Navigation flows in the Web UI is a common requirement. In 11.1.1.7 we do not have out of the box support for navigational flows but this is surely on our road-map.Until then this simple approach might meet some of the requirements. In this sample we use a trigger control and Web Form rules show navigation flow for Customer, Orders and Line Items.

Start by creating  a new Web Form and adding 3 tabs as Customer,Order,Line Items.Add the elements to each tab.

Change the visibility for Order and Line Items to false

Tab1 : Customer

Tab 2 : Order

Tab 3 : Line Item

N    Notice we have added trigger controls for Next & Back Buttons.

       Now write form rules to change the visibility and selection of tabs based on the clicks of trigger

You can now navigate through the forms using the trigger control.
