SAP BC --> XI thru. BC Adapter

Hi all,

I'm planning to receive IDOC orders from a BC server with XI. My scenario like this:

R/3 -(RFC)-> BC -(XML)-> XI -(IDOC)-> R/3

But BC cannot send the IDOC to XI and getting the following error in defaultTrace.trc

Could not prepare to receive message due to com.sap.aii.af.service.cpa.CPAException: Couldn't retrieve inbound binding for the given P/S/A values: FP=TESTBC;TP=;FS=DEV_200;TS=;AN=ORDERS.ORDERS05;ANS=urn:sap-com:document:sap:idoc:messages;

I've setup the Business system and corresponding sender / receiver channel. Also the party for alternative identifiers for both Business system ... Any idea ?

Thanks.

Regards,

Maine
