Jco Connection fails through IDT

Hi,

I am trying to create a connection through IDT between BO 4.1 SP04 and SAP BW 740 SP02. but it throws the following error:

    com.sap.connectivity.cs.java.drivers.DBDError: [Data Federator Driver] [Server] [Connector 'testSourceConnection1420804519156'] An error occurred while trying to ping the server: The SAP BW server reported an RFC error: Erreur lors du rappel RFC : Error when opening an RFC connection (CPIC-CALL: ' ThSAPOCMINIT' : cmRc=2 thRc=67

I went through many OSS notes but nothing worked.

Does any one have an Idea?

Best Regards.
