Hi

This is a problem with your Message server configuration. As mentioned by kishore see if you have maintained the entry in services file. If not do it and then restart your SLD and then check.

If the problem still persists then Open your SAP logon for windows. Select the Description of the System say "DEV" and then click on Groups.

In the pop up window that appears Enter the 3 letter system id. In your CASE it should be GMH. Then in the Message server enter the SAP R/3 application server host name and then click on Generate list. If your Message server is fine then you should get a list of logon groups like "PUBLIC" "SPACE" and something like that.

If this doesnt work ask your basis person to set this up for you.

Let me know if you require some more information.

Hi,

add this to your services:

sapgw00 3300/tcp

sapms<SID> 36<systemnumber>/tcp

Replace <SID> and <systemnumber> with your environment.

The problem was on the basis side the IP number of the host must be added in the properties of the Logon Group used for the RFC (in this case the PUBLIC logon group)

By default on a single server setup this is not configured.

Thanks for the assistance.

Hi Brett

Can you please tell how we can find the logon group used for RFC ?.

Mine is a single server on which both abap and java stack run with same sid. Where we have to add the IP as you specified?. Please shed some light on this.

Hi Brett

Did you modify the services file on the system where your J2EE is running. if not do the following.

In the location,WINNT\system32\drivers\etc, Open the file services.

Add the following entry at the end.

sapms<3 letter alphabet what you have given for creating the technical system> <a tab> 36+<Instance number><press enter>

in your case this will be sapmsGMH 36<Insance number>
