  • 2. 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
  • 3. SAP Technical Overview The Software-Oriented View of R/3
  • 4. 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.
  • 5. SAP Technical Overview
  • 6. 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
  • 7. What happens when I send a request to SAP?
  • 8. SAP Technical Overview Application Server Presentation . . . Internet Application Database Communication SAPGUISAPGUI InternetOffice Work- process Work- process Work- process Dispatcher TCP/IP Remote SQL IPC Local Buffer for R/3 Data, DW-Objects, ABAP-Objects
  • 9. 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
  • 10. 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
  • 11. SAP Technical Overview Work Process • Responsible for executing R/3 application tasks Database Interface Task Handler ABAP/4 Processor Dialog Interpreter Work Process
  • 12. SAP Technical Overview Different Kind of Work Processes for different Tasks Dialog SAP DispatcherBatch Spool Update Enqueue S 12 9 6 3 11 1 7 5 8 4 210 B M G Message Gateway R/2 R/3 V E
  • 13. SAP Technical Overview Dialog Work Processes Dialog • 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
  • 14. 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 4 210 B
  • 15. 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
  • 16. 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
  • 17. 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
  • 18. 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
  • 19. 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
  • 20. 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
  • 21. 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

  • 27. SAP Technical Overview Business Framework Business Component BAPI ALE BAPI Business Component • Business Component - contains business functionality • BAPI - interface between the components • ALE - integration of components
  • 28. SAP Technical Overview Business API (BAPI) • Defined method of a business object • Standardized methods allow customers to integrate their software with R/3 • Object-oriented in nature • BAPIs from all development platforms that support the SAP Remote Function Call (RFC) protocol
  • 29. SAP Technical Overview Other Interfaces • Application Link Enabled (ALE) - Interface that links different SAP systems and external application systems – Transport special data structures known as IDOCS (Intermediate Documents) • Object Linking and Enabled (OLE) - enables desktop users to access SAP data from many OLE client programs
