SAP GUI Scripting in Delphi - Stack Overflow

I am developing an application in Delphi that needs to interact with SAP GUI via Scripting to automate some material control operations. However, I am facing difficulties in establishing the correct communication with SAP GUI Scripting and executing the desired commands.

Scenario:

• I am using Delphi 12.2 as my programming language.
• SAP GUI Scripting is enabled in the SAP GUI settings and on the server.
• The objective is to connect to SAP GUI, navigate between screens, fill in fields automatically, process transactions, and extract reports.
• I have tried using the SAP Scripting API according to documentation and examples found online, but I still encounter errors.

Issues faced:

• Error when trying to access the session object: some attempts return errors like

  Object required

  or

  ActiveX component can't create object

• Code works in VBA but not in Delphi: I tested some scripts in VBA (Excel) and in a VBS file, and they work fine. However, when porting to Delphi, I cannot reproduce the same behavior.

Example of code used:

uses
  ComObj, Variants;

procedure TForm1.Button1Click(Sender: TObject);
var
  SAPGuiAuto, Application, Connection, Session: OleVariant;
begin
  try
    SAPGuiAuto := GetActiveOleObject('SAPGUI.ScriptingCtrl.1');
    //SAPGuiAuto := CreateOleObject('SAPGUI.ScriptingCtrl.1');
    Application := SAPGuiAuto.GetScriptingEngine;
    Connection := Application.Children(0);
    Session := Connection.Children(0);
    
    // Test: Access a transaction
    Session.StartTransaction('MMBE');
  except
    on E: Exception do
      ShowMessage('Err: ' + E.Message);
  end;
end;

Questions:

1. Am I referencing the objects correctly?
2. Is there any Delphi-specific detail I should be aware of?
3. Is there any additional configuration that needs to be done in SAP GUI or Delphi to allow this communication?
