SAP R/3 stands for Systems Application for Products in data processing Real-time 3-tier architecture.

Non ERP
 client-server technologies
 Ex: Oracle/VB

ABAP stands for Advanced Business Application Programming.

Front end for SAP R/3 is SAP-GUI.

In SAP R/3 we have
 17,000 pre-defined tables (default)
 13,000 pre-defined applications

ABAP Methodologies:

1. ABAP Transactions  for modifying pre-defined applications (2%)
2. BDC (Batch data conversion)  Data transferring from non-SAP to SAP (20%)
3. SAP Scripts  works with respective business process (8%)
4. ABAP Reports  to design reports for SAP R/3 environment (70%)

Cross Applications:




RFC (Remote Function Call):

Provides integration between distributed environments.


BAPI (Business Applications Programming Interfaces):

Provides an interface between R/3 with third party front-end.
Ex: SAP R/3 VB

SAP R/21990 SAP R/3  1992 mySAP.com SAP min & SMB IS


• SAP R/2  1990 (mainframes) –ABAP language
• SAP R/3  1992 (RDBMS) – ABAP language(designed based on ‘C’ language)
- Major advantages: It is database independent
It is platform independent
• mySAP.com – for e-business solutions
- it is comfortable for small and medium scale industries
- where as SAP R/3 is very expensive for top MNC’s
• SAP MIN or SMB (Small scale Medium scale Business)
- this technology is very cheaper when compared to SAP R/3
- it is used for particular department for ex: Sales department
• IS(Industry Specific) – it maintains database specific industry
- where as SAP R/3 maintains generalized database


New Dimensional Technologies:

• BIW or BW(Business Information Warehousing)
→ Uses data warehousing technology
• APO(Advanced Planner & Optimizer)
→ Uses supply chain management technology
→ better than ERP products
• SAPCRM(Customer Relationship Management)
• SEM(Strategy enterprise manager)
• SRM(Strategy Relationship Manager)
• SAP Portals
→ Used for e-business


Life Cycle Implementation / Post Implementation:

→ If x-company goes for R/3 technology then firstly steering committee will be created.
EPC(Enterprise Process Control) – VISIO & ABIS tools for preparing EPC diagram.

→ flow charts on ERP

→ with EPC project manager explains steering committee how the process goes on

Defining an R/3 System

The simplest definition of an R/3 system is "one database." In one R/3 system, there is only one database. To expand the definition, R/3 is considered to be all of the components attached to that one database. One R/3 system is composed of one database server accessing a single database, one or more application servers, and one or more presentation servers. By definition, it is all of the components attached to one database.

If you have one database, you have one system.During an implementation, there is usually one system (or one database) assigned to development, one or more systems designated for testing, and one assigned to production.

The term R/3 system landscape denotes a description of the number of systems within an SAP installation and how they are designated, such as development, test, or production.

SAP stands for System Application and Product for data processing. In German language it stands for "Systeme, Anwendungen und Produkte in der Datenverarbeitung".

What is SAP?

SAP, started in 1972 by five former IBM employees in Mannheim, Germany, states that it is the world's largest inter-enterprise software company and the world's fourth-largest independent software supplier

The original SAP idea was to provide customers with the ability to interact with a common corporate database for a comprehensive range of applications. Gradually, the applications have been assembled and today many corporations, including IBM and Microsoft, are using SAP products to run their own businesses.

SAP is the largest Enterprise Resource Planning (ERP) solution software provider. Sap’s products focus on ERP, which it helped to pioneer. The company's main product is SAP R/3;the "R" stands for real time data processing and the number 3 relates to a three-tier application architecture: database, application server and client SAPgui.It provide the capability to manage financial, asset, and cost accounting, production operations and materials, personnel, plants, and archived documents ,Other major product offerings include Advanced Planner and Optimizer (APO),Business Information Warehouse(BW),Customer Relationship Management(CRM),Supplier Relationship Management(SRM), Human Resource Management Systems(HRMS),Product Lifecycle Management(PLM), Exchange Infrastructure(XI) and Knowledge Warehouse(KW).
