    #"Changed Type" = Table.TransformColumnTypes(Source,{{"BLG", type text}, {"LORT", type text}, {"EUR", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"BLG"}, {{"Count", ( t ) => { t{0}[BLG] } & t[LORT] & t[EUR], type list  }}),
    Custom1 = List.Sort ( #"Grouped Rows"[Count], ( x ) => - List.Count ( x ) ),
    Custom2 = Table.FromList (
    Custom1,
    ( x ) => x,
    { "BLG"} & List.Transform ( { 1 .. List.Count ( Custom1{0} ) - 1 }, ( y ) => "Column" & Text.From ( y ) )
