Freely Programmed Value Help in the WebDynpro application (WebDynpro for ABAP)

By RameshKumar Raamasamy, Kaavian Systems

Web Dynpro ABAP Framework allows you to create your own input help components. A component to

 be used as value help must implement interface IWD_VALUE_HELP (see Working with Web Dynpro Component Interfaces). Once the freely programmed value help has been linked to a context attribute, the value help is automatically available for every Input Field linked to this attribute.
