Copy rows from one workbook to another with criteria

Hi,

I am trying to adapt some code from an Expert to another problem.

I have two workbooks, Both have dates in column A. I want to open the source pull all rows from the source workbook who's date in column A is greater than the latest date in Column A of the destination workbook (could be any name). The macro runs in the destination workbook. The following runs without errors but doesn't pull any rows over.

Option Explicit


Sub LoadData()
    Dim LastRow As Long
    Dim MainFile As String
    Dim SrcFile As String
    Dim WS1 As Worksheet
    Dim WS2 As Worksheet
    Dim cCell As Range
    Dim MaxDate As Date
    Dim I As Long, MaxRow1 As Long, MaxRow2 As Long
   
   ' Application.ScreenUpdating = False
    MainFile = ActiveWorkbook.Name 'name of the workbook with the macro which is the destination workbook
    Workbooks.Open "c:\!data/testdata.xls" '<do I need to activate this workbook before proceeding?
    SrcFile = ActiveWorkbook.Name 'name of the source workbook
    Workbooks(SrcFile).Worksheets("Sheet1").Select
   
Dim rng1 As Range ' fixes dates on source workbook
Dim X
Set rng1 = Range([A1], Cells(Rows.Count, "A").End(xlUp))
X = rng1
rng1 = X

   
Set WS1 = Workbooks(SrcFile).Sheets("Sheet1")
MaxRow1 = WS1.Range("A" & WS1.Rows.Count).End(xlUp).Row
MaxDate = Application.WorksheetFunction.Max(WS1.Range("A:A"))

Set WS2 = Workbooks(MainFile).Sheets("Raw Data")
MaxRow2 = WS2.Range("A" & WS2.Rows.Count).End(xlUp).Row

For I = 2 To MaxRow2
    If WS2.Cells(I, "A") > MaxDate Then
        WS2.Cells(I, "A").EntireRow.Copy WS1.Cells(MaxRow1, "A")
        MaxRow1 = MaxRow1 + 1
    End If
Next I
   
   
    Application.DisplayAlerts = False  'avoids clipboard message
    Workbooks(SrcFile).Close SaveChanges:=False
    Application.DisplayAlerts = True

    Workbooks(MainFile).Worksheets("Table").Select
     
    Application.ScreenUpdating = True
    MsgBox "Data was successfully imported!", vbInformation
End Sub

Hoping someone can see what I'm doing wrong without having to post example workbooks but I could if necessary.

Thanks in advance,

Try this

Sub LoadData()
    Dim srcWb As Workbook
    Dim srcWs As Worksheet, destWs As Worksheet
    Dim maxDate As Date
    Dim i As Long, destCurrRow
    
   ' Application.ScreenUpdating = False
    DestWb = ActiveWorkbook 'name of the workbook with the macro which is the destination workbook
    Set destWs = ActiveWorkbook.Sheets("Raw Data")
    Set srcWb = Workbooks.Open("c:\!data/testdata.xls")
    Set srcWs = srcWb.Sheets("Sheet1")
    
    'Get Max Date
    maxDate = Application.WorksheetFunction.Max(destWs.Range("A:A"))
    
    destCurrRow = destWs.Range("A" & Rows.Count).End(xlUp).Row + 1

    For i = 2 To srcWs.Range("A" & Row.Count).End(xlUp).Row
        If srcWs.Range("A" & i).Value > maxDate Then
            srcWs.Range("A" & i).EntireRow.Copy destWs.Range("A" & destCurrRow)
            destCurrRow = destCurrRow + 1
        End If
    Next i
    
    Application.DisplayAlerts = False  'avoids clipboard message
    srcWb.Close SaveChanges:=False
    Application.DisplayAlerts = True

    Workbooks(MainFile).Worksheets("Table").Select
      
    Application.ScreenUpdating = True
    MsgBox "Data was successfully imported!", vbInformation
End Sub

Open in new window


Just a note but always try to use meaningful variable names as it makes your code far easier to read

Hi Michael74,

Thanks for the reply. I'm getting Run Time error 438 "Object doesn't support this property or method on the first line of code after the Dim statements:

DestWb = ActiveWorkbook 'name of the workbook with the macro which is the destination workbook

Any ideas? Should I use "ThisWorkbook"?

Thanks,

Sorry this line should be

Set DestWb = ActiveWorkbook

Open in new window


ThisWorkBook would also achieve the same thing, I just left out the Set keyword.

After having a second look this line is not required anyway and it is just there because I forgot to clean it up. Here is amended code

Sub LoadData()
    Dim srcWb As Workbook
    Dim srcWs As Worksheet, destWs As Worksheet
    Dim maxDate As Date
    Dim i As Long, destCurrRow As Long
    
    Application.ScreenUpdating = False
    Set destWs = ActiveWorkbook.Sheets("Raw Data")
    Set srcWb = Workbooks.Open("c:\!data/testdata.xls")
    Set srcWs = srcWb.Sheets("Sheet1")
    
    'Get Max Date
    maxDate = Application.WorksheetFunction.Max(destWs.Range("A:A"))
    
    destCurrRow = destWs.Range("A" & Rows.Count).End(xlUp).Row + 1

    For i = 2 To srcWs.Range("A" & Row.Count).End(xlUp).Row
        If srcWs.Range("A" & i).Value > maxDate Then
            srcWs.Range("A" & i).EntireRow.Copy destWs.Range("A" & destCurrRow)
            destCurrRow = destCurrRow + 1
        End If
    Next i
    
    Application.DisplayAlerts = False  'avoids clipboard message
    srcWb.Close SaveChanges:=False
    Application.DisplayAlerts = True

    Worksheets("Table").Select
      
    Application.ScreenUpdating = True
    MsgBox "Data was successfully imported!", vbInformation
End Sub

Open in new window

Hi Michael74,

Thanks. Now I get runtime error 424 "Object required" on this line:

For i = 2 To srcWs.Range("A" & Row.Count).End(xlUp).Row

Thanks,

Hi MIchaei74,

Thank you, it works. I really appreciate the help.

This has, however, created another issue I did not foresee... the code is taking more than 17 minutes to run as the source worksheet has more than 50,000 rows and it's copying over 10,000 to 15,000 that are dated later than the latest date in the destination workbook. Any ideas and/or would you mind if I created another question to ask about improving the run speed of this solution?

Thanks again,
