How to see the processing of service?

How to see the processing of service? I know the process, have read in documents.but I wanna to see the process by running it.I have some confusions in running.Can anybody tell.Thanks

tn:receiver service you cannot debug it.

But ofcourse you can the functionality (tn:receive) will route any EDI/XML/Flat File documents to TN

Basically you need to map the node input for (sending XML documents to TN and for EDI just map “edidata” from the upstream variable to it.

Please review the TN built in services guide on what inputs you have to map before you test or route documents to Trading Networks.
