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).

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\<SID>\sys\exe\run

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 .

Standard Work 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.

Dispatcher processes

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

Dialog work processes(1)

Dialog work processes(2)

Update work ProcessThe update process is in charge of executingdatabase changes when requested by dialog orbackground work Processes.

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.

Background work Process

The background work processes are in charge of

executing ABAP/4 programs submitted for

background execution.

The SAP profile parameter that controls the

number of background work processes per

instance is rdisp/wp_no_btc

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.

Gateway work Server

The gateway server allows the communication

between 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.

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

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.

Basis Terminology (2)Customizing

Customizing is the process of configuring the SAP R/3 System such that the R/3 functionality fits the company’s 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.

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

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/scmDirectory /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 processesDirectory /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.

Repository Object

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.

Some data in R/3 which is shared by all client like R/3

repository data.This type of data is client independent data.

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

System strategies(1)

Combination of all the system is called SYSTEM LANDSCAPE .

Three types of system landscape are

Single-system Landscape

Two-system Landscape

Three-system Landscape

• 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.

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

• If the system crashes the all three R/3 systems will be affected .

• If the system crashes the all three R/3 systems will be affected .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.

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

• Client-independent customizing activity must be carefully planned so that, it does not affect other customizing/development activities

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• Requires increased system administration and change management activities• Increase hardware cost

Transport management systemWithin 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 .

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.

ABAP/4 Advanced Business Application Programming (4GL)

ABAP/4 is a SAP programming language used in the development of all standard applications included with R/3 .SAP has designed a full purpose development environment known as ABAP/4 development workbench.

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)

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.
