About SAP Basis SAP BASIS Component is a unique layer in the SAP architecture. The BASIS component acts as a bridge between the computing infrastructure i.e. operating system, database, network architecture and the various modules in SAP such as FICO, MM, SD, PP, PS, QM etc. Basis is a business application software integrated solution. Simply, Basis is the administration of the SAP system. SAP Basis administrator will take care of the administration of the various SAP products Like ECC, CRM, SRM, SCM, BI.PI, EP, Solman Etc

Learning Objectives:

SAP Technical Overview Learning Objectives What the Basis system is How does SAP handle a transaction request Differentiating between the various work processes Understanding the basic functions of the Basis Module

PowerPoint Presentation:

SAP Technical Overview The Software-Oriented View of R/3

PowerPoint Presentation:

SAP Technical Overview The SAP R/3 System Architecture Implications for Application Programming Separate presentation and application layers implies that when you run an application program that requires user interaction, control of the program is continually passed backwards and forwards between layers. When a screen is ready for user input, the presentation layer is active , and the application server is inactive with regard to that particular program. As a consequence, the program logic in an application program that occurs between two screens is known as a DIALOG STEP .

PowerPoint Presentation:

SAP Technical Overview

PowerPoint Presentation:

SAP Technical Overview Application Layer (cont.) Application Server R/3 programs run on application servers The APPLICATION SERVER communicate with the presentation components, the database, and also with each other, using a MESSAGE SERVER . Main components: Work Processes (Dialog, Update, Enqueue, Batch, Spool) Dispatcher Gateway Message Server The SAP R/3 System Architecture

What happens when I send a request to SAP?:

What happens when I send a request to SAP?

Application Server:

SAP Technical Overview Application Server Presentation . . . Internet Application Database Communication SAPGUI SAPGUI Internet Office Work- process Work- process Work- process Dispatcher TCP/IP Remote SQL IPC Local Buffer for R/3 Data, DW-Objects, ABAP-Objects

Dispatcher:

SAP Technical Overview Dispatcher Program which manages resources of the R/3 applications Receives requests from user and passes them to the corresponding work processes Only one dispatcher per application server

Dispatcher Tasks:

SAP Technical Overview Dispatcher Tasks Balances the workload between the processes Buffer management in main memory Connection with the presentation level Organization of the communication processes

Work Process:

SAP Technical Overview Work Process Responsible for executing R/3 application tasks Database Interface Task Handler ABAP/4 Processor Dialog Interpreter Work Process

Different Kind of Work Processes for different Tasks:

SAP Technical Overview Different Kind of Work Processes for different Tasks Dialog D SAP Dispatcher Batch Spool Update Enqueue S 12 9 6 3 11 1 7 5 8 4 2 10 B M G Message Gateway R/2 R/3 V E

Dialog Work Processes:

SAP Technical Overview Dialog Work Processes Dialog D Responsible for the interactive tasks of the R/3 system Dialog work processes execute only one dialog step at a time and are immediately freed for the next user request Constantly switching between users

Background Work Processes:

SAP Technical Overview Background Work Processes Responsible for executing ABAP programs submitted for background execution Batch jobs schedule the sequence of program execution Used for running long and time consuming programs Batch 12 9 6 3 11 1 7 5 8 4 2 10 B

Spool Work Processes:

SAP Technical Overview Spool Work Processes Responsible for formatting the data for printing and passing it to the host spool system Only one spool work process allowed per server Spool

Enqueue Work Processes:

SAP Technical Overview Enqueue Work Processes Responsible for the lock management system Synchronizes database access for the multiple application servers and work processes Only one enqueue process per R/3 system to ensure data integrity Enqueue E

Update Work Processes:

SAP Technical Overview Update Work Processes Responsible for making database changes requested by dialog and background processes For better performance, this process should be on the database server Update V

V1 vs. V2 Update Processes:

SAP Technical Overview V1 vs. V2 Update Processes Time-critical processes are inside V1 and less critical ones within V2 Error situations in V1 : changes rolled back and V2 components not executed V2 : only changes of V2 components rolled back Update V

Message Server:

SAP Technical Overview Message Server Used by different application servers to exchange data and internal messages Routes messages, such as update or batch job starts, between application servers One message server per system M Message

Gateway Server:

SAP Technical Overview Gateway Server Allows communication between R/3, R/2, and external applications Exchanges large amounts of information between application servers Gateway can reside on any of the connected systems G Gateway R/2 R/3

Work Processes:

SAP Technical Overview Work Processes Number of work processes can only be changed after restarting the system Should have at least two dialog work processes Need to have at least one V1 and V2 processes Number of spool processes cannot be changed
