Issue in Creating UNX Universe on BW Cube

Hello,

I am trying to create UNX universe on BW cube using IDT tool. While creating Relational Connection I have selected SAP Netweaver BW(SAP Java connector-SAP JCo). On Next screen , I am providing my BW system details. On the Click of Test Connection button I am facing below mentioned error:-

Error:- “ com.sap.connectivity.cs.java.drivers.DBDError: [Data Federator Driver] [Server] [Connector 'testSourceConnection1420617593288'] An error occurred while trying to ping the server: Could not generate a callback program ID (the last tested ID was 'DF_JCO_AZ18U7496_9'). Delete the unused RFC destinations.”

Please see the attached screen shot of error.

Kindly provide your inputs to resolve this.

Thanks,

Arun
