Recent business trends favoring ERP growth
Business Process Reengineering ( BPR )
Most large companies are attempting to cut in-house development costs, improve
customer service, and speed products to market by reorganizing their existing
business processes.
Software Pricing
Licensing and pricing of mainframe based packaged applications are tied to the size of
mainframe system on which the applications run, but now customers are now
demanding user-based licensing options and major corporate applications like SAP
provide this instead of the conventional platform-based pricing technique.
Recent business trends favoring ERP growth
Globalization
As businesses are becoming more global in scope, people are demanding packaged
corporate applications that are available in a variety of languages with support for
multiple currencies.
Integration
As more and more companies are going for BPR, there is increase in demand for
integrated solution e.g.. different applications sharing a common database and thus
enabling data definitions and business rules to be applied across an entire
organization with the facility of doing modifications at one location only.

What is Customization ?
Customization
The adaptation of application software to customer-specific needs is
accomplished in two ways :
Coding
Programming customer-specific code that replaces or complements
components of the application
Configuration
Rendering the application appropriate to a specific customer by specifying
data on which the application operates
ABAP Programming
SAP R/3 applications are written in the ABAP (Advanced Business
Application Programming) programming language, and run within the
application layer of the R/3 System.
ABAP programs communicate with the database management system of the
central relational database (RDBMS), and with the graphical user interface
(SAP GUI) at presentation level.
