In WD, the context of the global component controller are not automatically available to other controllers. In normal programs, the global variables are automatically available in all subroutines. Similarly in WD, the contexts for the initial view(s) are usually defined at the Component Controller Level (as they are global). In most cases, the selection screen data are global.

Usually, normal program has selection screen parameters and select options. Like any normal program, you should first define the Types and Data (variables, internal tables, work areas), i.e.in WD, you should declare the contexts. What are the steps to start a Web Dynpro assignment? All the extraction, massaging and modelling should be done in the assistance class. But the most commonly used ones are:Īssistance Class is the “M” of the famous “MVC”, Model View Controller. There are numerous UI elements in WD ABAP. Some of them are:Ĭontext node Internal Table/Structures/Work AreasĬontext attribute Fields of variables ( single field or fields of structure / internal table )Ĭomponent Controller TOP include program ( declare global variables )Ĭustom/View Controller Sub routine ( declare local variables ) We can make vague analogy between Web Dynpro terms and classical ABAP terms for simplicity. This would be different than others and would just concentrate on the basics and some practical tweaks and tricks. There are tons of materials already available for theories and practice.
FREE WEB DYNPRO SERIES
This series would not give you detailed theories.
FREE WEB DYNPRO HOW TO
We would hand hold you and provide you some actual project requirements and how to achieve them. This series would act as a launching pad for our readers to develop their initial Web Dynpro applications. In this post and the series to follow, we are planning to provide the concepts to understand the basics of ABAP Web Dynpro. It is like any other area of SAP ABAP, which helps the developer to achieve the requirement and deliver some cool applications. So, neither under estimate it nor be scared of it.

Web Dynpro: It is neither a tool with only drag and drop ( those who have actually not worked would say this) nor is it something only for the Geeks ( some who have worked might flaunt). A very popular book on “C” at our part of the world. The title is inspired from the book “Let us C”.
