You can automatically create screens that are populated with data from the data source by dragging and dropping the data source onto the Flow Design.
Set the preferences for automatic screen creation in the Device Application Designer Preferences. These preferences allow you to decide which screens to create when you drop a data source onto the Flow Design canvas.
The Relationship Automatic Screens options means that all sub-screens are created after creating the initial relationship screen. This option is disabled if the Relationships screens is not selected.
If you drop more than one mobile business object onto the Flow Design canvas, only the main screens are created. If a screen has multiple screens that can be created, you can use the assist option at the top of the screen to create the screens.
