SAP Mobile Infrastructure SAP BASIS

SAP Mobile Infrastructure (SAP MI) is a technology solution within SAP NetWeaver on which all SAP Mobile Business applications are or can be based. It is positioned within the People Integration, since the Mobile Infrastructure provides the basis for the Multichannel access to SAP and non-SAP solutions, applications, and information. With SAP MI it is also possible to develop mobile applications that are not SAP based. SAP MI is based on industry standards such as Java and XML, comes also with a Java virtual machine, and includes a development environment to design and develop mobile applications.

The SAP MI is installed locally on mobile devices and includes all the elements so that users can work remotely, that is, offline with the applications: a Web server, a database, and the application containing business logic. Additionally, the SAP MI includes the tools for synchronization and replication of the data, so that the mobile devices information is consistent with the back-end systems. The architecture of the SAP Mobile Infrastructure makes the platform open and independent of the mobile devices and the network and therefore includes supports for a full range of devices such as PDAs, tabletops, latptops, and advanced mobile phones. Supported connection types include the following:

  • Global System for Mobile Communications (GSM)
  • General Packet Radio Service (GPRS)
  • Universal Mobile Telecommunications Service (UMTS)
  • Local area network (LAN)
  • Wireless networks

Some of the SAP Mobile Solutions include the following:

  • SAP Mobile Asset Management (FI-AA)
  • SAP Mobile Service (as part SAP CRM)
  • SAP Mobile Sales (as part of SAP CRM)
  • SAP Mobile Procurement (for instance, vendor catalogs)
  • SAP Mobile Time & Travels (HR—travel expenses, time sheets)

The two main elements or components of the SAP Mobile Infrastructure include the following:

  • Client, represented by the SAP Mobile Infrastructure Client Component. The main elements of the client in a mobile device based on J2EE include
    • A local Web server to enable working with J2EE applications locally.
    • A browser as user interface.
    • Applications (JSPs, Servlets, ...).
    • Data persistence represented by a database, or JDBC.
    • APIs for data compacting and encryption (HTTPs), connections with the mobile device, application distribution, and information replication and synchronization.
    • The mobile client also has capabilities for application configuration, logging, and tracing.
  • Server, or SAP Mobile Infrastructure Server, includes a collection of components:
  • SAP MI J2EE Server Component
  • SAP MI ABAP Server Component
  • SAP Mobile Development Kit (MDK)

The server includes capabilities and tools for replication and data synchronization, guaranteeing that the information is not lost. It also guarantees the security and privacy of the information, error control, logical blocking of the information, and the consistency of the data against the back-end systems.
