CALL_FUNCTION_OPEN_ERROR in CRM while trying to connect to ECC system

[Former Member]

Hi All,

We are having issues while connecting to ECC system from CRM at specific point of time.

It occurred only once yesterday . Since it is a production system, we need to investigate the cause of the issue.

Upon checking the logs, I can see dumps in ST22 stating CALL_FUNCTION_OPEN_ERROR while trying to connect to ECC.

This issue has been faced by multiple users at the same time.

Both CRM and ECC are in the same server . There are no errors in ECC system ,

The error description says

Error opening RFC connection

Error text........... "Group USER not found"

Description.......... "LgIGroupX"

The response time is fine for the system and during the time when the error occurred.

Both the systems are in kernel 720 patch level 416.

There are no errors in dev_rd and dev_ms as well.

The errors in trace file also give information that ECC system cannot be reached.

However our ECC system was available , up and running and there were no issues at that time with ECC.

I have attached the dump, kernel and patch level details , work process trace files and the response times.

Please suggest.

Thanks,

Sowmya.

It appears to me that the RFC connection PUCCLNT220 is configured with the logon group USER to connect to another system. Check if there is a logon group called USER on the target system.

If there is no such logon group then:

1 - Create a logon group with that name in the target system Tx SMLG or

2 - Reconfigure the RFC with hostname and system number

Hello Sowmya,

Without seeming to state the obvious but have you gone to your ECC system and checked the logon/rfc group USER does exist ?

I both ECC & CRM systems running on the same physical host / in virtual environment (like Xen). If running on virtual environment, please check the OS log if any error appears

[manumohandas82]

Do you have a logon group "USER" in SMLG  on your PUC system ?

Thanks ,

Manu
