Transaction – SE80 (Web-Dynpro-Comp. / Intf.)
Web Dynpro (WD) is a standard UI SAP (User Interface) technology for developing web applications. Another definition for the Dynpro web defines it as an SAP NetWeaver programming model for UI.
Web Dynpro is a client-independent programming model.
- It offers separation of layout and logic and is based on the paradigm of models-view-controller (MVC).
- In the classic MVC, the display gets a direct update from the model, which is without deception through the controller, which does not apply to the Web Dynpro.
- Controller - model and display of links
- View - Defines Frontend (Screen Element)
Basic Concepts
We will consider a basic application for Employee details for explanation purposes.
View
A view is a visible screen area and contains screen elements. E.g. a text field for entering Employee Name
Controller
Each view has a special display controller and each component has a component controller. View Controller Handling the event based on actions triggered in the display. For example. Add employee details by clicking the button.
Window
The window contains one or more appearances. So that the display is displayed in the browser when Runtime, it must be embedded in the window. Windows has incoming and outgoing plugs and global window controllers and are seen by all controllers in a component.
Component
A Components contain all components such as display, controller, windows etc. Needed to run the WD application and act as an application entry point. Components interact with each other through the component interface.
Application
Application is identified by URL (Locater resource uniform) and is something that can be executed for users. When the user calls the URL, WD creates an application root component instance that starts the root component and navigates to the initial display which is displayed in the initial window.
Context
It is a repository of data and is like a data container. Data used in views or components are stored in the context.
Controllers
These are active parts of the Web Dynpro component. The component Controller and Interface controller are responsible for generating data which will be supplied to View Controller for display. Data that can be accessed by the controller are defined in the corresponding context.
A Dynpro (Dynamic Program) consists of a screen and its flow logic and controls exactly one dialogue step.
- Component Controller
- The life span
- Interface Controller
- View Controller processes
Plugs
They can be divided into incoming plugs and outflows. Plugs are used for navigation between various appearances. To navigate from one display to another, the plug out of the call display must be linked to the incoming plug from the display being called. When the display is inserted through the incoming plug, it triggers the event-handling method and thus the event-handling method is produced for each incoming plug.
Scope and Opportunity of Web Dynpro Courses
Courses in this field are very beneficial for the SAP application programmers/ developers. When the application on this platform is run at the front end, they provide easy access to the desired web page, thus satisfying customers with timely solutions for various data needs. Because the SAP module component reduces any industrial implementation efforts, large organizations aim to employ Dynpro web application developers to get efficient work output from the ABAP platform. Therefore, there is an extraordinary scope for professionals in this field and they can see many good opportunities to come.

Web Dynpro for Functional Consultants
In some cases, SAP functional consultants may need to do some analysis of the Dynpro web application whether it is to analyze the eligibility of the building above, again, or only understand the functionality behind it.
In this post, we will discuss some of the basic ways to find tables and methods used in the Dynpro web.
Web Dynpro in SAP
Web Dynpro is a web application technology. When you hear the Web Dynpro, you can associate it with a web-based application or portal. This is mostly used for declarative user interface features. An example is a business user or approval that does not need to access SAP explicitly. Conversely, they can use the portal (Web Dynpro) to do related tasks. All types of transactions carried out on the portal are expected to reflect in SAP.
