Unable to assign the connection to TSAPFunctions from TSAPLogon

Hi All,

Unfortunately I didn't find the better category to post the message. Therefore, have chosen this one.

I have got a my own Delphi program connecting to SAP using TSAPLogonControl and retrieving the table data using TSAPFunctions component.

The issue is that it works on our legacy system (SAP R/3 4.6c based) and doesn't work on SAP ECC 6.0 and SAP SRM causing the EOLEException with the message "Internal Application Error".

  Connection                  := SAP.newConnection;

  Connection.User             := AnsiUpperCase(Edit1.text);

  Connection.System           := 'RRO';

  Connection.Client           := '100';

  Connection.ApplicationServer:= 'SAPIDES';

  Connection.SystemNumber     := '00';

  Connection.Password         := Edit2.text;

  Connection.Language         := 'EN' ;

  if Connection.LogOn(0,False) = true then<------ this part works fine and gets into the IF condition. I have set it to False to see which server is exactly being connected.

  begin

    SAPFn.Connection := Connection;<--Error appears here on attempt to assign the connection established at the line above to the SAPFunctions

    SAPFn.RemoveAll;

    Funct := SAPFnc.add('GET_TABLE_RFC');

//  Funct := SAPFn.add('TABLE_ENTRIES_GET_VIA_RFC');

    Funct.exports('CLIENT').value := SAP.Client;

//  Funct.exports('LANGU').value := 'E';

    Funct.exports('TABNAME').value := TabName;

    if not Funct.call then

    begin

      if GrpName='' then showMessage(Funct.exception)

    end

    else

    begin

................................ the rest of the code

    end;

end;

May this happen due to the RFC connection limitations on these servers or due to my user authorizations?

Thanks,
