As I promised @Christian I’m pasting here my approach to connect with SAP. It was always working. I based on that all of my macros for tons of reports from SAP 🙂
Sub SapConn()
Dim Appl As Object
Dim Connection As Object
Dim session As Object
Dim WshShell As Object
Dim SapGui As Object
'Of course change for your file directory
Shell "C:\Program Files (x86)\SAP\FrontEnd\SAPgui\saplogon.exe", 4
Set WshShell = CreateObject("WScript.Shell")
Do Until WshShell.AppActivate("SAP Logon ")
Application.Wait Now + TimeValue("0:00:01")
Loop
Set WshShell = Nothing
Set SapGui = GetObject("SAPGUI")
Set Appl = SapGui.GetScriptingEngine
Set Connection = Appl.Openconnection("01. PRD - ERP Production", True) 'here paste your name of module you are trying to connect/enter
Set session = Connection.Children(0)
'if You need to pass username and password - not connect automatically
'session.findById("wnd[0]/usr/txtRSYST-MANDT").Text = "900"
'session.findById("wnd[0]/usr/txtRSYST-BNAME").Text = "user"
'session.findById("wnd[0]/usr/pwdRSYST-BCODE").Text = "password"
'session.findById("wnd[0]/usr/txtRSYST-LANGU").Text = "EN"
If session.Children.Count > 1 Then
answer = MsgBox("You've got opened SAP already, please leave and try again", vbOKOnly, "Opened SAP")
session.findById("wnd[1]/usr/radMULTI_LOGON_OPT3").Select
session.findById("wnd[1]/usr/radMULTI_LOGON_OPT3").SetFocus
session.findById("wnd[1]/tbar[0]/btn[0]").press
Exit Sub
End If
session.findById("wnd[0]").maximize
session.findById("wnd[0]").sendVKey 0 'ENTER
'and there goes your code in SAP
Hope it will help You 🙂
