Table.SelectRows(#"Changed Type", each ([Column1] = "Real Orders")),
    Custom1 = #"Unpivoted Other Columns",
    #"Filtered Rows1" = Table.SelectRows(Custom1, each [Column1] <> "Real Orders"),
    #"Merged Queries" = Table.NestedJoin(#"Filtered Rows1", {"Attribute"}, RealOrdersName, {"Attribute"}, "ColumnName", JoinKind.LeftOuter),
    #"Expanded ColumnName" = Table.ExpandTableColumn(#"Merged Queries", "ColumnName", {"Value"}, {"Real Orders"}),
    #"Renamed Columns" = Table.RenameColumns(#"Expanded ColumnName",{{"Column1", "Period"}, {"Value", "Amount"}}),
    #"Removed Other Columns" = Table.SelectColumns(#"Renamed Columns",{"Real Orders", "Amount", "Period"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Other Columns",{{"Amount", type number}, {"Period", Int64.Type}}),
    #"Sorted Rows" = Table.Sort(#"Changed Type1",{{"Period", Order.Ascending}})
in
    #"Sorted Rows"

Here's a screenshot of the result:

    Thank you for working on this and sorry for the delayed reply. Would it be possible to have the desired result data in the same sort order (Real Order column) as the original data?

        Hi, 

         

        I am just waiting to have the desired result data in the same sort order (Real Order column) as the original data. At the moment, I have not been able to resolve the issue.
