[英]VBA (RFC) SAP export to excel
我正在编写一个用于连接到 sap 系统的 VB 应用程序(使用 rfc)。 一切正常,我也获得了连接和数据。
尽管如此,保存访问数据并将其写入excel文件的代码确实很慢。
连接后我调用 RFC_READ_TABLE,它在 <5 秒内返回结果,这是完美的。 写入 excel(逐个单元格)非常慢。 有什么方法可以将整个 tblData '导出' 到 excel 并且不依赖于逐个单元地写入?
提前致谢!
If RFC_READ_TABLE.Call = True Then
MsgBox tblData.RowCount
If tblData.RowCount > 0 Then
' Write table header
For j = 1 To Size
Cells(1, j).Value = ColumnNames(j)
Next j
Size = UBound(ColumnNames, 1) - LBound(ColumnNames, 1) + 1
For i = 1 To tblData.RowCount
DoEvents
Textzeile = tblData(i, "WA")
For j = 1 To Size
Cells(i + 1, j).Value = LTrim(RTrim(getPieceOfTextzeile(Textzeile)))
Next j
Next
Else
MsgBox "No entries found in system " & SYSID, vbInformation
End If
Else
MsgBox "ERROR CALLING SAP REMOTE FUNCTION CALL"
End If
如果数据准备好(不需要处理),这样的事情可能是一个解决方案:
Sub Sap()
Const cStrStart As String = "A1" 'First cell of the resulting data
Dim tbldata
Dim arrSap As Variant 'Will become a one-based two dimensional array
Dim oRng As Range
arrSap = tbldata 'Data is in the array.
'Calculate the range: Must be the same size as arrSap
Set oRng = Range(Cells(Range(cStrStart).Row, UBound(arrSap)), _
Cells(Range(cStrStart)).Column, UBound(arrSap, 2))
oRng = arrSap 'Paste array into range.
End Sub
由于您需要从 tbldata 处理您的数据,因此您不需要对范围执行任何操作,而是处理应该更快的数组:
Sub Sap()
Const cStrStart As String = "A1" 'First cell of the resulting data
Dim arrSap() As Variant
Dim oRng As Range
Dim Size As Integer
If RFC_READ_TABLE.Call = True Then
'-------------------------------------------------------------------------------
MsgBox tbldata.RowCount
If tbldata.RowCount > 0 Then
Size = UBound(ColumnNames, 1) - LBound(ColumnNames, 1) + 1
ReDim arrSap(1 To tbldata.RowCount + 1, 1 To Size) '+ 1 for header
' Write table header
For j = 1 To Size
arrSap(1, j).Value = ColumnNames(j)
Next j
' Write data
For i = 1 + 1 To tbldata.RowCount + 1 '+ 1 for header
DoEvents
'- 1 due to header, don't know what "WA" is
Textzeile = tbldata(i - 1, "WA")
For j = 1 To Size
arrSap(i, j) = _
LTrim(RTrim(getPieceOfTextzeile(Textzeile)))
Next j
Next
'-------------------------------------------------------------------------------
'Calculate the range: Must be the same size as arrSap
Set oRng = Range(Cells(Range(cStrStart).Row, Range(cStrStart).Column), _
Cells(UBound(arrSap) + Range(cStrStart).Row -1, _
UBound(arrSap, 2) + Range(cStrStart).Column -1))
oRng = arrSap
'-------------------------------------------------------------------------------
Else
MsgBox "No entries found in system " & SYSID, vbInformation
End If
Else
MsgBox "ERROR CALLING SAP REMOTE FUNCTION CALL"
End If
End Sub
现在调整 cStrStart,检查其余的代码,你就可以开始了。
我还没有创建一个工作示例,所以我编辑了几次这段代码。 仔细检查以免丢失数据。
