Business Partner Replicatione Error PI- C4C

Question

Hello everyone,
i've done a Business Partner integration CRM - C4C with PI.
The exchange of business partner works already but i get a strange error message in the web service monitoring.
It says:
com.sap.aii.af.service.cpa.CPAObjectNotFoundException: Couldn't retrieve inbound binding for the given P/S/A values: FP=;TP=;FS=<my communication channel>;TS=;AN=BusinessPartnerReplicateConfirmationOut;ANS=http://sap.com/xi/AP/CRM/Global
But this error encounters only at the second time the cloud sends a SOAP message from C4C to PI (See the picture).
Then i've checked the Payload and the only difference between both payloads is that in the second one (which ends in an error) has an additional internal ID
First SOAP Message (green one):
    <BusinessPartner>
      <ReceiverInternalID>5000191338</ReceiverInternalID>
    </BusinessPartner>
Second SOAP Message with error:
   <BusinessPartner>
      <InternalID>5000191338</InternalID>
      <ReceiverInternalID>5000191338</ReceiverInternalID>
    </BusinessPartner>
The Business Partner has the correct Account ID (5000191338).
So my question is, what does the error say and how do i get rid of it?
Regards,

Hi Raphael,
for some interfaces you will see 2 messages that represent a kind double step:
the first message seems a kind of internal step, I mean internal message exchange inside C4C. What I have realized in this step is that code list mapping, if any, will be executed.
the second message is the message that actually is sent to SAP PI.
Looking at your error it seems that you are calling the SAP PI webservice in the wrong way. You have to fix query parameter in the URL, in other word you have to fix the PATH that you have in the Communication Arrangement (CA) Tech Details.
In your case, your CA should be Business Partner from SAP Suite. Open this CA (edit button), then go to Technical Data--> Edit Advanced Settings.Select Outbound tab and select the only one service Confirm Business partner etc etc
Fix the PATH string.
The below path template should work:
/XISOAPAdapter/MessageServlet?senderService=BSY_C4C&interface=BusinessPartnerReplicateConfirmationOut&interfaceNamespace=http://sap.com/xi/A1S/Global
BSY_C4C is the business representing C4C in your System Landscape.
You can grab the right parameter for this string looking at the header of the sap pi ICO related to the webservice you wish to call. In your case it should be the one with outbound interface BusinessPartnerReplicateConfirmationOut and sender system your Business system representing the C4C.
Also make sure those parameters are in the sender SOAP communcation channel.
