Power Query - 基于两个条件的组/ Unpivot 列表

Question

我有一个包含此类信息的巨大列表：

现在我想对这个列表进行分组/逆透视以获取每个订单号

基于键 1 = 70 和键 2 = 10 和
基于键 1 = 70 和键 2 = 20 的最大销售价值

结果会是这样：

如何使用 Power Query 做到这一点？

Answer 1

你可以这样做：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQwUNJRMgURhhCWgVKsDkzcDEQYgQgTFHFzuHoLHOLmphjiRhATYeKGOOw1xGGvIQ57DXHYa4hiL1h9LAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Order Number" = _t, #"Key 1" = _t, #"Key 2" = _t, #"Sales Value" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Order Number", Int64.Type}, {"Key 1", Int64.Type}, {"Key 2", Int64.Type}, {"Sales Value", Int64.Type}}),
    #"Merged Columns" = Table.CombineColumns(Table.TransformColumnTypes(#"Changed Type", {{"Key 1", type text}, {"Key 2", type text}}, "de-CH"),{"Key 1", "Key 2"},Combiner.CombineTextByDelimiter("", QuoteStyle.None),"Merged"),
    #"Filtered Rows" = Table.SelectRows(#"Merged Columns", each ([Merged] = "7010" or [Merged] = "7020")),
    #"Pivoted Column" = Table.Pivot(#"Filtered Rows", List.Distinct(#"Filtered Rows"[Merged]), "Merged", "Sales Value", List.Max)
in
    #"Pivoted Column"

输出：

Power Query - 基于两个条件的组/ Unpivot 列表
