(102) RFC_ERROR_COMMUNICATION: connection closed without message

[former_member84192]

Hi

I am posting an error I get, for which I have seen several posts already but none with a documented solution.

I have an HTTP -> XI -> RFC scenario

I have loaded a BAPI from the backend R/3 (4.6C) in XI. All is working fine, in SXMB_MONI the messages is succesful, bu it fails when RFC adapter tries to call the receiver adapter to call the BAPI

I have remote enabled FM etc, I think the error lies in the RFC receiver adapter definition, but I can't see where I have it wrong.

hostname, system number, user, pass, etc. are set correctly. It must be something else.

Here is the exact adapter error:

Delivery of the message to the application using connection RFC_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while executing ZBAPI_SET_IDOC_STATUS:com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: connection closed without message (CM_NO_DATA_RECEIVED): com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while executing ZBAPI_SET_IDOC_STATUS:com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: connection closed wi

I am beginning to believe that RFC receiver adapter from XI 7.0 (unicode) to R/3 4.6C (non-unicode) is not working.
