Some screens rely on data selected in a previous screen. This is true in the JDP Screen Builder. You move from tab to tab, left to right, as you build a screen. The data selected in the "Select a Data Source" screen will appear in the "Select a Table" screen. Once you've selected a table, that information will be available under the "Select Columns" screen, and so on.
When you step down into a new level, a "back" tab automatically appears. If there are too many tabs on one level to fit horizontally, a Right arrow tab will appear allowing access to the other tabs.
