  1. 1. Mobile Solutions with SAP NetWeaver GatewaySyambabu Allu, ConsultantSAP Mobility
  2. 2. Agenda What is SAP NetWeaver Gateway and oData Overview of SAP NetWeaver Gateway Architecture of SAP NetWeaver Gateway Solution Architecture for Online Mobile Apps Software Components for Gateway System Development Process Demo
  3. 3. SAP NetWeaver Gateway
  4. 4. What is SAP NetWeaver Gateway and what is it not?It is not…… the Gateway component of SAP NetWeaver Mobile.… the SAP Gateway that is part of the Web Application Server ABAP that enables RFC communication.… a mobile platform.… a replacement for SAP NetWeaver PI and eSOA Services.It is…… a NetWeaver Application Server ABAP add-on.… an essential part in making an online mobile application, providing access via SUP to SAP Business Suite using the OData protocol.*Remote Function Call **Process Integration
  5. 5. SAP NetWeaver Gateway provides the following functionality …Runtime environment for SAP solutions that integrates desktop programs with SAP systems. …Runtime features, including user interface, secure data access, database connectivity, and network communications for managing applications running on top of the framework. …Infrastructure and tools for developing applications to run on the framework or to enhance SAP solutions that integrate desktop programs with SAP systems. …Connection to multiple SAP systems regardless of their versions.
  6. 6. Open Data Protocol (OData)It is a non-proprietary license-free web protocol for querying and updating data.It offers database-like access to business data (“ODBC for the Web”).No prior knowledge of SAP required.Dynamic binding takes place at runtime.OData is based on HTTP(S) communication and the Atom Publishing Protocol(AtomPub).For more detailed information, please refer to
  7. 7. Open Data Protocol - “ODBC for the Web”OData can be used to access table like structures much the same way ODBCdoes.

  18. 18. SAP NetWeaver Gateway Service Builder(SEGW)  Developer productivity (low TCD) for ABAP Developer The SAP NetWeaver Gateway Service Builde provides a tool to centrally display and create the definition of an OData Service. -Runtime artifacts (model provider class, - data - OData artifacts (entity set, entity type and properties) -provider class, model and service) - Used data sources and models  EDMX-Model import  DDIC Import
  19. 19. Multiple Origin Composition Access data from multiple backend Systems with one service call.  Add multiple aliases to the service in transaction /IWFND/MAINT_SERVICE.  Add “;mo” to the URL of the service. - Example: http://<host name>:<port>/sap/opu/ odata/iwfnd/RMTSAMPLEFLIGHT;mo  More information on the Help Portal.
