【问题描述】：

我有销售表

我想为每个 SalesName 找到 Product，并在 Month 之前找到最大 Revenue。

如果此值 (Revenue) 大于 SalesName 的 TotalRevenue 的 70%（按月计算）（在月），然后我需要产品名称。

否则我需要找到当月 2 大收入的产品名称。

[请看附图]

【问题讨论】：

您的示例数据没有客户字段，因此不确定如何按月获取客户
对不起，我已经编辑了这个问题。必须有销售名称。

下面的示例解决方案最难的部分是获得顶级产品。您可以通过分组和添加索引，然后进行过滤来做到这一点。剩下的只是将所有表格合并在一起并添加一个自定义列来决定显示哪个答案

let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"SalesName", type text}, {"Product", type text}, {"Month", type text}, {"Revenue", Int64.Type}}),

// find top 2 Product for Salesname/Month
#"Grouped Rows" = Table.Group(#"Changed Type", {"SalesName","Month"}, {{"All", each Table.AddIndexColumn(Table.Sort(_,{{"Revenue", Order.Descending}}),"Index",1,1), type table}}),
#"Expanded All" = Table.ExpandTableColumn(#"Grouped Rows", "All", {"Product", "Revenue", "Index"}, {"Product", "Revenue", "Index"}),
#"Filtered Rows" = Table.SelectRows(#"Expanded All", each ([Index] =1 or [Index]=2)),
// Combine the two Products into one row separated by a ;
Top2= Table.Group( #"Filtered Rows", {"SalesName", "Month"}, {{"Top2", each Text.Combine([Product], "; "), type text}}),

//70% of Revenue for Salesname/Month
Percent70 = Table.Group(#"Changed Type", {"SalesName", "Month"}, {{"70%Revenue", each .7*List.Sum([Revenue]), type number}}),

//Top product each month for SaleName
#"Filtered Rows2" = Table.SelectRows(#"Expanded All", each [Index] =1),

// Merge in Top2
#"Merged Queries" = Table.NestedJoin(#"Filtered Rows2",{"SalesName", "Month"},Top2,{"SalesName", "Month"},"Top2",JoinKind.LeftOuter),
#"Expanded Top2" = Table.ExpandTableColumn(#"Merged Queries", "Top2", {"Top2"}, {"Top2"}),

// Merge in 70% Revenue
#"Merged Queries2" = Table.NestedJoin(#"Expanded Top2",{"SalesName", "Month"},Percent70,{"SalesName", "Month"},"70Percent",JoinKind.LeftOuter),
#"Expanded 70Percent" = Table.ExpandTableColumn(#"Merged Queries2", "70Percent", {"70%Revenue"}, {"70%Revenue"}),

// Compare revenue to 70% revenue and pick either Product or top 2 Products
#"Added Custom" = Table.AddColumn(#"Expanded 70Percent", "Custom", each if [Revenue]>[#"70%Revenue"] then [Product] else [Top2]),
#"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Index", "Top2", "70%Revenue"})

in #"Removed Columns"
