Functionality that is frequently required should be made available from a standard library of services. For example, if the user is asked to enter a date, then a date picker should automatically appear next to the input field without requiring extra coding effort on the part of the developer. With this approach, the developer tells the development toolset what should be done, but not how to do it.
This concept should extend into all areas of application design e. Web Dynpro is both a development tool for Web-based applications and a runtime environment. It achieves these dramatic savings by using graphical and declarative programming techniques.
The only code developers need to write is that related to the core business process. The power of Web Dynpro lies in its use of object-oriented OO design concepts. Using these concepts, you can create reusable units of business functionality that you can snap together to form a complete application.
We could snap each brick together and end up with, well a rocket or a boat. This would be where you can tell exactly how old I am. When the World Wide Web boom started in the late s, several things rapidly became clear:.
This was the motivation for SAP to go back to the drawing board and create a new UI development environment. By definition, it could not be based on anything SAP had done before.
With Web Dynpro, think revolution , not evolution. It has some similarities to other Web development toolsets, but on the whole, Web Dynpro requires a new way of thinking that, when grasped, will enable you to write efficient, low-maintenance business applications in less time than before. The tools of the New ABAP Debugger are optimized for the different debugging situations you may have to deal with during the course of solving a problem.
Before we look at a few of the tools and how to use them, lets first get comfortable with the tools menu and how the tools are organized.
The controller formats the model data to be displayed in the view. It processes the user entries made by the user and returns them to the model. The component is the global unit of the Web Dynpro application project. Creating a Web Dynpro component is the initial step in developing a new Web Dynpro application. Once the component is created, it acts as a node in the Web Dynpro object list. A standard output consist of header, tool bar and an output table and user can make the settings to add column display, aggregations, sorting options using additional dialog boxes.
It support many properties of table element as it is based on Web Dynpro table UI element. Using filters you can limit the data in ALV output.
You can create multiple number of filter conditions for each field. Web Dynpro trace tool can be used for checking the errors and problems in Dynpro application. You can activate Web Dynpro trace tool for a specific user.
Information is stored about Web Dynpro application and is stored. You can view this information using T-code: RZ You can use tree UI element to create a tree in Web Dynpro application.
Using drag and drop option. To use in other Web Dynpro components. It is used to generate F4 help for inputs field in Web Dynpro application. It is used to create text is specific language and to provide translation in multiple languages in Web Dynpro application.
It means that at run time, no element or maximum one element can be instantiated. What is Web Dynpro? Less implementation time as use of graphical tools. You can easily change layout and navigation using graphical tools. Easy structure changes. With use of data binding, you can use automatic data transport. Ease of integration in ABAP environment. View This is used to ensure the representation of data in a web browser.
Controller This is used to control communication between Model and view where it takes input from users and get the processes data from model and displays the data in browser. You can easily make changes to layout at later stage. More structured approach to use more than one view.
Request Free Demo. ALV output can be filtered, sorted or you can also apply calculations. User can perform application specific functions using UI elements in toolbar. This allows user to save setting in different views. You can also configure special areas above and below ALV output.
