Service development takes place in the SAP Business Suite backend system. RFC BOR WF SPI HTTP Consumers Advantages of this scenario: • Routing and composition of multiple systems is supported • Single point of access to backend systems • Hub system can be based on a newer release (7.31 or 7.40) that supports additional authentication options (Kerberos, SAML Browser protocol) • Hub system can be based on a newer release (7.31 or 7.40) that supports SAPUI5 • Enhanced security because of no direct access to the backend system • Direct local access to metadata (DDIC) and business data, meaning easy reuse of data BW GENIL OData Design Time & Service Provider Runtime IW_BEP or SAP_GWFND RFC

Additional security component needed for extranet scenarios. HTTP Consumers Advantages: • Less runtime overhead as remote calls are reduced Disadvantages: • If multiple SAP Business Suite systems are used, SAP Gateway system would have to be configured multiple times • If embedded deployment is chosen, the system must not be used as a hub for additional backend systems. As a result Routing and composition cannot be used. • Upgrade of components in a SAP Business Suite backend system is usually only possible once or twice a year for larger companies BOR WF SPIBW GENILRFC OData Runtime & Design Time & Service Provider Runtime GW_CORE and IW_FND or SAP_GWFND IW_BEP or SAP_GWFND
