SAP R/3 Communication Protocol

Communication among the three tiers server is
accomplished with the use of standard protocol
services,such as one provided by TCP/IP or CPIC
. TCP/IP ? Transmission Control Protocol
/Internet Protocol At the OS level TCP/IP
protocol used , Mainly to communicate with
database, application presentation layer CPIC
? Common Programming Interface Communication AT
the programming level ,R/3 system uses the CPIC
protocol for program to program communication and
also includes support for Remote Function Calls
(RFC).

INDUSTRY SOLUTIONs (ADD-ON s)

• Additionally,SAP actively develops special
  software packages on top of R/3 ,targeted to
  specialized vertical industries.These packages
  are known as INDUSTRY SOLUTIONs (IS) .These
  packages are fully integrated with the rest of
  R/3 applications.SAP has the following IS
  packages like
• IS-B Sap Industry solution for Banks
• IS-H Sap Industry solution for Hospitals
• IS-IS Sap Industry solution for
  Insurance,Money,Foreign Exchange
• IS-OIL Sap Industry solution for Oil companies

  Sector
• These IS-Packages are a collection of specific
  business processes,set of transactions,programs,sc
  reens,documentation's Which fully integrated with
  the R/3 applications.
• Other solutions like CRM , SCM , BIW ,
  PUBLIC-SECTOR etc. can integrate With the sap
  system .

15
Basis Software

• R/3 BASIS Software is the set of programs
  tools which interfaces
• with the computer operating system ,database
  ,Application server
• and the presentation interfaces .
• Basis software mainly R/3 common Kernel or R/3
  Middle ware
• which is the nucleus of a system known as
  the SAP KERNEL .
• The main kernel directory in application server
  is
• \usr\sap\ltSIDgt\sys\exe\run

16
R/3 WORK PROCESS or SERVICES

• In SAP naming convention , a service is a process
  or a group of work
• process .Computing system i e running the
  particular Services known
• as a server or Application server .

Dispatcher processes

• The SAP dispatcher is the control program which
  manages
• the resources of the R/3 applications.
• The main tasks of the dispatcher are as follows
• Balanced assignment of the transaction load to
  the appropriate work process
• Buffer management in the main memory.
• Connection with the presentation level.
• Organization of the communication process.

20
Dialog work processes(1)

• Dialog Step
• A dialog step is a sap r/3 screen,which is
  represented by a dynamic
• program(dynpro) .A dynamic program consists
  of a screen and all the
• associated processing logic .
• When users are entered something on the
  screen press enter ,they are
• actually making one dialog step .
• The dialog work processes are in charge of
  interactive task of the R/3 System . A dialog
  process performs the dialog steps corresponding
  to the user interactive sessions.
• The SAP profile parameter that controls the
  number of interactive Dialog Work Process per
  instance is rdisp/wp_no_dia

21
Dialog work processes(2)
22
Update work Process
The update process is in charge of
executing database changes when requested by
dialog or background work Processes.
23
Enqueue work Process
The enqueue work process is in charge of
lock Management system. It allows multiple
application Services to synchronize the access to
the database and maintain data consistency.
24
Background work Process
The background work processes are in charge
of executing ABAP/4 programs submitted for
background execution. SAP background processing
automates routine tasks and helps in optimize
computing resources. Using background processing,
SAP System runs programs for you. Background
processing lets you move long-running or
resource-intensive program runs to times when the
system load is low. It also lets you delegate to
the system the task of running reports or
programs. Your dialog sessions are not tied up,
and reports that run in the background are not
subject to the dialog-step run-time limit that
applies to interactive sessions. The SAP
profile parameter that controls the number of
background work processes per instance is
rdisp/wp_no_btc
25
Message work Server
The message server is a service used by
the different Application servers to exchange
data and internal messages. The message
server routes the messages between application
servers.
26
Gateway work Server
The gateway server allows the communication betwee
n the R/3, R/2 and external applications. This
service is a CPIC handler which implements the
CPIC protocol for Communication. This is commonly
known as a gateway. The function of the SAP
gateway is to exchange larger Amounts of data
between application servers.
27
Spool work Process

• The spool work process is in charge of formatting
• the data for printing and passing it to the host
• spool system.
• The SAP profile parameter that controls the
• number of background work processes per
• instance is rdisp/wp_no_spo

28

Basis Terminology (1)
R/3 System A R/3 System consists of combination
of database server and the application servers
. SAP System Identification The SAP System
Identification, often referred to as the SAPSID,
or SID, is a unique three-character code that
identifies the R/3 System. SAP System
Identification codes used are DEV for the
development system, QAS for the quality assurance
system, and PRD for the production
system. Client A client is a legal and
organizational entity in the R/3 System whose
business management data is protected against
unlawful access. In addition, a client Has
its own set of user data Is a logical system
with separate master records Has its own set of
table data on common table . System Landscape The
landscape consists of all R/3 Systems (Instances)
involved in the implementation project and client
architectures that access (or share) a common
transport directory.

