ERP facilitates the decision making but does not decide.
ERP provides comprehensive information to optimize but does not
optimize dynamically.
It automates and integrates transactions but does not target the

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.
ERP / SAP Overview |
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.

Those SAP R/3 software components that

form the Presentation Layer.
In 1990s SAP R/3 was released.
With SAP R/3, SAP ushers in a new generation of enterprise software
-- from mainframe computing (client-server architecture) to the
three-tier architecture of database, application, and user
interface.

With the Internet, the user becomes the focus of software
applications. SAP develops mySAP
Workplace and paves the way for the idea of an enterprise portal
and role-specific access to
information.
As mentioned earlier, with the introduction of mySAP Business
Suite, SAP is now organized
into a service-based architecture, which has the following:
mySAP Customer Relationship Management (CRM)
mySAP ERP
mySAP Product Lifecycle Management (PLM)
mySAP Supply Chain Management (SCM)
mySAP Supplier Relationship Management (SRM)
mySAP ERP addresses the core business software requirements of the
most demanding midsize and large organizations -- in all industries
and sectors.
mySAP ERP includes four individual solutions that support key areas
of Enterprise Resource Planning:
mySAP ERP Human Capital Management (HCM) -- Maximize workforce
potential.
mySAP ERP Financials -- Turn finance into a strategic business
partner.
mySAP ERP Operations -- Free up resources; budget for
innovation.
mySAP ERP Corporate Services -- Streamline business processes and

Content of enhancement packages
From a functional view each SAP enhancement package contains
several “Business Functions”.
From a technical view each SAP enhancement package contains new
versions of existing software components, grouped by a “technical

If installed:
No UI or process change until a business function is activated via

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.

ERP / SAP Overview |
ABAP programs are objects of the R/3 Repository. Like all other
Repository objects, you maintain them using an ABAP Workbench
Tool.
To open ABAP programs directly from the tool ABAP Editor, select
the menu path Tools -> ABAP Workbench ->Development ->
User Interface -> ABAP Editor from the SAP menu of SAP Easy
Access (or start Transaction SE38). If you want to change a program
using this method, you must already know its name and
environment.
This procedure is only suited for maintaining or creating
relatively simple or short programs, which have few or no
additional components. It is better to access ABAP programs through
Tools -> ABAP Workbench -> Overview -> Object Navigator
from the SAP menu of SAP Easy Access (or start Transaction
SE80).
