and written to the technical subsystem interface is error-free and complete.
TCP/IP can be used to establish a link through other computers using the Internet Protocol. The flow
of data can also be carried out using CPI-C.
Distributed Satellite Systems
The principle of establishing satellite systems that can operate locally and also integrate fully with a
central R/2 or R/3 system offers the following advantages:
The individual local systems can be implemented to best use the equipment and other resources
available.
The local system may be able to take advantage of low-cost computing power.
By using SAP standard interfaces, the satellites do not have to be SAP systems or R/3
applications; they can be legacy systems already fully operational and responsible for storing
specialized data.
The local system can run without continuous reference to the central host system, which is
thereby relieved of some workload that can be scheduled for more convenient times.
Applications as Satellites
Here are some applications that have successfully operated in the satellite manner:
DASS production control station
EIS-Executive Information System
Treasury Workstation
Components of the HR-Human Resources Management System
LVS-Warehouse Management System
The international operation of distributed applications is discussed in Chapter 9, "Building Global
Business Systems."
Reliability and Security
An R/3 implementation is in a critical role at the center of the management focus of your company.
The applications integrated with the R/3 system must be reliable and available to users. The functions
in all the applications must work correctly. The necessary data must be available when required.
In addition, the integrity of the data must be absolute.
