Web Dynpro for ABAP or Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web applications in the ABAP environment. It consists of a runtime environment and a graphical development environment with special Web Dynpro tools that are integrated in the ABAP Workbench (SE80).
Web Dynpro offers the following advantages for application developers:

● Strict separation between layout and business data
● Reuse and better maintainability by using components

Note that stateless applications are not possible.
● Automatic data transport using data binding
● Automatic input check
● User interface accessibility is supported
● Full integration in the reliable ABAP development environment
