Hi Xherdan,
In the above screenshot , it will set the below parameters
rdisp/mshost: Host name of the machine on which the message server is running
ms/http_port: The port on which the message server receives HTTP requests
If you dont want to use them , you can hashed out the parameters.
So since i have put only gateway's MS name, how will it take the other systems.
Other system will be connected by the web dispatcher with the help of the parameters
wdisp/system_0 = SID=ERP, MSHOST=ms_erp, MSPORT=8182, SRCSRV=webdisp1:80$$
SID = SID of the target system
MSHOST : message server host name of the target system
MSPORT : HTTP Message server port
SRCSRV : you to maintain the port of the target system , to access the HTTP request
With Regards
