Inbound Web Service calls get error "Reliable Messaging(RM) configured, but no Message ID..."

[SAPjedi]

We are setting up the Communication System and Communication Arrangement "Business Partner Replication from SAP ERP".

For protocol, we are using Type 5 - WebServices.  See screenshot below.

Our error is that when we send webservice calls to our C4C, we get messages:

1.  Web service response is "Web service processing error; more details in the web service error log on provider side"

2.  Backend error messages is "SRT: Plain SOAP: Reliable messaging (RM) configured, but no Messaging ID and no WSRM assertion provided"

We have sent messages from PI and also independently thru soapUI.

So it seems the C4C in the backend is stuck on the RM messaging protocol setting.

Appreciate any and all assistance.

Hi Tim,

Please make sure you select Web Service as the Application Protocol in the Communication Arrangement.

Thanks,

I will ask Prakash to summarize the fix.   He and I worked with the PI owner, and the core issue was something deeper.

Yes, make sure the C4C CA protocol is type 5 - Web Service (not type 2).  But the real cause was the PI setup where the customer's PI system had customzied something in the Channel setup.

Prakash, please add a little more info here then, for all to learn from.  Thanks.

Hi Tim,

For this error following are the places that needs to be checked.

1. In C4C the protocol defined in the Communication System should be 5 - Web Services

2. In C4C Communication Arrangement should have the right protocol selected

3. In PI make sure the Communication Channel's are created using provided Communication Channel Templates as part of the standard PI content.

In other words just follow the integration guide available in SMP to avoid such errors.

Hope this helps.

Thanks,

Prakash
