Hi,

Add the Service name and port no and in the location.

C:\WINDOWS\system32\drivers\etc\service file.

Add the Host name in the location.

C:\WINDOWS\system32\drivers\etc\host

Then check the group(i.e is public or space) generated in the GUI.

Hi,

Ur port no is the message port no. Ur server name is SDM. So add as sapmsSDM as servicecname .

After adding it then open then the SAP GUI and click the groups button. then give the details of the server ie system id as SDM. This will generate the group as PUBLIC or SPACE..

Hope this helps u . Reward points for helpful answer.