32
Basis Terminology (2)
Customizing Customizing is the process of
configuring the SAP R/3 System such that the R/3
functionality fits the companys needs. Database
Server This is where the database resides. Main
data stores in this server . Application
Server This is where R/3 application runs. On a 2
tiered system, this would be combined with
the database server. Instance An installation
of R/3 on a application server . GUI Graphical
User Interface. The SAPgui is the software on
users computer or local server that allows to
connect to one or more of the SAP environments.

33
Disk Space Requirements

• To configure a R/3 Release 4.X System, each
  database will require approximately 20
• GB of disk space.
• An application server will require approximately
  2 GB of disk space .
• A client with pure customizing data will require
  between 700 to 1500 MB.
• If the client also contains application data,
  such as a production system, the storage
• requirements can increase to several GB.
• The disk space requirements can also be affected
  by the
• Relational database management system (RDBMS)
  selected
• Number of clients in the system
• Number of master data records
• Number of transaction data records
• Amount of historical data retained

34
SAP R/3 Directory structure (1)
SCM
These sap directories created by sap
installation
DVEBMGS00

• The physical parent directory of the whole sap
  application is /usr/sap
• Transport directory is /usr/sap/trans
• SAP system parent directory ltsapsidgt , which is
  /usr/sap/SCM
• If more than one sap system will installed on the
  same machine then additional
• directory will be created under /usr/sap/.. ..

35
SAP R/3 Directory structure (2)

• Sap mount directory is /sapmnt useful for
  sharing the common files with all
• system belonging to the same group .
• Mainly /sapmnt/scm ? indicates the directory
  /usr/sap/scm
• Directory /sapmnt/scm/sys/exe/run it contains
  all sap runtime programs
• this directory also called sap kernel
  directory.Most of the program files in this
• directory are directly used by sap processes
• Directory /sapmnt/scm/sys/profile which contains
  sap profile files like
• startup-profile ,default-profile
  instance-profile.
• Directory /sapmnt/scm/sys/global which contains
  global or common data
• managed by the SAP application shared by
  all instances ,all types of logs.

36
R/3 Client

• When Sap installed it comes with 3 default
  clients with default
• users and default password.

Client User Default Password
000 SAP 06071992
000 DDIC 19920706
001 SAP 06071992

37
R/3 Data(1)

• An R/3 System is subdivided into clients .
• In R/3 most of Customer business data in sub
  groups divided by
• clients ,these type of data is client
  dependent data
• When the SAP objects are just accessed by only
  one client, we
• define them as client dependant data.
• Some data in R/3 which is shared by all client
  like R/3
• repository data.This type of data is client
  independent data.

38
R/3 Data(2)

• R/3 database can be divided into two logical
  components
• R/3 repository object
• R/3 customer data
• R/3 repository central part of this is ABAP
  dictionary i.e. programs,screens,
• reports provided by
  sap or created or modified by sap user .
• Customer data customer data consists of any
  kind of data entered into r/3
• by the customer in
  time of sap implementation or day to day
• business processing .
• Customizing data
• This data generated when r/3 is configured to
  meet the particular needs of the customer through
  customizing.Most customizing data is
  client-dependent some is independent .
• Application data
• Also known as business data ,which generated day
  by day business processing. Mainly master data ,
  transaction data .
• User master data
• Records of R/3 users password authorization

39
System strategies(1)

• In time of system setup the question we have to
  face
• How many R/3 systems will be needed ?
• What function will be performed by each R/3
  system in a
• system landscape ?
• How many clients will be needed by each R/3
  system ?
• What role will each client play in the system
  Landscape ?

• Three types of Environment needed for a system
  strategies
• Development environment (DEV)
• For development activities .
• Quality Assurance environment (QA)
• For extensive testing the developed or
  customized object .Mainly for
• integration testing purpose.
• Production environment (PRD)
• For actual company business transaction.

