1Z0-141 Question #16: Real Exam Question with Answer & Explanation

You are running a multiple-form application. The Customers form invokes 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 orders for the current customer only the first time a query is issued after invoking the Orders form. Which built-in helps you do this by setting the ONETIME_WHERE property to refer dynamically to the GLOBAL.CUSTOMER_ID?
