Error while communicating with the backend system

[#1]

Hi All,

SRM 5.0 / R/3 4.6c

I get this error ( Error while communicating with the backedn system- inform system admin). when i search for cost centers. I have maintained the dialog rfc user and i have a manager role but still i get this error. Am i missing on any configuration ?

Krishna,

Try this:

In R/3 for RFC user (which you have used in SM59) assign "S_RFC" in its profile:

You can do this by Transaction SU01 --> Profile tab ---> Assign "S_RFC"

Let me know if still this doesn't work.

Hi Yosea,

Try looking in to this note 656633. I have created one more RFC destination SRMSRCHELP in SRM and R/3. In the logon and security tab i have assigned a dialog user SEARCHRFC in both the Systems .then I have assigned this RFC destination in the IMG menu DEFINE BACKEND SYSTEMS.

let me know your case as well.

Hi Khrisna,

I have looked into the notes already and as I understand the problem happened because the RFC user is not a dialog user. So rather than modifying the table in config for define backend system, we simply change the RFC user to be dialog user in R/3. And it works now.

But I have a small doubt. Can we really use "dialog" user for RFC user in R/3? What is the drawback on that?

Yosea.

Try setting up one more RFC destination like SRMSRHHELP and assign SEARCHRFC user to it in both the systems. and populate the define backend systems IMG task with the SRMSRCHHELP. This is what will be done usually. If you go with these settings you dont have to maintain your system RFC user as dialog.Instead you can maintain SEARCHRFC as dialog.

Hope i was clear
