Overview On Sap Netweaver Gateway

SAP NetWeaver Gateway is a technology that provides a simple style to connect devices, environments in addition to platforms to SAP software based on marketplace standards. The framework enables evolution of innovative people centric solutions bringing the power of SAP concern software into new experiences such equally social in addition to collaboration environments, mobile together with tablet devices as well as rich cyberspace applications.


SAP NetWeaver Gatewayは、市場標準に基づいてデバイス、環境、およびプラットフォームをSAPソフトウェアに接続するための簡単な方法を提供するテクノロジです。 このフレームワークは、SAPのビジネスソフトウェアの力をソーシャルおよびコラボレーション環境、モバイルおよびタブレットデバイス、リッチインターネットアプリケーションなどの新しいエクスペリエンスにもたらす革新的なピープルセントリックソリューションの開発を可能にします。

ane.i The software offers the next capabilities:

• OPEN – Any Device, Any Experience, Any Platform
• PEOPLE – Optimized for user interaction scenarios
• TIMELESS – Non disruptive, any SAP Business Suite version
• DEVELOPERS – Simple APIs, no SAP knowledge, whatsoever tool
• STANDARDS – Based on REST, ATOM/OData

i.ii SAP NetWeaver Gateway offers connectivity to SAP applications using any programming language or model without the ask for SAP cognition past leveraging REST services together with OData/ATOM protocols.

1.two SAP NetWeaver Gatewayは、RESTサービスとOData / ATOMプロトコルを活用することで、SAPの知識を必要とせずにあらゆるプログラミング言語またはモデルを使用してSAPアプリケーションへの接続を提供します。

i.ii.1 What is REST & OData?

REST: Representational State Transfer is a way of software architecture for distributed systems such equally the World Wide Web. REST has increasingly displaced other pattern models such every bit SOAP together with WSDL due to its simpler manner. REST uses the touchstone GET, PUT, POST & DELETE methods and other existing features of the HTTP protocol. Key goals of REST include Scalability of component interactions, Generality of interfaces, Independent deployment of components, Intermediary components to trim back latency, enforce safety in addition to encapsulate legacy systems.

OData: The Open Data Protocol  is an open spider web protocol for querying in addition to updating information. The protocol allows for a consumer to question a datasource over the HTTP protocol together with go the event dorsum in formats like Atom, JSON or manifestly XML, including pagination, ordering or filtering of the data.

1.iii Key Benefits of SAP NetWeaver Gateway

• REST-enables your SAP arrangement, thereby lowering the information consumption barrier to the betoken that no specialist noesis of an SAP organisation is required earlier SAP business organization information together with functionality tin live consumed.
• Hides the technical complexities of your SAP organization landscape behind a unmarried interface that is tardily-to-purpose together with not-proprietary.
• Makes your SAP business organisation information together with functionality accessible to any external device or arrangement that tin can:
• Communicate using the HTTP(S) protocol.
• Understand OData messages.
• Provides Service Provisioning tools that permit the quick REST-enablement of existing ABAP functionality.
• Provides plug-ins for good known IDEs such every bit Eclipse, Visual Studio 2010 together with XCode. 
• two.0 Accessing SAP Business Data using Open Source tools
  Consumption of information through the SAP NetWeaver Gateway interface requires goose egg more than than the ability to brand an HTTP(southward) request. It does non demand the role of any SAP proprietary software or protocols. Consumption of information through the SAP NetWeaver Gateway interface does not impose whatsoever requirement on the application developer to be able to write software in ABAP, or even to have whatsoever understanding of the internal workings of an SAP organization.
  Using the ordinarily available development tools such as Microsoft’sec .Net or Apple’s XCode, or Open Source languages such every bit Ruby or PHP, nosotros can easily create user interfaces for SAP business organisation information too functionality past consuming the OData messages coming out of an SAP NetWeaver Gateway server. In gild to brand the OData consumption procedure even easier, SAP delivers several versions of the Gateway Consumption Tool. This tool tin currently be used by either Visual Studio 2010 or XCode together with generates an OData proxy object. In add-on to this, it can also generate a basic application that wraps the generated proxy object.
  Microsoft’second OData protocol is based on the Atom Publishing Protocol which inward plough, is based on the Atom Syndication Format. SAP has used the measure extensibility features constitute inwards OData to render its own annotations. The combination of OData’second information format and the SAP Annotations brand SAP business information both self-describing and human readable. These ii factors lonely lower the barrier for consuming SAP business organisation information in addition to functionality to the signal that no specialist noesis of an SAP arrangement is required earlier such information can live incorporated into a useful business concern application running on about external device.
  
  
  iii.0 Focusing area of the SAP NetWeaver Gateway
  The whole focus of the SAP NetWeaver Gateway interface is the REST enablement of SAP business information in addition to functionality, thereby making it slowly for non-SAP applications to eat. These could live:
  • Any external business concern application. due east.chiliad. Microsoft Office applications via a .Net (or fifty-fifty VBA) interface
  • Desktop machines using Web-based applications running PHP or Java or Ruby, etc.
  • Native applications on mobile devices E.K. iPad/iPhone or an Android device or a Blackberry.
  • Embedded devices such every bit manufacturing robots or road planning software in Satellite Navigation systems.
  • Any other concern scenario you tin think of involving roughly programmable device that tin verbalise HTTP(south).
  The SAP NetWeaver Gateway interface can be used to render the SAP Business Data to whatsoever programmable device that can talk HTTP(southward). In providing this capability, it hides the complexities that be within your system landscape by making function of:
  
  
  Protocol Adaptation: OData becomes the entirely communication protocol needed for y'all to provide or consume SAP Business Data to or from your SAP systems.
  
  
  Service Adaptation: Different types and versions of SAP systems now appear equally a unmarried, integrated repository of business organisation information.
  four.0 Development Process
  SAP NetWeaver Gateway software is loaded with various Service Provisioning tools, which generates the necessary origin code to jump-showtime the evolution of your external business organization applications. These tools tin be used inwards conjunction with widely used Integrated Development Environments (IDEs) such as Eclipse, Visual Studio 2010 and XCode. Integrated evolution environment plugins are available for Visual Studio, xCode & Eclipse, so Developers necessitate no SAP Knowledge.
  SAP NetWeaver Gateway creates novel Gateway objects from existing BAPI, RFC & ABAP Dynpro screens. Tools are available like RFC generators, BOR generators in addition to Screen generators which generate novel Gateway objects from existing BAPIs, RFCs or Dynpros. We can besides construct custom Gateway object using Gateway Add-On which provides y'all alongside the OData Channel. This is a gear up of ABAP classes and interfaces that can live used to train your own Gateway Model Objects inside your backend SAP organization. These are then registered alongside your SAP NetWeaver Gateway organisation inwards social club to make them accessible to the outside world equally RESTful services.
  The steps inward development process can be easily understandable from the below image too table.
• five.0 Conclusion
  
  
  SAP NetWeaver Gateway is non designed to be a channel for the type of transactional applications used past Power Users, neither is it designed to supersede existing middleware similar SAP NetWeaver PI. In addition to this, SAP NetWeaver Gateway applications are non designed to target A2A or B2B scenarios. Instead, SAP NetWeaver Gateway is the door through which the volume consumption of SAP concern information in addition to functionality is made possible. The target audience for SAP NetWeaver Gateway applications is a group known equally Occasional Platform Users (OPU). These are people who take advert hoc access to SAP information together with functionality inward an easy-to-eat style.
