SAP Gateway Foundation for OData V4 Developer Guide

The OData version 4 (V4) standard combines the requirements from existing SAP applications built with the OData version 2 (V2) protocol. Gaps in the OData V2 standards have been filled and concepts have been optimized to fully satisfy the business requirements of SAP applications. The main changes aim to improve processing time and resource consumption on clients and servers and to reflect the complexity of the underlying business model. This includes a lightweight JSON format reducing the size of every response.

Business data can be retrieved in the exact amount, right time and appropriate mode by using new synchronization mechanisms.

Calculations and data aggregation are now done leveraging the tiers best matching for this task.

Sophisticated metadata artifacts enable a true-to-life modelling of business models. Examples are singletons (for one-time entities), containments (for composition of entities), actions bound to certain entity types and new options to define properties.

This guide provides information on the following aspects:

The central design time tool for creating OData projects also offers OData V4 functionality. For more information, see Working on Service Builder Projects Complying with OData V4.
