Excel VBA代码过滤两列并提取数据

Question

这是我的第一篇文章，我对此感到非常兴奋。如果我对编码/编程术语不太熟悉，如果我的写作没有意义，我提前道歉。

这是我正在使用的Micro_Enabled_Excel_File。

我有一个包含多列和多行的 excel 文件。随着时间的推移，行数会增加。我正在尝试过滤两列并复制最新/最近的数据点（行）并将其粘贴到新工作表中以创建状态报告。

结果会是什么样子：image

到目前为止我做了什么：

1. 创建了一个 Micro 来遍历“SCOPE”和“TRADE NAME”列以获取唯一条目并将其复制到另一个名为“Code”的工作表中。

Sub First_COPY_STYLE_TO_REPORT()

    'creating the Report sheet
    Sheets("Report").Select
    Cells.Select
    Selection.Delete Shift:=xlUp
    Sheets("Status Updates").Select
    Cells.Select
    Selection.Copy
    Sheets("Report").Select
    ActiveSheet.Paste
    Rows("2:1048576").Select
    Application.CutCopyMode = False
    Selection.ClearContents

End Sub

1. 创建了一个 Micro 来为工作表“报告”创建一个模板，该模板最终将填充下一个 Micro 的结果。

Sub Second_COPY_UNIQUE_TO_CODE()

'add title to filter columns in the Code sheet
    Sheets("Code").Select
    Rows("1:1").Select
    Selection.Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove
    Range("A1").Select
    ActiveCell.FormulaR1C1 = "Filter1"
    Range("B1").Select
    ActiveCell.FormulaR1C1 = "Filter2"

'creating the filter criteria also known as scope and trade name

    'Finds Duplicates on SCOPE column and copies it to a new sheet called CODE
    Sheets("Status Updates").Select
    Dim s1 As Worksheet, s2 As Worksheet
    Set s1 = Sheets("Status Updates")
    Set s2 = Sheets("Code")
    s1.Range(Range("B2"), Range("B2").End(xlDown)).Copy s2.Range("A2")
    s2.Range("A:A").RemoveDuplicates Columns:=1, Header:=xlNo

    'Finds Duplicates on NAME column and copies it to a new sheet called CODE
    Dim s3 As Worksheet, s4 As Worksheet
    Set s3 = Sheets("Status Updates")
    Set s4 = Sheets("Code")
    s1.Range(Range("C2"), Range("C2").End(xlDown)).Copy s2.Range("B2")
    s4.Range("B:B").RemoveDuplicates Columns:=1, Header:=xlNo

    'Clears formating and autofits column widths
    Sheets("Code").Cells.ClearFormats
    ThisWorkbook.Worksheets("Code").Cells.EntireColumn.AutoFit

End Sub

1. 创建了一个 Micro（不起作用），其中包括两个循环来过滤两列，对第一列进行排序，并将工作表的第二行复制并粘贴到工作表“报告”中。

Sub Third_Generate_Latest_Status_Report()

    Dim a1 As Long, a2 As Long, b1 As Long, b2 As Long
        a1 = Cells.Find("Filter1").Offset(1, 0).Row
        a2 = Cells.Find("Filter1").End(xlDown).Row
        b1 = Cells.Find("Filter2").Offset(1, 0).Row
        b2 = Cells.Find("Filter2").End(xlDown).Row

    Dim g As Long, i As Long

    For g = a1 To a2 'Look up for Filter1 column. Then loop through all criterias.
        ActiveSheet.Range("$C$1:$J$300").AutoFilter Field:=2, Criteria1:=g
        For i = b1 To b2 'Look up for Filter2 column. Then loop through all criterias.
            ActiveSheet.Range("$C$1:$J$300").AutoFilter Field:=3, Criteria1:=i

            'sort the NO column from largest to smallest (to get the latest/most recent update).
            'I have copied this part of the code from the Micro I recorded.
            ActiveWorkbook.Worksheets("Status Updates").AutoFilter.Sort.SortFields.Clear
            ActiveWorkbook.Worksheets("Status Updates").AutoFilter.Sort.SortFields.Add2 _
                Key:=Range("C1:C300"), SortOn:=xlSortOnValues, Order:=xlDescending, _
                DataOption:=xlSortNormal
            With ActiveWorkbook.Worksheets("Status Updates").AutoFilter.Sort
                .Header = xlYes
                .MatchCase = False
                .Orientation = xlTopToBottom
                .SortMethod = xlPinYin
                .Apply
                'I think I need to add code here to copy the row to sheet Report, and run the loop again
            End With
        Next i 'take next value in column Filter2
    Next g 'take next value in column Filter1
End Sub

我认为我需要什么：

1. 工作表“状态更新” - 过滤“范围”列并遍历所有条件。然后，
2. 工作表“状态更新” - 过滤“贸易名称”列并遍历所有条件。
3. 对“NO”列进行排序以获得最新的数据点。
4. 复制第一行数据（即标题后的第一行）
5. 将其粘贴到另一个名为“报告”的工作表中。

能否请您看一下我的代码并告诉我我的错误是什么？

这是我第一次编码/编程/使用 VBA。

Answer 1

拥有额外的“代码”表通常只会使事情变得不必要地复杂。并且因为您的“状态更新”表已经按照从最旧的更新到最新的更新进行了排序，我们知道对于任何给定的独特组合，您总是想要底部的更新。如果我们向后循环您的数据（从底行到第一行，这就是 Step -1 所做的），我们可以保证拉动它。

然后使用字典检查唯一组合并提取每个唯一组合的第一个遇到的行（请记住，我们要倒退，所以第一个遇到的行将是最新的更新）并将这些行复制到您的报告表.

最后，这是一个相当适合初学者的代码版本。为了清楚起见，我对它进行了大量评论，以便您可以跟随并理解它的作用。

                Set rCopy = rUpdateData.Cells(i, 1)

                Set rCopy = Union(rCopy, rUpdateData.Cells(i, 1))
