RFC connection problem during SRM - R/3 integration

Former Member
0 Kudos

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

Hi,

It will be very difficult to solve without being on the customer site and having all information.

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

Kind regards,

Thanks Yann,

You are right. It seems a network problem.

We can connect to R/3 via Remote Logon. But for example after we go to ST22 to check the runtime errors, the connection dies.
