excel - 创建循环以从 SAP 下载附件文档

问题描述

我每天都会获得文档列表（接近 500 个唯一文档编号），我需要从 SAP 下载每个文档的附件。我记录了 SAP 脚本，但我无法遍历所有 5 个文档。需要帮忙。

我需要输入文件编号、公司代码和会计年度。（所有将是动态的“）我如何创建一个变量和循环来从我的 Excel 表中为这三个标准选择值？

Public Sub SAPlogin()


    Set WshShell = CreateObject("WScript.Shell")
Set proc = WshShell.Exec("C:\Program Files (x86)\SAP\FrontEnd\SAPgui\saplogon.exe")

            Dim temp
    temp = Timer
    Do While Timer - temp < 5
    Loop
Set SapGui = GetObject("SAPGUI")
Set Appl = SapGui.GetScriptingEngine

Set Connection = Appl.Openconnection("ERP", True)
Set session = Connection.Children(0)

session.findById("wnd[0]/usr/txtRSYST-BNAME").Text = "XXXX"
session.findById("wnd[0]/usr/pwdRSYST-BCODE").Text = "XXXX"
session.findById("wnd[0]/usr/txtRSYST-LANGU").Text = "EN"
session.findById("wnd[0]").sendVKey 0

If Not IsObject(Application) Then
   Set SapGuiAuto = GetObject("SAPGUI")
   Set Appl = SapGuiAuto.GetScriptingEngine
End If
If Not IsObject(Connection) Then
   Set Connection = Application.Children(0)
End If
If Not IsObject(session) Then
   Set session = Connection.Children(0)
End If
If IsObject(WScript) Then
   WScript.ConnectObject session, "on"
   WScript.ConnectObject Application, "on"
End If
session.findById("wnd[0]").maximize
session.findById("wnd[0]/tbar[0]/okcd").Text = "fb03"
session.findById("wnd[0]").sendVKey 0
session.findById("wnd[0]/usr/txtRF05L-BELNR").Text = "1"
session.findById("wnd[0]/usr/ctxtRF05L-BUKRS").Text = "20"
session.findById("wnd[0]/usr/txtRF05L-GJAHR").Text = "2019"
session.findById("wnd[0]/usr/txtRF05L-GJAHR").SetFocus
session.findById("wnd[0]/usr/txtRF05L-GJAHR").caretPosition = 4
session.findById("wnd[0]").sendVKey 0
session.findById("wnd[0]/titl/shellcont/shell").pressContextButton "%GOS_TOOLBOX"
session.findById("wnd[0]/titl/shellcont/shell").selectContextMenuItem "%GOS_VIEW_ATTA"
session.findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").currentCellColumn = "BITM_DESCR"
session.findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").selectedRows = "0"
session.findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").pressToolbarButton "%ATTA_EXPORT"
session.findById("wnd[1]/tbar[0]/btn[0]").press
session.findById("wnd[0]").sendVKey 12
session.findById("wnd[0]/usr/txtRF05L-BELNR").Text = "2"
session.findById("wnd[0]").sendVKey 0
session.findById("wnd[0]/titl/shellcont/shell").pressContextButton "%GOS_TOOLBOX"
session.findById("wnd[0]/titl/shellcont/shell").selectContextMenuItem "%GOS_VIEW_ATTA"
session.findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").currentCellColumn = "BITM_DESCR"
session.findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").selectedRows = "0"
session.findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").pressToolbarButton "%ATTA_EXPORT"
session.findById("wnd[1]/tbar[0]/btn[0]").press
session.findById("wnd[0]").sendVKey 12



End Sub

解决方案

首先简化您拥有的脚本，将其分解为更小的组件。例如，创建一个用于登录的函数，特别是如果您要开始创建几个不同的函数。

Public Function StartSAPSession() as Variant
    ' Enter your script here for logging in and starting a new session
    '....

    ' Return the session
    Set StartSAPSession = Connection.Children(0)
End Function

我会全局声明会话对象，这样每次运行宏时都不需要登录并打开新会话。请注意，使用小写的会话将简化从 SAP GUI 脚本记录器复制和粘贴的过程。

Public session as Variant

然后实际上“做”你所追求的......

假设您有 Table1 和需要查询的 3 个字段；文件编号、公司代码和会计年度。我们将循环浏览此表中的每一行。我们还将假设每个文档的数量可能会发生变化。我们检查是否存在会话（如果不存在），填充查询字段，通过上下文菜单查看附件并下载它们。注意：我目前无权访问 SAP 实例，因此没有机会对此进行测试。它改编自我之前编译的工具。它需要逐步完成并进行一些测试。我通常还进行大量测试以了解可能收到的错误，然后找到有效处理它们的方法。无论如何，给你...

Public Function ExtractDocuments()
    Dim Arr() as Variant
    Dim DocNum as String
    Dim Company as String
    Dim FY as String
    Dim AttCnt as Integer
    Dim i as Long
    Dim j as Long

    ' When session is Nothing then we need to create a new session
    ' else assume we can re-use the session 
    If session Is Nothing Then
        Set session = StartSAPSession
    End If

    ' Load the table as an Array, this will be faster
    Arr = Range("Table1").ListObject.DataBodyRange

    ' Cycle through each row of the table (Arr)
    For i = 1 to Ubound(Arr, 1)
        ' Start by loading the row you will enter
        DocNum = Arr(i, 1)
        Company = Arr(i, 2)
        FY = Arr(i, 3)

        With session
            .findById("wnd[0]").maximize
            .StartTransaction "FB03"   ' Load the transaction you are after
            .findById("wnd[0]/usr/txtRF05L-BELNR").Text = DocNum
            .findById("wnd[0]/usr/ctxtRF05L-BUKRS").Text = Company
            .findById("wnd[0]/usr/txtRF05L-GJAHR").Text = FY
            .findById("wnd[0]").sendVKey 0    ' Execute transaction

            ' The query runs and you select context menu and attachments
            .findById("wnd[0]/titl/shellcont/shell").pressContextButton "%GOS_TOOLBOX"
            .findById("wnd[0]/titl/shellcont/shell").selectContextMenuItem "%GOS_VIEW_ATTA"

            ' How many attachments are there? If 1 or more then save each.
            AttCnt = .findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").RowCount
            If AttCnt > 0 Then
                For j = 0 to AttCnt -1
                    .findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").selectedRows = j
                    .findById("wnd[1]/usr/cntlCONTAINER_0100/shellcont/shell").pressToolbarButton "%ATTA_EXPORT"
                Next j
                .findById("wnd[1]/tbar[0]/btn[0]").press   ' Exit the Attachments window
            End If
        End With
    Next i
End Function

还有更多的机会将其进一步分解为更多的 Subs 和 Functions，以使其更具可读性和可重用性。

祝你好运！
