- Data transport is automated using the data binding process.
- Automatic check for input.
- Automatic operation of the Web Dynpro application using the keyboard.
- User interface accessibility is supported in Webdynpro.

SAP ABAP Web Dynpro Configuration:
Before we start developing the Webdynpro application, the below configuration settings have to be done properly:
1. We have to install the Application Server ABAP (AS ABAP).
2. ICM (Internet Communication Manager) — HTTP or HTTPS must be set in ICM. We can configure it on the initial screen of the ICM monitor by selecting ‘Services’.
3. ICF (Internet Communication Framework) — ICF services must be activated if not use transaction SICF to activate the services related to WDA. Proper authorizations should be assigned to the ICF server and client functions.
4. View Designer — To create the layout in layout editor in the view designer we have to activate all the services in SICF for WDA.
5. SSO (Single Sign-On) — SSO must be set up on the application server.
6. FQDN (Fully Qualified Domain Names) — Avoid shortened FQDN. We have to check whether the URL for the WDA application contains the full domain and hostname.
