You must create a new Enterprise Server instance, configured for MSS, for the ACCTWEB application.
To create the server:
If it is hidden, click View > Server Explorer.
This opens the home page of Enterprise Server Administration (also called MFDS) in the IDE.
Alternatively, you can open the Enterprise Server Administration from the Start menu - click Start > All Programs > Micro Focus Enterprise Developer > Configuration > Enterprise Server Administration. This opens Enterprise Server Administration in a browser outside of the IDE.
This displays the Enterprise Server Administration home page with your new ACCTWEB server in the list of the available enterprise servers.
