SAP BASIS Online Learning | System Landscape and Architecture

SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system. Want to learn SAP BASIS by experts, see SAP BASIS training with experienced and real time implementation.

SAP system landscape is defined as an arrangement of SAP servers. Ideally, in a SAP environment, a three-system landscape exists. A system landscape consists of Development Server (Dev), Production Server (PROD), and Quality Assurance server (QAS).

SAP Architecture is defined as a technology framework of SAP system and it changes with time unlike the system landscape. SAP Architecture changes with new software like SAP ECC 6.0, the most recent one.

The following is a request in SAP System Landscape:

DEVELOPMENT >>>> Quality >>>> PRODUCTION

The following figure represents SAP three tier system landscape where work flows from Dev > QAS > PROD and not in backward direction.

Let us now discuss the system landscape:

Sandbox server: When a project is implemented, at the initial stages, a sandbox server is used where all the customization, configuration is performed.

Development server: Next is to save the configuration in development server and saved in workbench requests and this has to be transported to Production server.

Production server: You can consider it as the final or the most refined stage where the work is done when project is in production/go live. All the changes that are required by the client are performed in the DEV environment and later, the request is transported to production.

SAP System 3-Tier Architecture

The image given below shows 3-tier architecture of the SAP system. The presentation layer is the topmost one. This contains the device/application to control the SAP system. This can include mobile devices, end user systems or SAP GUI or web browser based client.

The presentation layer communicates with the application server to perform all the processing and which is known as brains of an SAP system.

The bottom layer is called the database layer. This is responsible to store all the data. The database of SAP system is kept on a separate server for performance and security reasons.

The presentation layer consists of different components for ABAP (see SAP ABAP training by experts to learn) and JAVA that enables the communication and processing of data in SAP system.

The key components of the presentation layer include the following:

Message Server − This is used to manage communication between distributed dispatchers in the ABAP system.

Message Server − This is used to manage server processes and JAVA dispatchers. It is used to manage communication within JRE.

Dispatcher Queue − This is used to store multiple work process types.

Dispatcher − This is used to distribute the requests to the work processes.

Memory Pipes − This is used to manage communication between ICM and ABAP work processes.

Enqueue Server − This is used to handle logical locks set by the executed Java application program. (Learn to program by Java training).

Java Dispatcher − This is responsible to receive the client requests via presentation layer and forward to the server process.

Gateway − This is used to manage communication between SAP system and external systems.

ABAP Work processes − This separately executes dialog steps in R/3 applications separately.

6.What is developer key? How to generate developer key?
The developer key is a combination of you installation number, your license key and the user name. You need this for each person that will make changes in the system.
7.Why do we create instances in SAP system? How are these instances configured?
SAP instance is defined when you install and configure a SAP system. These are used to refer to memory, processors and other resources in the system. SAP instance allows users to login to the SAP system and share the same resources.
A SAP instance is managed by CCMS and is used by users to login.
A SAP system can consist of one or more instances — you can set up a SAP system with a single instance with only one CCMS or you can configure a system with two or more separate instances in client/server environment.
We need to consider the following points to configure a SAP instance:

• You need to define separate directories for UNIX, AS/400 or Microsoft Windows NT server on which the instance is to be run.
• You can use a shared file system 
• For each instance, there are entries created in operating system configuration files.

8.In a situation where My SAP system is down (Users unable to login to SAP system), How to analyze the problem?

Support Package: SAP support packages is a bunch of corrections, this can be used by applying transaction SPAM.
12.What is OK code and Tcode?
“OK” code is used within a program to execute a function. “Tcode” is shortcut which helps to run a program.
13.How do you check the installed software components and product versions on SAP system?
Go to SAP system data → Click on component magnifying glass.
The following two options will be displayed

• Installed software component versions
• Installed component versions 

14.What is client Administration in SAP system? Why do we use multiple clients in SAP system?
A client is used in SAP system for multiple login on a single instance. You can create multiple clients on a single instance. It also provides data security as one user with one client can’t see the data of the other user with another client and also there is no need to install the software again.
The following are the advantages of client administration in SAP system
Using SAP clients, the sane resource can be shared between multiple users.
It helps you to manage SAP system landscape as you can create multiple clients for DEV, QA and PROD team.
It allows you to share the SAP system with a large number of users.
15.What are default clients in SAP system? How can you create a new client in SAP system?
SAP system comes with the following three standard clients
000 - This is called the master client and is available when you install R/3 system.
001 - This is a copy of 000 and it comes with a test company. Generally, this client is used to create new clients.
066 - This is called the SAP Early watch. This is used for diagnostic scans and monitoring service in the SAP system.
Following are the steps to create a new client in SAP

• To create a new client in SAP system, use transaction code SCC4.
• To create a new client, enter the following details after clicking on new entries:
• Client number and name
• City
• Currency, roles

Enter client specific data and set permission for the clients as per your requirement and click on save.

16.What is private mode? When does user switch to private mode?
Private mode is a mode where the heap data is getting exclusively allocated by the user and is no more shared across the system. This happens when your extended memory is exhausted.
17.Version or name of SAP that is implemented in real time? 
The version depends on implementing modules

SAP BASIS Tutorial | Support Package and Stack Upgrade: SAP SPS

What is a support package?

• When an end user of SAP finds a bug in the SAP product, he reports the same to SAP support. SAP programmers inspect the bug and develop a correction for the bug. This correction is known as SNOTE (SAP Note).
• With time, multiple end users, report bugs for which SAP releases SNOTE. SAP collects all these corrections in one place and this collection is called SUPPORT PACKAGE. This support package also includes enhancements to earlier versions of SAP.
• Support Packages are implemented in SAP system using Transaction SPAM (Support Package Manager)

Learn more about support packages from SAP BASIS training by industry leading experts by SAP Trainings Online.

