primero tienes que instalar el SapConector.Net con el Framework 1.1 y el visual studio 2003, despues crear la DLL en la cual te conectas a sap y crear un proxy y llamas a la bapi.

Luego creas esta funcion que esta hecha en visual basic.net con visual studio 2005 y llamas la Dll que creaste en VS2003 y le pasas los parametros de conexion, no es tan complicado.


Imports DLLSap.

Function Empleado(ByVal ID As Integer, ByVal fecha As String) As DataTable

Dim SapDestination As New SAP.Connector.Destination
Dim SapProxy As New SAPProxy1

Dim dt As New DataTable
Dim r1 = ""
Dim r2 = ""
Dim r3 = ""

SapDestination.AppServerHost = "IP o Host"
SapDestination.SystemNumber = 0
SapDestination.Client = numberclient
SapDestination.Username = "Username"
SapDestination.Password = "Pass"
SapDestination.Language = "ES"

Dim SapConection As New SAP.Connector.SAPConnection(SapDestination)
SapProxy.Connection = SapConection

Dim Emp As New YHR_RFCEMPLEADOS
Dim RFC_Empleado As New YHR_RFCEMPLEADOSTable

Try
SapProxy.Connection.Open()
SapProxy.Bapi_Hrrfc_Empleados(fecha, ID, r1, r2, r3, RFC_Empleado)

dt = RFC_Empleado.ToADODataTable()


Catch ex As SAP.Connector.RfcException

Finally
SapProxy.Connection.Close()
End Try

Return dt

End Function
