VBA automation to read from SAP

Question

Hi,
Does anyone know how to read from an SAP screen using VBA code? I am NOT referring to reading from a table like VBAK, MARA etc.
The requirement is to enter a transaction code lets say VA03/VA43, enter a document/order number and read the contents of the screen using the screen field name like VBELN, KUNNR etc.
Regards

Using vbs:
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
session.findById("wnd[0]").maximize
session.findById("wnd[0]/tbar[0]/okcd").text = "VA03"
session.findById("wnd[0]/tbar[0]/btn[0]").press
session.findById("wnd[0]/usr/ctxtSOMEFIELDNAME").text = some_variable_you_can_store_later
etc, etc
I am not familiar with tath screen so you might need more code in wnd[0]/usr/ctxtSOMEFIELDNAME if there are multiple tabs.
It will be a lot easier to make SAP record the script: ALT+F12 -> "Script Recording and Playback", etc then go to the file which is saved in your local SAP directory and see what SAP did.
Hope this helps
