CALL_FUNCTION_OPEN_ERROR

[former_member184739]

Hi,

I call a Function module (RFC ) present in BI from ECC. When this FM gets executed it throws the following error.

An error occurred when executing a Remote Function Call.

"CPIC-CALL: 'ThSAPOCMINIT' : cmRc=20 thRc=666#Error occurred in the SAP network

  interface "

Status of connection.... "CODE=CM_PRODUCT_SPECIFIC_ERROR -1 -1 SAPCODE=666

  CONV= "

Internal error code.... "RFC_IO5"

There is an error in the communication system. To clarify

and resolve the error, contact your system administrator.

Last error logged in SAP kernel

But this error occurs less frequently.Experts kindly show some lights on this problem?

Thanks.

Hello Prabaharan,

Meaning of error code 66 is: "GW_NI_ERROR                   666 NI error".

This refers to an error in the network interface. You need to generate a CPIC trace as per SAP note 47682. If it is done, check it and dev_rd for more information.

Hi Adam,

Hello Prabaharan,

If the connection works well in most of the cases and fails only sometimes, it points to a sporadic error in network interface. The root cause of these kind of errors are not easy to find - but let's do it. You need to catch the error and generate the CPIC trace while the error occurs according to the reply above. Until it is done, please attach dev_rd of both communication partners (both BI and ECC) here. I'll review the traces and give you some hints.

Can you paste the output of the command disp+work .

Also check if there is any packet loss  while you do a ping from the ECC server to the BW server and vice-versa.

Also check with the network team for any network issue.

Ensure that your hosts file is correctly configured on both the hosts.
