how can i debug a rfc being called from .net connector (NCO) v2.0?

we are having an issue with this process in ecc 6.0. we are not receiving data correclty. is there a way i can view the process / data in sap as it is being called? i want to be able to see the data that is being sent from the c# program thru NCO, sap .net connector.
