g_oConnection = oLogonCtrl.NewConnection

g_oConnection.System = AppSettings("SYSTEM")

g_oConnection.ApplicationServer = AppSettings("APPSERVER")

g_oConnection.SystemNumber = AppSettings("SYSNUMBER")

g_oConnection.Client = AppSettings("CLIENT")

g_oConnection.Language = AppSettings("LANGUAGE")

g_oConnection.User = AppSettings("USUARIO")

g_oConnection.Password = AppSettings("SENHA")

Else

'Versao debug sem sap, nao carrega objeto SAP

End If

Catch ex As Exception

MessageBox.Show("Erro na inicialização com o SAP::" & ex.Message, "ERRO 01", _

MessageBoxButtons.OK, MessageBoxIcon.Error)

Exit Sub

End Try

'--- fim 03/03/2005

End Sub

Public Function Login(ByVal Usuario As String, ByVal Senha As String, ByRef Responsavel As String, ByRef Centro As String) As Boolean

funcaoSAP.Exports("I_COD") = Usuario

If funcaoSAP.call Then

Dim ativo As Integer

Dim strativo As Object

strativo = funcaoSAP.Imports("E_RESULT")

ativo = strativo.value

If ativo > 0 Then

MessageBox.Show("Usuario não esta ativado!", "Erro 04", MessageBoxButtons.OK, _

MessageBoxIcon.Error)

Return False

End If

Responsavel = funcaoSAP.imports("E_NOME").value

Centro = funcaoSAP.imports("E_CENTRO").value

Else

MessageBoxButtons.OK, MessageBoxIcon.Error)

Return False

End If

osap2.Connection.Logoff()

osap2 = Nothing

g_oConnection = Nothing

Return True

Else

'Erro na conexão e na validação de dados com o SAP

MessageBox.Show("Usuário ou senha inválidos para acesso ao sistema", "ERRO 02", _

funcaoSAp2.Exports("I_NRSEQUENCIAL") = 1

Dim tabH As Object

Dim tabi As Object

End If

osap.Connection.Logoff()

Catch ex As Exception

MessageBox.Show("Erro na Busca de carga! ( " & ex.Message & " )", "ERRO RFC", MessageBoxButtons.OK, _

MessageBoxIcon.Error)

Return False

End Try

End Function

The proccess running Ok in Loggin Function for my program but in the function BuscaTransporte when I call it in the mmoment witch I send parameters to RFC by exports metod the error is show to me "it´s not member of the structure "EC01".

Can you help me to fix it

[kyo_choi2]

Check the input parameter for the function module that you are calling. I don't see the function BuscaTransporte called anywhere in the code.

[reiner_hille-doering]

If don't know what is wrong with the posted code, but you generally might think of using SAP .NET Connector instead of BAPIOcx.
