SAP Extract into EXCEL via VBA out of memory

Question

I am trying to extract a SAP transaction into a .txt document through a SAP script that I recorded which finally then gets extracted into my excel sheet.

When I run the script in SAP then it works by copying the values into my .txt document. So it seems like my problem is my macro in excel not activating my SAP script.

When I run my VBA macro to do the same, it says

"Run-time error '7': out of memory

and does not copy anything into my .txt document.

I hope someone can tell me why?

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)SAPFrontEndSAPguisaplogon.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 :)
