IDOC and RFC sent by SAP PI , how to access in ECC.

Hi Everybody,

I have been working in SAP PI but have never handled the ECC part of the implementation.

Till now I have only dropped idoc or RFC to the ECC system and let the further processing to the target team.

But in new project the further processing part also we have to handle.

So could you please tell me, for any idoc (say ORDERS) once PI drops it at ECC , where to access it ? which table? for further processing of that data in ECC? Same for RFC?
