This is a screen capture of Data tab of the Data Mapper. In this illustration, the fields of the Statistics business object display. One of these fields is count30d. Because the Statistics business object has been selected, the Data Mapper has generated a list of its fields, which it lists under the heading, Statistics. The Data Mapper has another section with the heading, Metric Component Fields. This section has a single field, Value. The Data tab also includes the Live Data Preview, which displays the UI in its current state and simulates the runtime experience by showing mock data for the mapped components. In this illustration, no fields have been mapped (the Value field is empty), so the UI in the Live Data preview show placeholder values.
