How to Extend a Fiori Application: Purchase Order Approval

This guide will show how to extend a standard SAP Fiori application using SAP Web IDE. We will create a new extension project using the SAP Fiori Purchase Order Approval app from SAP Gateway and extend the app by hiding an existing control, adding a new UI field to an extension point, replacing a view, extend the existing OData service in Gateway Service Builder, replace the OData Service by an extended OData Service, extend the data model using the EDMX editor, add a reference to the new data property in the UI logic. At the end, deploy the application to SAP Gateway and verify successful deployment.
