SAP calling SAP BC

Hello all,
I have created an inbound map for an existing SAP function module in IS6.1 and i configured a RFC destination,and corresponding RFC Listener for that in our IS.Now When i’m executing that RFC function from SAP,i’m getting the export parameters as null values.I enabled tracing in that RFC destination.

Is there any need for modifying the generated inbound map.
Here i’m mentioning the trace file,and unable to understand the contents.