• Combination of all the system is called SYSTEM
  LANDSCAPE .
• Three types of system landscape are
• Single-system Landscape
• Two-system Landscape
• Three-system Landscape

40
System strategies(2)

• Single-system Landscape
• Development client , Testing client , Production
  Client on a same server .
• Advantages
• For this type of system , hardware cost
  administrative cost is lower .
• Disadvantages
• Changes to client-independent or repository
  objects will affect the whole
• environment .
• The performance of the system affect all clients
• Production data is a accessible from development
  testing environment
• Problems during the implementation of other
  applications , when some
• production is going on .
• Problems when modifying standard programs

Most of the disadvantages with a one-system
landscape are associated with client independent
changes, repository changes, upgrades , that
immediately impact the production environment.
These disadvantages are a much greater problem
once the R/3 System is in a productive state.
41
System strategies(3)

• Two-system Landscape
• For this case development QA testing done
  on same system .
• But production on different system .
• Advantages
• The production system (PRD) containing only the
  finalized production environment .
• After completing the preparation phase (test,
  verification, and release), the parameters and
  programs can be transported from the development
  system (DEV) to the production system (PRD) .
• (DEV client ? QA client ? PRD System).
• Minimal amount of hardware investment.
• Minimal system administration and change request
  management required
• Disadvantages
• Recommended only for projects with a limited
  amount of ongoing development
• No separate quality assurance system (QAS) for
  isolated testing

42
System strategies(4)

• Three -system Landscape
• In this case development ,QA , production
  take place on different system.
• The most recommended system in SAP .
• Advantages
• New development can start without affecting the
  production environment.
• QA system allows for integration testing of
  developments before promoted
• to production.
• Production data is secure, security will prevent
  access to sensitive data
• client settings will prevent the unauthorized
  changing of data .
• Production performance is not affected by other
  clients, there is only one
• production client .
• The general sandbox client (SAND) in the
  development system (DEV) makes it
• easier to become familiar with the new
  application functions and conduct
• suitability testing
• Client-independent customizing testing can occur
  without conflicts
• Disadvantages

43
Transport management system

• Within the R/3 System Landscape customizing
  development changes performed,
• in a development client ,has to transfer to
  QAS client PRD client .
• SAP R/3 enables user to record changes to a
  CHANGE REQUEST ,which is
• distributed to other client or other R/3
  system .
• When changes to either customizing or repository
  objects are made,the changed
• objects are recorded to a TASK in a Change
  Request corresponding to a specific
• user .
• After completion the development ,user release
  the Change Request transport
• to QAS PRD system .
• Transport Directory ? \usr\sap\trans

44
SAP consultants

• SAP consultants divide themselves into 3
  categories
• FUNCTIONAL consultant
• BASIS consultant
• ABAP programmers
• FUNCTIONAL consultant Experienced people in some
  business areas
• who
  knows how to customize those modules
• to meet
  the customers need.
• BASIS consultant Technical consultants who
  taken care installation
• sap
  administration , database administration.
• ABAP programmer Technical consultant who writes
  sap programs
• reports for
  any new requirements in sap by
• using ABAP/4
  programming language.
• Customizing Once customer buy one sap-kit,it
  contains all the modules
• with all the business
  processes.the next step is to customize
• to suit business needs
  practices.

Navigation Using Transaction Codes

• SAP provides a unique multi-character identifier
  for each system task. This shorthand
• name is called a transaction code which is a
  navigation alternative to using a menu
• path to get to a system task
• Transaction code may contain letters only, or a
  combination of letters and numbers.
• Used in conjunction with a prefix such as /n
  or /o .
• e.g . SPAM , SU01 .
• /n ends the current transaction and switches to
  the new one without saving any data
• in the current transaction .
• /o opens a new SAP session and accesses the new
  transaction without ending the
• current one (which will remain open in the
  background session)

Command field with transaction Code.
54
Transaction Code(1)

• Transaction is an operation that lets a user make
  changes to a database .
• In SAP transaction is a sequence of related
  steps ,are screens in which data
• is introduced causing the generation of other
  events.
• The final task of a transaction is to modify the
  information which ultimately
• goes into the database. The database is not
  updated until a transaction has
• finished.
• All the transactions in the R/3 system have an
  associated transaction code.
• All available transaction are held in table TSTC
  .To see the table data we can
• use the transaction codes SE16 / SE11 .
• We can create user defined transaction code by
  using SE93 .
• The Used transaction code by the user can be
  monitored using the transaction code STAT and
  STAD.
