JOHN is running a multiple-form application. The Customers Form invoked the Orders Form. When the Orders Form launches, it displays orders for only the active customer from the Customers form. Forms exchange data with the GLOBAL.CUSTOMER_ID variable. The Orders Form should be restricted to the orders for the current customer only when the query is issued for the first time after invoking the Orders form. Which built-in helps him do this by setting the ONETIME_WHERE property to refer dynamically to the GLOBAL.CUSTOMER_ID?
