Error During Test Connection to CRM on-Premise

Hi,

while doing a Test Connection, while creating a communication arrangement, the system give us the following output

so everything seems ok, but the return message seems to not be correctly received.

While looking into response, we can see the following message

<SOAP:Fault xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>SOAP:Server</faultcode><faultstring>Server Error</faultstring><detail xmlns:s="http://sap.com/xi/WebService/xi2.0"><s:SystemError><context>XIAdapter</context><code>ADAPTER.JAVA_EXCEPTION</code><text>

com.sap.aii.af.service.cpa.CPAObjectNotFoundException: Couldn't retrieve inbound binding for the given P/S/A values: FP=;TP=;FS=<hour host>;TS=;AN=CheckConnectivityConsumer;ANS=http://sap.com/xi/CommunicationServicesManagement/Global;

  at com.sap.aii.af.service.cpa.InboundRuntimeLookup.&lt;init&gt;(InboundRuntimeLookup.java:88)

So seems that we shuld create a communication arrangement for interface CheckConnectivityConsumer, while seems that is not possible.

The connection is to a CRM system trough a PO system; in addition all communication arrangements seems to work correctly (for example Business Partner replication from/to CRM system).

Has someone already faced this error before?

Thanks

Giacomo
