    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Code article", type text}, {"Division", type text}, {"Date", type date}, {"Consommation", Int64.Type}, {"Couverture 1%", Int64.Type}, {"Livraison Prevue", Int64.Type}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Date", "Division", "Code article"}, "Attribute", "Value"),
    #"Pivoted Column" = Table.Pivot(Table.TransformColumnTypes(#"Unpivoted Other Columns", {{"Date", type text}}, "en-US"), List.Distinct(Table.TransformColumnTypes(#"Unpivoted Other Columns", {{"Date", type text}}, "en-US")[Date]), "Date", "Value", List.Sum)
