SAP GUI ID is changing

I want to do a mass upload of data in SAP, say update the price on 100 PO's. I can write a macro using VB Script and run it through the SAP script recording and playback option, but while doing it the macro gets stuck as the SAP GUI Id gets changed time to time. Is there a fix fo开发者_开发百科r this?

Example code:

If Not IsObject(application) Then
   Set SapGuiAuto  = GetObject("SAPGUI")
   Set application = 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

do you use any specific transaction? by the way delete the part until maximize at first. And put this

Set SapGuiAuto = GetObject("SAPGUI")   
 Set SAPApp = SapGuiAuto.GetScriptingEngine 
    Set SAPCon = SAPApp.Children(0) 
    Set session = SAPCon.Children(0)
