Purav,

The error means that you haven't correctly configured a destination host for the various protocols (!ALL just means show all protocols available). In the Web Administrator tool for Web Dispatcher, if you look in Monitor Server Groups and choose the !ALL tab, you'll probably find no entries, or an invalid entry. The Web Dispatcher finds these groups by various means, but one method is by connecting to the Message Server port for the Central Instance of the system you are trying to reach. In the profile for the Web Dispatcher, you have to configure, at a minimum, the parameter rdisp/mshost with the fully-qualified hostname of the destination message server, and ms/http_port (and optionally ms/https_port) with the ports for reaching the message server via http (or https). I think the defaults on an ABAP instance are 8100 and 8101, if I'm not mistaken, but you configure and activate those ports on the backend system in the instance profile with ms/server_port_0 (for http) and ms/server_port_1 (for https).

Once you get those parameters correct on both backend and Web Dispatcher, this error should disappear.

You can find a lot of information for the Web Dispatcher in Online Help at http://help.sap.com/saphelp_nw70/helpdata/en/c6/0c2c79b9fc4e1c8548815bf56300f4/frameset.htm.
