For SAP NetWeaver Mobile, we recommend a triple-environment system landscape:

  • Development Environment In this environment, you can develop mobile applications to meet your business needs.

  • Test Environment In this environment, you can test the design and runtime behavior of the developed mobile applications.

  • Production Environment In this environment, you can use mobile applications with the productive (real time) mobile clients.

The following figure shows the different systems in the three-environment landscape, and how they interact with each other.

This graphic is explained in the accompanying text.

The following table briefly describes the role of each system in the system landscape:

System

Role

SAP NetWeaver Application Server with Usage Type Mobile

A server that allows data exchange between the back-end system and mobile devices (laptops or handhelds). The server performs the following functions:

  • Stores data from back-end system

  • Deploys applications from Development Workstation to the Data Orchestration Engine (DOE)

  • Downloads or transports mobile applications to the client device

  • Synchronizes data between the client device and the back-end system

Mobile Device (Laptops or Handhelds)

A mobile device contains the mobile client along with the relevant mobile applications.

The client device allows the user to:

  • Work with the applications in the offline mode

  • Periodically connect to the DOE to synchronize data and applications

Admin Workstation

A system that can be used to store:

  • The setup packages when you are setting up devices

  • Data relevant for data carrier synchronization

Admin Client

Using this system, the administrator can logon and perform administrative tasks on the DOE. This system can also be a laptop to ensure that you can perform the required administrative tasks even if you are outside the office.

Development Workstation

The system on which you create and test mobile applications.

Back-end System

An existing SAP ERP system that contains all the data relevant for the business.

NWDI Server

An infrastructure that provides the development teams with a set of closely coupled central services to design, implement, build, deploy, and test applications. The main features of NWDI include:

  • Design Time Repository (DTR) to manage distributed development of software

  • Component Build Service (CBS) to manage the central build of the source code

  • Change Management Service (CMS) to manage the central administration of the Java development landscape

Portal Server

The system allows you integrate mobile-related information, and services on a browser-based user interface. It allows you to log on to the SAP NetWeaver Mobile Client using Single Sign-On (SSO).

The Portal Server:

  • Generates SAP Logon Tickets when you log on using your user ID and password

  • Stores programs that are required to start SAP NetWeaver Mobile client
