OData-basics

Introduction

.

If any person or company want to expose their SAP Data to an external source like UI5 or Fiori Applications, then they have to Push their data in the form of API (Application Programming Interface). Creation of a link/service that makes sure the data available on the internet with security features is called an OData service. By using this link the authorized authority can do CRUD operations i.e Create, Read, Update and Delete operations. We can apply our specific logic in the respected methods provided via transaction SEGW.
