SAP R/3 Architecture and Conceptual Area
SAP (Systems Applications Products for data processing) is an ERP
software. It was developed in Germany by the company named SAP.
SAP R/3 system is to provide a suite of tightly integrated, large scale
business applications. Following are the standard set of applications or
functional module in R/3 system:
- PP (Production Planning)
- SD (Sales and Distribution)
- MM (Material Management)
- FICO (Finance and Controlling)
- AM (Fixed Asset Management)
- PS (Project System)
- WF (Work Flow)
- IS (Industry Solution)
- HR (Human Resource)
- PM (Plant Maintenance)
- QM (Quality Management)
You can learn about the functional areas in details by reading the R/3
online reference. It contains tutorials and information for all the
functional areas.
System Architecture
There are three servers in SAP R/3 architecture.
Presentation server is actually a program named sapgui.exe. It is
usually installed on a client machine. User can interact with the system
with the help of this server. Application server is a set of executables
that collectively interpret the ABAP/4 programs. Database server is a
set of executables that accept database requests from the application
server.
In three-tier client/server architecture the presentation servers,
application servers and database severs all run on separate machines.
For large systems this is the most common configuration and is common in
production.
In two-tier client/server architecture, the presentation and application
severs are combined and the database server is separate. This
configuration is used in conjunction with other application server.
Conceptual Area
Following are the three conceptual areas in the R/3 system-
- The Application Area
- The Basis Area
- The Development Workbench
In the Application area, you initiate transactions for the functional
areas within R/3. In the Basis area, you can run transactions that
monitor the R/3 system itself. The Development workbench is used to
create and test ABAP/4 program.
