Asking a question in a case
You can use the Question shape to collect a single response from a user who is processing a case. By isolating individual questions, you can selectively capture user input without the formal structure of a survey.
- 
        Add the Question shape to the life cycle of your case.
        - On the Workflow tab, click Life cycle.
- 
            Hover over a process in a stage, and then click + Step > More > Utilities > Question.
            Tip: For advanced processes, click Configure process to add the shape to the flow canvas.
- Click Select.
 
- 
        Choose a question to ask the user.
        - To reuse an existing question:- 
                In the Question type list, select Rule. 
- 
                In the Question rule field, press the Down Arrow key and select the name of a question. Complex questions are excluded from the list because they are supported in surveys only. 
- 
                Review the information in the Question info section to verify that the question text and answer format are relevant to the case. 
 
- 
                
- To create a virtual question:Use this approach when you are collecting a text response and the question is specific only to the process that contains the Question shape, because virtual questions are not reusable. - 
                In the Question type list, select Text. 
- 
                In the Question text field, enter the text of the question that is displayed at run time. 
- 
                In the Map answer to property field, press the Down Arrow key and select a property to store the value of the answer that the user provides. 
 
- 
                
- To create a reusable question: Use this approach when you are collecting a response in a different format, such as a check box, or plan to reuse the question in another process or survey. 
- 
                In the Question type list, select Rule. 
- 
                In the Question rule field, press the Down Arrow key and select the name of your question.

              functions that are bundled and attached to the harness of the case.
