If you select a specific sort sequence for a particular list field, the system automatically provides you with a text at the start of your control level and creates subtotals for the control level's numeric fields.
For example, you have selected the following fields.
This QuickView is sorted according to the fields Airline ID and Flight connection code. After you drag these two fields to the Sort fields toolbar, the control level texts automatically appear above your list fields. Subtotals are displayed below the list's numeric fields.
Whenever you choose a sort field in the toolbox, the display options of its corresponding control level are displayed in the window at the lower left-hand corner of your screen. Here you may also determine a sort direction for each sort field and select options for the beginning and end of the control level.
