Starting the Wizard To start the wizard, position the cursor on the Web Dynpro component to be edited in the object list at the left margin of the workbench window. The wizard is started and leads you through the creation process. Choice of Controller On the second dialog window of the wizard, you can choose whether the service call is to be embedded in an existing controller or whether a new controller is to be created for this purpose.

Service calls can only always be embedded in global controllers — that is, in the component controller or in additionally created custom controllers. It is not possible, to embed service calls in view controllers. Select radio button Use Existent Controller b.
Press Continue. Service Type and Service Selection a. You now select, which service type should be used for this service call. Any framework works on the MVC principle.

However, in case of a Web Dynpro framework, the design data separation is reflected by the objects producing data and the data consuming objects. Meanwhile, the entire structure is designed with components. The user interfaces can be developed in the WD4A framework by two techniques: the declarative interface, when the structure is known before the runtime, and dynamic, when the interface structure is partially known at runtime.
One of the advantages of the Web Dynpo framework in the web development is the web dynpro components reuse in other components .
Therefore, the components are similar to the classes in object-oriented programming. They can be instantiated, but cannot be used as types and classes and, similar to the classes, they do not use the concept of inheritance. Faceless Componentization Structuring Technique The stages of developing such a complex project according to the faceless technology are: implementation and training components for enabling the structure, as well as component structure preparation by making the 3 components - view, model and controller; linking the components for enabling the structure and decoupling in the visual model is also important.
First of all, the faceless component of a project contains nodes which are common to several components used for the project. They also contain other nodes, nodes that we want to be visible in order to extend the project.
It also contains some popular methods of these nodes supply methods and logical methods belonging to the project after the last phase of design and implementation.
The link between the Model Faceless component and the visual View component is enabled according to the MVC paradigm, through the Controller component. It has some advantages, such as: entrusting the project to several design team members, modelling and structuring the project, and reusing all the components. Thus, the Web Dynpro project consists of a number of Web Dynpro components controller, model and view. In such case, the controller is the main component that connects both model and view, and which contains the Web Dynpro application.
For better maintenance of the project, as well as for properly expanding and allowing the component reuse in other projects, we would rather build the logic within the component model. This requires a greater programming effort, and we perform it only if necessary i. The link between them is made by the controller. The benefit of such a design is that it enables developing different views of this same information and reuse components containing these views.
Within a system developed in accordance with the MVC design pattern, the individual components are independent of each other and may be modified and extended. Using the MVC design, we reduce the development time of an application, by reusing all its elements and using less time and effort for enabling the project maintenance. Therefore, it will also take over all its benefits. Thus, the component structure contains a component view, a component model, and a controller component that connects them.
Project organization in terms of technique faceless component structuring The goals of the project can be clearly divided into components. Each component should visually resolve such an objective. Therefore, the project planning may be effective. By dividing the project requirements, we are able to develop independent components. Thus, the work can be also entrusted to all the team members.
Also, the team can be effectively selected, based on its member skills. The software development cycle of the project can be easily done. The project development stages can be clearly delineated according to their activities: local components development and testing, preparing components for segregation, making component structure and binding components to the structure, decoupling the data model of the visual design and testing the project.
The project management is obvious because it is possible to control the project by intermediate testing.
By decoupling the data model of the visual, the logic control of the project is concentrated on the model element, so that any change required by the client in the intermediate stages can be easily performed as far as the codes are concerned, according to the appropriate methods, and since the nodes population with the data of the model component are obvious throughout the project. Project Change from the Faceless Technique Point of View The Faceless component structuring enables changing both the logical and project level, as far as the visual components are concerned.
We can add new components to the component structure, or to remove some structural components by detaching them. Thus, the maintenance and further development of the project may be done effectively within a team.
So far, we conclude that the faceless component structuring technique is a good strategy for the IT project management. Conclusions The Web Dynpro is one of the leading technologies used for the development of Web applications from a SAP integrated high quality system, and the faceless component structuring technique is based on the MVC Model View Controller concept, which is the best strategy, both in terms of management and strategy software. The experiments we have described show that the faceless component structuring technique of a Web Dynpro project is a powerful strategy for the IT project management.
Using this technique, we can achieve very complex projects through teamwork. The project is divided into components that can be individually made and tested. We can easily manage the project during the implementation phases.IS Project Portfolios: This will only display an ALV grid for displaying the data. We have four possible values: Web Dynpro Wizard In this case, the Wizard generates the Table UI element and we use the same procedure presented hereunder to create the data binding.
And enterprise management software should generate itself and promote the value of the environment for cooperation. A node or attribute can be created in each context. The experiments we have described show that the faceless component structuring technique of a Web Dynpro project is a powerful strategy for the IT project management.
