Hi Team,
Good day!
We have an interface in PI that executes a function module in ECC via RFC connection.
Once in a while (intermittently), the RFC communication fails with this error "RFC_ERROR_COMMUNICATION - Connection closed without message".
Response Catalyst Lookup XML:
<rfc:ZGET_LOOKUP_MULTIVALUES.Exception xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<Name>RFC_ERROR_COMMUNICATION</Name>
<Text>connection closed without message (CM_NO_DATA_RECEIVED)</Text>
</rfc:ZGET_LOOKUP_MULTIVALUES.Exception>
Does anyone know what could be causing these intermittent RFC connection failure?
Should this be resolved by increasing the maximum number of connections in the PI RFC channel?
Our statistic shows that 1 for every 1000 messages fail due to this RFC connection failure.
Please advise
Thanks,
Carlo
Hi Carlo,
The issue could be produced for network issues, the intermittent problem seems be related with this.
Check if this note can be applicable to your system 2274565 - JCo: Long running client RFCs interrupted by network issues.
Also, i recommend you to encapsulate the RFCs in a proxy and to use the proxy communication to connect with a ECC. It's a better solution in all the ways, debbuging, performance and from my point of view stability.

The RFC is returning this Exception which means this Exception is occurring in the Application Logic in ECC. I would ask you to check with a ABAPer as to why this happens. Would be worth checking ST22 dumps in ECC as well at around the same time as the lookup fails in PI.

Hi Carlo,
Are you using this for RFC look up?
You can try once increasing no of parallel connections.
Thanks,
