The Service Builder (transaction SEGW) provides an easy-to-use set of tools for creating OData services. It supports developers throughout the entire development and modeling process.
To use SAP Gateway Service Builder, you must install the Add-On IW_BEP. Depending on your system landscape, you can install this Add-On either in an SAP Gateway system or in an SAP Business Suite system. If your system is based on SAP NetWeaver 7.40 or higher or SAP NetWeaver 7.50 and higher, you do not need to install IW_BEP since the core SAP Gateway component SAP_GWFND 740 or SAP_GWFND 750 is installed as standard and includes the functional scope of IW_BEP. For more information, see Deployment Options.
The Service Builder introduces a new service development concept, which is organized around projects. Projects are used to store the artifacts developers need to create a service and a data model together in one place. Since projects consolidate all related data, developers can easily work on multiple projects in parallel and reuse data between projects before generating and activating the actual service.
