As of SAP Gateway Release 2.0 Support Package 5, the recommended design-time tool for OData service development is the Service Builder (transaction SEGW). As such the Service Builder replaces the former design-time environment in ABAP Workbench (transaction SE80) as the preferred tool. The Service Builder provides developers with an easy-to-use set of tools for creating OData services and supports developers throughout the entire development lifecycle.
For more information about working with the Service Builder, see Getting Started with the Service Builder.
