RFC communication error

687 Views

Hi Gurus,

I created the receiver RFC communication channel.

Im getting the below error in the channel monitoring when PI is connecting to the SAP system.

Receiver channel 'CC_RECEIVER_CHANNEL_UOM_CONVERSION' for party '', service 'GRD'

Error 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) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed

Connect_PM TYPE=A ASHOST=hneccdci01s.glasgow.gov.uk SYSNR=00 GWHOST=saphost GWSERV=sapgw00 PCS=1

LOCATION CPIC (TCP/IP) on local host with Unicode

ERROR partner saphost:sapgw00' not reached

TIME Sun Nov 27 14:08:38 201

RELEASE 700

COMPONENT NI (network interface)

VERSION 38

RC -10

MODULE nibuf.cpp

LINE 4607

DETAIL NiBufIConnect: connection pending after 60000ms

SYSTEM CALL connect

ERRNO 150

ERRNO TEXT Operation now in progress

COUNTER 6

I check the below thread.

RFC_ERROR_COMMUNICATION

The solution is to add the line sapgw00 3300/tcp # SAP System Gateway Port

to the file C:WINDOWSsystem32driversetcservices.

Can you please confirm if I have to add this line in my local PC in the services file located in C:WINDOWSsystem32driversetcservices or it should be added to R/3 system directory C:WINDOWSsystem32driversetcservices.

Also can you please tell which transaction gives the gateway host ,gateway service and gateway port of the R/3 system to which PI is connecting.

Any help appreciated.

Thanks,

Jay.
