Control inputs change the behavior of an application or the content of a report. In the "Create Report" control screen, the user has the ability to select which reports are going to be produced. This particular screen has several data element types. The check box, graph type, dimensions elements, sub-items and the action keys.
Note that the users can choose each report individually. In fact each report is as an object. The generated report is a combination of several reports (or objects). Each object has several attributes.
