how to change the URL of the web dynpro application

Hi Expert,

I'm new in webdynpro, try to create a webdynpro application..but face error below when test on the application:

The URL does not contain full domain specification (qsndev instead qsndev. <domain>. <ext>).

Thus, I add the full domail name in the icm parameter in RZ10, but it still not working.

Can I change the URL at the webdynpro application under "Administration data" ? How to do that ?

Thx

Janice
