This video discusses the different ways to consume Core Data Services (CDS) views in the OData service. It covers three main methods: through annotations, importing in the SEGW project without manipulating the data using DPC class, and importing in the SEGW project then manipulating the data fetched from CDS view using DPC EXT Class.
After watching this video, you will learn:
1. How to consume CDS views in the OData service using annotations. This involves creating a CDS view and enabling it for UI applications using the annotation “odata.publish: true”. The video demonstrates how to activate the service and test it in the browser.
2. How to import a CDS view into the SEGW project without manipulating the data. This method doesn’t require specific annotations in the CDS view. The video shows how to import the CDS view, use the standard DPC class, generate the project, activate the service, and test it in the SAP Gateway.
3. How to import a CDS view into the SEGW project and then manipulate the data fetched from the CDS view using the DPC EXT Class. This involves redefining the DPC extension class and writing code to manipulate the data after it’s retrieved from the CDS view.
The video is practical and detailed, showing each step at the system level. It is intended for those who wish to learn about CDS Views and how to consume them in OData services.
