Creating a link between applications

This section shows how to link the update application (updateOrder) with the customer order application (customerOrder). This link enables you to update or edit some of the values in the customerOrder list when it is deployed to a mobile device. In this case, the Quantity variable was set to “update” in updateOrder, so the Quantity column can be updated.
