Introduction

SAP Gateway and OData are two key technologies that enable SAP applications to share data with a wide range of devices, technologies, and platforms in a way that is easy to understand and consume. By using REST-based OData (Open Data Protocol) services, SAP Gateway exposes SAP Business Suite functionality as web APIs that can be accessed by any programming language or model. This allows you to create innovative and user-friendly applications that run on mobile devices, browsers, or desktops.

What is SAP Gateway and OData?

SAP Gateway is a component of the SAP NetWeaver Application Server ABAP that provides a framework for developing and activating OData services. OData is a standardized protocol for creating and consuming data APIs that builds on core web technologies like HTTP, AtomPub, and JSON. OData provides a uniform interface for querying and updating data across different data sources, such as relational databases, XML files, or web services.

Why use SAP Gateway and OData?

Using SAP Gateway and OData has many advantages for both developers and end users. Some of them are:

• You can leverage your existing SAP Business Suite functionality without having to modify or replicate it.

• You can access your SAP business data from any device or platform that supports HTTP requests.

• You can use any development tool or framework that supports OData consumption, such as SAPUI5, SAP Web IDE, or Microsoft Visual Studio.

• You can create user-friendly and responsive applications that improve user satisfaction and productivity.

• You can reduce development time and cost by using standard protocols and formats.

• You can benefit from the features and enhancements of the latest OData version 4, such as batch requests, delta queries, asynchronous operations, or complex types.
