SAP NetWeaver Gateway

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 enablesRFC 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 viaSUP to SAP Business Suite using the OData protocol.

*Remote Function Call **Process Integration

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.

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 http://www.odata.org

Open Data Protocol - “ODBC for the Web”

OData can be used to access table like structures much the same way ODBC does.

Why REST?

Step 1 (Gateway) • Pick a Dynpro, a BAPI or existing Gateway

Model

• Create a Data Source Model through the Gateway Design Time

• Create a simplified Model and generate the service document

Step 2 (Consumer IDE)

• Create Proxy Classes using Plug-ins

• Create a consumer application

SAP NetWeaver Gateway Service Builder (SEGW)

Developer productivity (low TCD) for ABAPDeveloper

The SAP NetWeaver Gateway Service Builderprovides a tool to centrally display and createthe definition of an OData Service.-Runtime artifacts (model provider class,- data

-provider class, model and service)

- OData artifacts (entity set, entity type andproperties)

- Used data sources and models EDMX-Model import

DDIC Import

Multiple Origin Composition

Access data from multiple backend Systems with one service call.

Add multiple aliases to the service intransaction /IWFND/MAINT_SERVICE.

Add “;mo” to the URL of the service.- Example:

http://<host name>:<port>/sap/opu/odata/iwfnd/RMTSAMPLEFLIGHT;mo/

Summary

Developers with/out SAP knowledge are able to create solutions for SAP Systems

SAP NetWeaver Gateway is required when developing mobile online applications,which enable the access to SAP Business Suite systems using OData Protocol

SAP NetWeaver Gateway is a NetWeaver Application Server ABAP add-on.

SAP NetWeaver Gateway supports every device and platform.

And Much Much More…

More features in SP4… $batch - allows you to pass in multiple operations in a single call

- See http://scn.sap.com/docs/DOC-29682

$inlinecount - includes entity count returned with results of get_entity_set method.

Integration with SAP HANA - make a connection to SAP HANA and expose HANA data as OData Service via Gateway- See http://scn.sap.com/docs/DOC-30428

And More…See entire list http://help.sap.com/saphelp_gateway20sp04/helpdata/en/10/2b9c8a863a451ebe6bd4358d9d6adb/frameset.htm .
