Example of Virtual Restrictor Usage

In the following example, the Customer Name is specified as a virtual field on the Order Header and is revirtualized to the Order Detail file.

Order Header          Known by            Order No
Order Header          Refers to           Customer
                      VRT                 Customer Name
Order Detail          Known by            Order Line No
Order Detail          Refers to           Item
                      VRT                 Item Description
                      VRT                 Customer No
                      VRT                 Customer Name

This example creates a device design over Order Detail, where Order No. is a restrictor as follows.
