Hi ravi,

check if the RFC Adapter is properly configured:

1) are the hostname and gateway parameter(sapgw<SID>) correct (the receiver system)?

2) can you ping the hostname (is it visible from XI)?

3) in the receiver system can you see in transaction SMGW -> logged on clients something with the same program ID you inserted in your adapter.

Check this first.

Kind Regards,

Sergio

Hi Ram,

How did you fix this issue? We are having the exact same error message. All the RFC channels worked earlier, but now show the can not instantiate RfcPool caused by: com.sap.aii.af.rfc.RfcAdapterException: error initializing RfcClientPool:com.sap.aii.af.rfc.core.repository.RfcRepositoryException: can not connect to destination system due to: com.sap.mw.jco.JCO$Exception: (102) error.

thanks,

Ravi,

Check if your R3 system is up and running. Check if the firewall is open between your R3 and XI. This seems to be some connectivity issue.

Hi,

1) Check SM59 entries in XI system is pointing to correct R/3 system and test the connection

2) Check the Receiver RFC adapter Configurations- check this - with IP address etc http://help.sap.com/saphelp_nw2004s/helpdata/en/c8/e80440a832e369e10000000a155106/content.htm

3) check gateway services etc.

Related SAP Note- 447882

Also try to restart RFC adapter Engine..from Visual Admin

Hope this helps,
