RFC connection problem during SRM - R/3 integration

Hi,

Our environment is SRM 5.5 server with 2 R/3 backend systems. One of the R/3 systems is in another country. We happen to have RFC problems during the communication between the SRM and R/3 server.

Below you can find the SM21 log related to an operation on SRM server. What might be the reason for this problem? Does anyone know the solution?

Many thanks

    Right now, the error code is network error...

    Kind regards,
