As support for our daily tasks, we add here some of the transactions we use in this book Fig. Add Other Objects Fig. Download to PC to save on our computer a list with all the objects we have in the Favorites folder. To upload in a Favorites folder objects from a list saved on our computer, we can use Favorites! Upload from PC. Set start transaction Fig. By using this logon, we can login into the system. A SAP shortcut allows us not only to perform a logon into the system, but to execute other commands, too.
So, we can start a SAP transaction, run a report or perform a system command. To create a SAP Shortcut on our desktop to start the transaction SE80, we can use the Wizard available in the layout menu, by clicking on the respective icon located in the system function bar Fig.
Create Shortcut on the Desktop.
Gellert and A. Here, we develop not only Web Dynpro applications, but also other development objects e. After creating the package, we create a Web Dynpro component, as follows: right-click on the package name and, from the context menu, we select Create!
Web Dynpro! Web Dynpro component. We have to enter the component name, a short description, the type we want to create, the view name and the window name Fig. After creating the Web Dynpro component, we have to activate it Fig.
Each View has a view Layout, where we can add different UI User Interface elements that can be nested one in the other one, to create the screen.
The positioning of the UI elements in a view is realized by using the layout and data layout. This indicates that a View consist of many parts. We have several ways to add an UI element into the view layout. In this way, we can change the properties of each element. As a result of changing the property state of the InputField UI element from the Normal item to the required one, the label associated to this UI element becomes a red star and the end user knows that this value is mandatory. For a property, we can create fixed character strings, we can choose from a list, or we can bind properties to context nodes or attributes by using the Binding button.
For the design property, we have chosen from the list one of the supported designs. To be able to do this, we will create two context attributes. In standard mode, the web Dynpro Framework offers the default context menus with certain functionalities, e. After running the application, we can test this standard mode by rightclicking on the inputField UI element.
Every View has a Context View where we can create context nodes and attributes. Via data binding, the context of a view controller provides a view with all the required data.
To put the data on the screen and to read data from user, we connect the proper UI Elements properties with attributes or nodes. These connections are known as data binding Fig. To do this, we use the Action tab Fig.
After creating an action, we can assign it to an UI element that has attached an event Fig. In this way, we can insert the source code.
After this, we reset the inputField UI element. For more details about Methods, please see Chap.
In this tab, we can set the view lifetime: l l Framework controlled — controlled by Framework When visible — lifetime limited to its visibility. A view controller is always deleted as soon as the corresponding view is no longer displayed on the user interface.
It is used when a view is displayed only once and not repeatedly. Additionally, Property tab offers the possibility to define the usages Fig. Create Controller Usage 22 3 Designing a Web Dynpro Component We can define a usage to be able to access the methods of another internal controller or of an interface controller, if the usage has been defined for an external component.
We have to specify that, for each view controller, the usage of the corresponding component controller is automatically created. We can use it, for example, to call a user-defined method. Additionally, we can create our own attributes. Hereunder, in our examples, we will see how we can cross-component access the methods and the attributes defined here.
When the user interacts with a view, their interaction will cause a request to the server.
In response, one or more views that build the current screen will require to be replaced with other views. This is possible through navigation links among the various views in the window. Each Web Dynpro component can have several Windows. A view or several Views are generally embedded in a Window. The first view created at the WD component creation is directly embedded into the Window. In every window, at least one view is marked as default. A default view is the first view displayed when the window is called.
The first embedded view is marked as default, but we can change it. To mark as default, after right-clicking on the view we choose Set as default from the contextual menu.
For a Window, these plugs can be of Standard, Startup or Resume type. No additional import charges at delivery!
