Generating a UI Component for a Single Task
Prerequisites
-
You have opened the Process Development perspective in the SAP NetWeaver Developer Studio and have expanded your project in Project Explorer view.
-
You have modeled a process containing human activities.
-
You have created the necessary data objects with data types assigned, which form the process context.
Context
When you model a process, you use tasks to assign them to the human activities in the process. The task is executed by a human. The interaction between a human and the process is enabled through a user interface (UI) component. The UI component assigned to a task allows the user to access and execute that task.
When you model a human activity, you have the option of creating a task for it using the Task tab page in the human activity's Properties view. The task is automatically assigned to the human activity. When you create a task this way, you can generate a UI component for this task. After successful UI generation, the generated UI is automatically assigned to the task.
The generated UI component is based on the process context, which includes the data objects in the process and their data types. Task input and output fields correspond to the selected process context attributes. For more information about process context, see Process Context .
The UI component is generated automatically using either the Web Dynpro for Java (WDJ) or Visual Composer (VC) technology. The UI component is created in a respective development component (DC), which is either WDJ or VC DC. You can create the UI component in an existing or in a new DC. For more information about creating development components, see Creating a Project .
When the UI component generation completes successfully, a dependency is automatically configured from the DC containing your process to the DC containing the generated UI component. You can check this dependency when you open the Development Infrastructure perspective. For more information about development component dependencies, see Defining Development Component Dependencies .
After you create a task and generate a UI component for it, you can edit the task and specify task owners, user texts, time constraints, and so on. You can also change the task attributes for the particular human activity, to which the task is assigned.
Procedure
- Select the process context attributes on whose basis the UI component is generated. Choose the
Finish pushbutton.Caution
Some data types of the process context are not supported and you cannot select them. For more information, see SAP Note 1337578
.
Results
The task is created together with a UI component and assigned to the human activity. You can view the task in the
Tasks node in the
Project Explorer view and edit it in the task editor. You can open the
Web Dynpro or
Visual
Composer perspective respectively, to view the generated UI component. To do that, you choose
Window 
Open Perspective Other 
and select the relevant perspective.
If you choose to generate a Visual Composer UI for the task, and you later modify the Visual Composer model without deploying it in Visual Composer, you must choose Validate in the Visual Composer Deploy task panel to be able to view the generated Visual Composer UI in Business Process Management.
You can check the automatically configured DC dependencies when you open the Development Infrastructure perspective, select the DC containing your process and open the Dependencies tab page.
