Using Subscreens on Report Selection Screens

This report shows an example of how to have a tabbed selection screen as part of your report selection screen. This is done using subscreens, and is only available in the 4.X series (I have only tested it on 4.6 systems).

This example is the start of a BDC program, and separates the different selection criteria onto different pages.
