JCO_ERROR_COMMUNICATION: CPIC-CALL: CMRCV on convId: 02667299

[former_member196171]

Hi Experts,

I am having some issue with PO and ECC connectivity with data load from PO to ECC system via RFC connection

RFC is configured in PO , SOA -> Technical Configuration -> System Connections -> Provider Systems -> Connectivity  as below

from NW 731 PO system  sending data to ECC system via RFC  connection  getting the following error

We are getting this error sporadically,  

Do I have to do anything with the  SLMG log on group for this RFC connection ?

Detail log is attached  too as file attachment

failed outbound processing from PO to ECC.txt.zip

[former_member196171]

this was resolved after changing the connection from log on group  to  CI instance

Thanks

Hi, Al.

Thank you for your reply.

Can you please elaborate what does it mean from log on group to CI instance? Does it mean that you remove the application servers from the logon group (via SMLG)?

Cheers,

Hello,

can you check if that logon group is working from sap gui

Regards,

[former_member196171]

Hi

yes , log on group works from SAP GUI

Hi,

Is your PO and ECC system in same network?

Can you increase the gateway timeout value in ECC and see.

Thanks

Imtiaz

[former_member196171]

Hi Imtiaz,

Thanks for your prompt reply

Currently the gateway time out is 0 (default) in ECC,

PO and ECC are not in the same network , but the connections are ok with the ports as tested with telnet.

Thanks

Hi,

I was not clear earlier, please check value of gw/cpic_timeout in ECC.

Also check gw/max_conn, It could be possible that max connections are reached in ECC.

As you are not in same network, please check network statistics to make sure there is no connection breakdown.

Thanks

Imtiaz

Hi Imtiaz,

Thanks again for your reply.

gw/cpic_timeout is dynamic and I have increased to 40 from 20 , and gw/max_conn is already set to 4000.

To isolate the problem,  I have also removed load balancing with  the connection, now directly with CI only. This is  production, so I  have to wait till next data load.

I will update with the result

Thanks

Hi Al,

I have the same issue.

Can you please share it to me what was the solution?

Thanks,
