Problems for establish connection from IDT universe to infocube on SAP BW 7.3

Hi.

I'm trying to establish connection from IDT to InfoCube on SAP BI 7.3 but it doesn´t work.

The error is about of Data Federator Driver when it try to make the RFC connection wtih SAP BW.

Here the error:

com.sap.connectivity.cs.java.drivers.DBDError: [Data Federator Driver] [Server] [Connector 'testSourceConnection1376499017341'] An error occurred while trying to ping the server: SAP NetWeaver BW has reported an RFC error: Error en la llamada de retorno RFC: Error when opening an RFC connection (CPIC-CALL: ' ThSAPOCMINIT' : cmRc=2 thRc=67

Has anyone ever had this error?

The SAP BO version is SP6 with patch level 3.

Thanks.
