Referencing Data Source

You can reference a Data Source in Service Builder and create a desired model.

Introduction

Data Source Reference: Artifacts in Data Source References are imported via reference option in the project builder. Such artifacts are not persistent in Service Builder, instead when Service Builder is open they are fetched via reference unlike artifacts imported via other methods in Service Builder. Hence, these are always dependent on the status of the data source availability. Their behavior and operation is controlled by the Data Source Reference Provider and not by SAP Gateway Service Builder.

Note As these services are referenced, they are always Read-Only.

Brief Overview

While referencing a data source, any modification expected is done and defined by Data Service Provider instead of Service Builder. It includes interaction between various entities which may be imported through different data source reference providers.
In case of any inconsistency between Entity Types and referenced data source, user has to act on it. No automated correction is available.
If you redefine these services, having one or more referenced entities, Redefinition behavior is same as to the conventional redefinition scenario.

Reference option in Data Model sub-menu is used to load entities and other supported artifacts from the referenced data source to your project. Data Source Reference option enables you to reference the data model instead of maintaining in the service builder.

Pre-Requisites
