Technology and Landscape

The target platform for SAP MSA Handheld includes handheld devices running Windows Mobile 5.0/6.0. The devices should have at least 128 MB of RAM and 128 MB of ROM.

SAP MSA Handheld uses SAP NetWeaver Mobile 7.0, which is a mobile framework that allows you to create mobile offline applications that work without connection to your corporate local area network (LAN). It is available for Windows Mobile and Win32 (Windows XP and Vista) devices. A mobile application based on SAP NetWeaver Mobile consists of three parts: client, middleware, and back end.

Client: The Mobile client part is based on Java and therefore requires a Java Runtime Environment installation. On PDAs this is the NSIcom CrEme Java Virtual Machine 3.2.x., which is shipped by SAP.

Middleware: The SAP NetWeaver Mobile middleware is part of the SAP NetWeaver Application Server (SAP NetWeaver AS). It contains functionality for synchronizing data, deploying applications to mobile devices, and accessing the back-end system. It also contains tools for monitoring and administrating your mobile landscape.

Backend: The SAP MSA Handheld back end consists of function modules that the middleware calls. They deliver the data to the middleware server.
