2. Objectives • SAP AG • SAP R\3 Architecture • SAP R\3 Basics • SAP Modules

3. SAP • Systems, Applications, and Products in Data Processing (SAP) • Name of the company • SAP AG • SAP America • SAP America is a subsidiary of SAP AG • Name of the software • SAP R/2 – Mainframe version • SAP R/3 – Client/Server version

4. SAP AG • Founded in Germany (1972) • World’s fourth largest software provider • World’s largest provider of Integrated Business Solutions software

5. SAP R/3 • World-wide usage • Designed to satisfy the information needs for business sizes (small local to large all international) • Multi-lingual • Multi-currency • Designed to satisfy the information needs for all industries (industry solutions) • Hospital • Manufacturing • Chemical • Government

6. SAP R/3 • Enables a company to link it’s business processes • Ties together different business functions (integrated business solution) • Helps the organization run smoothly • Real-time environment

7. Architecture • Central relational database (e.g., Oracle, Microsoft SQL and many others) • Client/Server – (three-tiered) • ERP business modules(FI, MM, SD, CO, PP, HR) • Add-ons: • Customer Relationship Mgmt (CRM) • Supply Chain Mgmt (SCM) • Product Lifecycle Mgmt (PLM)

8. Relational Database • Tables: Defines and links thousands of tables of information • Advantages • Consistent and accurate data • Common definitions for terms • Shared, but restricted usage • Eliminates data redundancy SAP Overview

9. Client/Server Environment • Client • Software/hardware combination that can make a request for services from a central repository of resources • Server • Software/hardware combination that can provide services to a group of clients in a controlled environment

10. Client Process • The client is a process (program) that sends a message to a server process (program), requesting that the server perform a task (service). • Client programs usually manage the user-interface portion of the application, validate data entered by the user, dispatch requests to server programs, and sometimes execute business logic. • The client-based process is the front- end of the application that the user sees and interacts with. • The client process also manages the local resources that the user interacts with such as the monitor, keyboard, workstation CPU and peripherals.

11. Server Process • A server process (program) fulfills the client request by performing the task requested. • Server programs generally receive requests from client programs, execute database retrieval and updates, manage data integrity and dispatch responses to client requests. • Sometimes server programs execute common or complex business logic.

12. Application Server Application Server Database Server USER PCs USER PCs Application Server Application Server Three-tier Client/Server Architecture

13. Database and Application Server User PCs Two Tier Client/Server System

14. Basis System: Three-Tier Computer Hierarchy Central Database (Storage of all data) Access to Database: (Read / Write data) Database Input / Output of data to users Processing of data using application logic Application Presentation of the processed data to the user Presentation

15. PCs, Laptops, etc. Browser Client Network Internet Transaction Server Presentation Web Server Application Servers Application Database SAP Enterprise System

16. Three-Tier SAP Structure • In a three‑tier configuration, you use your own host for the three tiers. Using data from the database server, several different application servers can operate at the same time. • To ensure that the load on individual servers is as even as possible and to achieve optimal performance, you can use special application servers for individual application areas such as sales planning, distribution or financial accounting.

17. Three-Tier SAP Structure • To web‑enablethe SAP Applications, a Web Server and an ITS (Internet Transaction Server) are needed. • The web‑service and the services for the ITS can run on one server or on two dedicated servers. • The presentation in this configuration is provided by an Internet Browser. • The new SAP Web platform is NetWeaver.

18. SAP R/3 Basics

19. SAP R/3 Basics • Instance – each install of the SAP R/3 software on an individual application server • Configurable – each instance can be particularly configured to fit the needs and desires of the customer (within limits) • Most of the infrastructure decisions, including configuration decisions, occur during project implementation

20. Configuration • The process of tailoring SAP software by selecting specific functionality from a list of those supported by the software, very much like setting defaults (e.g., Word, Access) • DOES NOT involve changes to the underlying software code

21. Programming Code Modifications • Changes to the delivered code • ABAP/4 – Advanced Business Application Programming (ABAP) • If you change the code, SAP will no longer support you. • This should be done carefully as it can make migration to new versions of the software much more difficult

22. SAP R/3 Document Principle • Each business transaction that writes data to the database creates a uniquely numbered electronic document • Each document contains information such as • Responsible person • Date and time of the transaction • Commercial content • Once created, a document can not be deleted from the database

23. SAP Organizational elements and Modules
