Hi Experts,

I have a HTTP - RFC scenario, where in response message for RFC  I am seeing the below error.

com.sap.aii.af.ra.ms.api.DeliveryException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not get a client from JCO.Pool: com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=A ASHOST=XXX.com SYSNR=02 GWHOST=XXX.com GWSERV=sapgw02 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner XXX.com:sapgw02' not reached TIME Tue Jan 27 10:39:22 201 RELEASE 701 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nixxi.cpp LINE 2835 DETAIL NiPConnect2 SYSTEM CALL connect ERRNO 79 ERRNO TEXT Connection refused COUNTER 3

Is it because of the the gateway connectivity issue..

Regards

Kiran Kumar.P

Hi Kiran,

Add your Gateway Service in your Services file and try again .

example:

sapgw00          3300/tcp                           # SAP System Gateway Port

To the File C:\WINDOWS\system32\drivers\etc\services

also refer the link http://scn.sap.com/thread/24853 for more details

Hi,

Check the RFC Destination created in ECC and make sure that you have assigned the correct gateway and host details.  Maintain same gateway and host details in Channel Configuration.

Thanks,

Above error normally occurs when unable to establish connection ...

so check the connection details and the system availability ..

Also are you sure that the above message is occuring for Response ?

Check the status of your RFC Channel

Hi Kiran,

It might there are not  available connections in the RFC receiver channel. Try to increase the Maximum connections parameter in the RFC channel.
