寻找两组之间的唯一性
Finding unique between two groups
谁能告诉我如何根据以下 table 编写一个公式来识别所有拥有不同产品或产品基础发生变化的客户 ID？
结果：在 C 列上显示具有不同产品的客户 ID 1 和 3
我认为 COUNTIFS 可以有效地解决这个问题
=COUNTIFS($A:$A,"="&A2,$B:$B,"="&B2)
我在C列的公式是：
=COUNTIFS($A:$A;A2;$B:$B;B2)=COUNTIF$A:$A;A2)
无论客户是否一直购买相同的产品，此公式都将 return True/False。您对那些购买了 不同 产品的客户感兴趣，因此您希望在这种情况下按 FALSE 选项进行过滤：
如果你有 E365，你就有 UNIQUE 和 FILTER 等功能，所以你可以使用公式而不是手动过滤范围。
我认为 excel 函数不能为您提供 non-single 结果的串联答案。 VBA 可以解决这个问题。
假设您的数据将是：
- 数据范围 A2:B11（在 A1:B1 中排除了 headers），假定 non-blank 个单元格
- 按 CustomerID（按任何类型的订单）排序，VBA 脚本将 运行 沿着您排序的 CustomerID 列
- result(s)（CustomerIDs 有超过 1 个产品）将从 C2 沿着 C 列打印。因此，请确保清除 C 列中的现有数据。
VBA 脚本应该是：
Sub list()
Dim i As Integer
Dim cell As Range
Dim d_cust() As Variant
Set customerID = ActiveSheet.Range("$A:" & Range("A2").End(xlDown).Address)
Set Product = ActiveSheet.Range("$B:" & Range("B2").End(xlDown).Address)
i = 0
For Each cell In customerID
On Error Resume Next
If cell.Value <> d_cust(i - 1) And Evaluate("=SUMPRODUCT((" & customerID.Address & "=" & cell.Value & ")/(COUNTIFS(" & Product.Address & "," & Product.Address & "," & customerID.Address & "," & Chr(34) & cell.Value & Chr(34) & ")+(" & customerID.Address & "<>" & cell.Value & ")))") > 1 Then
ReDim Preserve d_cust(0 To i) As Variant
d_cust(i) = cell.Value
ActiveSheet.Cells((2 + i), 3) = cell.Value
i = i + 1
End If
Next cell
End Sub
这是C2中C列的结果，每个单元格1个结果。你可以改变
通过更改起始单元格和方向 此处 的结果 row/column：ActiveSheet.Cells((2 + i), 3) = cell.Value
如@Foxfire 和 Burns 和 Burns 所述，如果您有 O365，则可以使用 Filter 和 Unique。它看起来像这样：
=UNIQUE(FILTER(A2:A11,COUNTIFS(A2:A11,A2:A11,B2:B11,"<>"&B2:B11)<>0))
如果您没有 O365，您可以恢复为 pull-down 公式。如果你在 D2 中输入它，比如说，它将是：
=IFERROR(INDEX(A:A,MATCH(1,(COUNTIFS(A:A,A:A,B:B,"<>"&B:B)<>0)*(COUNTIF(D1:D,A:A)=0),0)),"")
作为数组公式输入。
