Error in wizard to create new RFC model: connect to message server failed

[Former Member]

Hi,

I am trying to create a new RFC model in my Web Dynpro project in NWDS. In the wizard, I reach the step where I am required to enter the SAP login information. I then enter the details in the Load Balancing tab and click Next. The error message I get is:

Connect to message server failed

Connect_PM MSHOST=****, R3NAME=*, GROUP=**

LOCATION CPIC (TCP/IP) on local host ***

ERROR service '***" unknown

...

(Note: the *** are client-specific and therefore confidential info so I am removing them).

The thing is, a colleague of mine is also doing the same thing, but he is not encountering this error.

Can someone help me troubleshoot this?

Hi,

Try to ping to the server.

Check the host file file of your system to see it has any ipaddress missing that of your colleague

Hi

The user you use to connect in the RFC should have the authorization to S_RFC. In the Duet installation guide look for the section about defining a system user ID in UME. This section has details about the authorization required for the user.

Thanks
