Excel Power Query 高级编辑器将代码分解为多个步骤答案

【问题标题】：Excel Power Query Advanced Editor breaking code into stepsExcel Power Query 高级编辑器将代码分解为多个步骤

【问题描述】：

我在电源查询中创建了一个新查询并打开了高级编辑器来调整其中一个步骤。查询工作正常，但所有步骤都已从右侧的“已应用步骤”菜单中消失并合并为一个步骤。

我如何再次将这些分解成小步骤（这更容易理解和排除故障）？

每次使用高级编辑器时都会发生这种情况吗？

我的代码如下。我可以在右侧的“已应用步骤”菜单中以某种方式将每一行显示为单独的步骤吗？

let

    Source = Excel.CurrentWorkbook(){[Name="FlagsAllClients"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Portfolio Manager", type text}, {"Client ID", type text}, {"Client Name", type text}, {"KE", type text}, {"Portfolio ID", type text}, {"Days Out", Int64.Type}, {"Risk Category", type text}, {"Risk", type text}, {"Tracking Error", type text}, {"Concentration", type text}, {"Sector", type text}, {"Buy-List", type text}, {"Max Hld Wt", type text}, {"Anom. Hldgs", type text}, {"Concentration Issuer", type text}, {"Portfolio Value", type number}, {"Date", type datetime}}),

    #"Merged Queries" = Table.NestedJoin(#"Changed Type",{"Portfolio Manager"},BD_Office,{"BG"},"BD_Office",JoinKind.LeftOuter),
    #"Expanded BD_Office" = Table.ExpandTableColumn(#"Merged Queries", "BD_Office", {"Team"}, {"BD_Office.Team"}),
    #"Merged Queries1" = Table.NestedJoin(#"Expanded BD_Office",{"Client ID"},FlagsT,{"Client ID"},"FlagsT",JoinKind.LeftOuter),
    #"Expanded FlagsT" = Table.ExpandTableColumn(#"Merged Queries1", "FlagsT", {"Risk", "Sector", "Buy-List", "Max Hld Wt"}, {"FlagsT.Risk", "FlagsT.Sector", "FlagsT.Buy-List", "FlagsT.Max Hld Wt"}),
    #"Merged Queries2" = Table.NestedJoin(#"Expanded FlagsT",{"Client ID"},FlagsT_1,{"Client ID"},"FlagsT_1",JoinKind.LeftOuter),
    #"Expanded FlagsT_1" = Table.ExpandTableColumn(#"Merged Queries2", "FlagsT_1", {"Risk", "Sector", "Buy-List", "Max Hld Wt"}, {"FlagsT_1.Risk", "FlagsT_1.Sector", "FlagsT_1.Buy-List", "FlagsT_1.Max Hld Wt"}),
    #"Removed Other Columns" = Table.SelectColumns(#"Expanded FlagsT_1",{"Portfolio Manager", "Client ID", "Client Name", "KE", "Portfolio Value", "BD_Office.Team", "FlagsT.Risk", "FlagsT.Sector", "FlagsT.Buy-List", "FlagsT.Max Hld Wt", "FlagsT_1.Risk", "FlagsT_1.Sector", "FlagsT_1.Buy-List", "FlagsT_1.Max Hld Wt"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Removed Other Columns",{"BD_Office.Team", "Portfolio Manager", "Client ID", "Client Name", "KE", "Portfolio Value", "FlagsT.Risk", "FlagsT.Sector", "FlagsT.Buy-List", "FlagsT.Max Hld Wt", "FlagsT_1.Risk", "FlagsT_1.Sector", "FlagsT_1.Buy-List", "FlagsT_1.Max Hld Wt"}),
    #"Replaced Value" = Table.ReplaceValue(#"Reordered Columns","X","1",Replacer.ReplaceValue,{"FlagsT.Risk","FlagsT.Sector","FlagsT.Buy-List","FlagsT.Max Hld Wt","FlagsT_1.Risk","FlagsT_1.Sector","FlagsT_1.Buy-List","FlagsT_1.Max Hld Wt"}),
    #"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","!","0",Replacer.ReplaceText,{"FlagsT.Risk","FlagsT.Sector","FlagsT.Buy-List","FlagsT.Max Hld Wt","FlagsT_1.Risk","FlagsT_1.Sector","FlagsT_1.Buy-List","FlagsT_1.Max Hld Wt"}),
    #"Replaced Value2" = Table.ReplaceValue(#"Replaced Value","2","0",Replacer.ReplaceText,{"FlagsT.Risk","FlagsT.Sector","FlagsT.Buy-List","FlagsT.Max Hld Wt","FlagsT_1.Risk","FlagsT_1.Sector","FlagsT_1.Buy-List","FlagsT_1.Max Hld Wt"})

in

    #"Replaced Value1"

【问题讨论】：

你忘了在最后一行Table.ReplaceValue改表名，最后一行应该是#"Replaced Value2"

【解决方案1】：

我认为这里的问题是您在最后一行中的 in 引用指的是 M 代码中倒数第二个步骤。如果您将in #"Replaced Value1" 更改为in #"Replaced Value2"，我怀疑它的行为会更像您的预期。

您可能还希望#"Replaced Value2" 行引用#"Replaced Value1"，而不是第二次引用#"Replaced Value"。

基本上，我没有在电源编辑器中引用上一步。帮助我理解我做错了什么的解释发布在https://social.technet.microsoft.com/Forums/en-US/bfe0e2e4-16e0-4d76-b3b9-27a43ce27866/excel-power-query-advanced-editor-breaking-code-into-steps?forum=powerquery

电源查询代码通常是这样写的：

        let
            step1 = blah blah,
            step2 = blah(step1 blah),
            step3 = blah(step2, blah)
        in
            step3

所以如果你添加一个新步骤，请记住接下来的步骤必须引用它，并且“in”之后最后一行的步骤应该是最后一步。你可能忘了改变 “in”后的步骤名称
