When two blocks are linked by a master-detail relation:
Master and detail blocks can often appear in the same window or they can each appear in separate windows. When querying the details may be slow (usually when they are in separate windows), an unlabeled coordination check box appears in the upper right corner of the detail block window. This check box lets you decide whether to constantly update the coordination of records between a master and a detail window when the detail window is open in the background.
Figure 1 - 37.
For example, suppose you have a master and a detail window, and the detail window displays records that pertain to the current record in the master window. If you uncheck the coordination check box and then display another record in the master window, the detail window clears itself and does not display any data until you move your cursor into the detail window. At that point, it displays the detail record(s) that match the current master record. If you check the coordination check box and display another record in the master window, the detail window automatically refreshes to display the detail record(s) that match the current master record.
Note: When you first open a detail window or when you query a new record in the master window, the detail window always updates to display the detail record that matches the current master record regardless of whether the coordination check box is checked or unchecked.
