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
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.
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

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

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

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
