Not able to select resources in SAP TM NWBC

Hi Experts,

I am facing an error in SAP TM NWBC. I have created the resources in SAP GUI, but while accessing them from NWBC it gives an error that "Vehicle resource not found" even though the resource is available in the drop down selection list.

Kindly help. The screen shots are appended below :

Thanks & Regards,