What is support package stack (SPS)?

The support package stack is a list of ABAP and Java support packages for all software components (SC) included in SAP Netweaver (See SAP Netweaver training for more details). It is used to bring each Software Component of SAP NetWeaver to a defined Support Pack (SP) level.

Support Package Stack, commonly known as STACK bundles all required components or individual patches that are already tested together and recommended applying as SPS instead of individual patch (until and unless you face some problem which requires certain components to be patched).

What are support pack stack version numbers?

Support Package Stacks have a release number, and a Stack number, Example, SAP NetWeaver '04 Support Package Stack 11.

Each software component has a separate sequence of support packages:

The following list contains the technical names of a number of components and the notation for their support packages:

COP (Component Package)

SAP_APPL (SAP APPL Support Package): SAPKH<rel><no>

SAP_BASIS (Basis Support Package): SAPKB<rel><no>

SAP_ABA (Application Basis SP): SAPKA<rel><no>

SAP_HR (SAP HR Support Package): SAPKE<rel><no>

SAP_SCM (SCM Support Package): SAPKY<rel><no>

SAP_BW (BW Support Package): SAPKW<rel><no>

SAP_CRM (CRM Support Package): SAPKU<rel><no>

Pre-requisites for Support Package implementation

• Support packages should be always applied in client 000.
• The user to be used for the support package implementation must have authorizations equivalent to DDIC or SAP*
• Call the transaction SPAM and see if any previous Support Package import is incomplete. You can proceed ahead unless the previous support package import is successful.
• Ensure that there is enough space in the transport directory. The transport directory is located at /usr/sap/trans

Steps to upgrade the support package

Step1: Download support packs

Support packages are available in SAP support portal

Step2: Loading support packages

To load support packages we have two options:

From application server

From front end

From Application server

Download the support packages from service marketplace and save then at OS level in directory/usr/sap/trans

Uncompress these files using sapcar executable

Step 3: SPAM/SAINT Update:

• A SPAM or SAINT update contains updates and improvements to support package manager (SPAM) and addon installation tool (SAINT). There is always one spam update for each release. SPAM/SAINT update is mandatory before any support package upgrade.
• On the initial screen in Support Package Manager, choose Display/Define.
• A list of installed software components (for example, SAP_BASIS, SAP_HR, SAP BW training) is displayed.

Once you select the required component, the current queue appears. This queue contains the Support Packages available for the selected component in your system. If you want to define the queue for another software component, choose Other Component. If the displayed queue meets your requirements, you can confirm it by choosing Confirm Queue

Importing Queue

Once you a define a Queue (Step 4) while selecting a particular component (for which we want to upgrade support pack), we need to do 'Import queue' to start importing/applying that particular selected support pack (as per the standard SAP process).

Choose Support Package --> Import Queue

Conforming Queue

Confirm that the queue has been imported successfully into your system. This allows you to import Support Packages in the future. You will not be able to import Support Packages further, if you do not confirm the queue.

Once Queue has been imported, SPAM status becomes YELLOW

SAP BASIS Training | SAP BASIS User Activities

SAP BASIS
administrators control the access to applications by creating users, maintaining the same users. Users can be collected in groups according to the criteria in a company or a department and based on roles they perform in the project. A typical company will have several separate SAP systems running for production, development, testing and SAP BASIS training, and perhaps a high-availability system mirroring production on top of everything else. Admins will have to keep all of these systems updated, optimized and communicating with each other.

Roles can be defined to either users individually or to the user group. Roles define the user’s authorization levels to navigate or access the specific set of functions or crucial applications.

Authorizations are the key building blocks of SAP security system. How to secure SAP system can be learnt from SAP Security training by SAP Trainings Online with best experienced faculty.

Authorization is the known process of assigning designated values to fields present in authorization objects.

Access to all system functionality in SAP is achieved through a compound set of authorizations

If the users do not have the necessary authorizations to perform a certain action in the system, predefined message. You are not authorized is displayed on the status bar of the screen.

User administration includes creating, managing and controlling access to R/3 system, various R/3 user types and its data.

The SAP NW application server (Learn from SAP NetWeaver training) java includes the identity management application for administration of users, groups and roles.

User administration major tasks are:

• Creating user
• Locking or unlocking user
• Deleting user
• Approving or rejecting users

The below diagram explains how users are connected to the servers:

SAP user types:

There are 5 different types available in SAP system:

• Communication
• Dialog
• Reference
• Service
• System

Communication users

Users are not allowed / possible to logon using SAP GUI and cannot able to access the data through SAP GUI screens.

Users are allowed to change the password if expired using external link.

SAP system always checks for the password expiry, initial password and prompts when it requires to change depends on the logon method. Main use of the users is for external RFC calls

These users can access the SAP system data through front end or external applications.

Dialog users:

Users are allowed to logon using SAP GUI and able to access data through SAP GUI screens

System validates the password expiration initial password and multi logons

The user can change the password by their own using SAP GUI

These users are individual users and individual personalized system access allowed.

Reference users:

Users are not allowed to logon using SAP GUI and cannot able to access the data through SAP GUI screens.

System doesn’t check for initial password and password expiration.

Users for general, non person related which allows the assignment of additional authorizations to the users like internet users.

These users used to give authorization to other users.

Service users:

Users are allowed to logon using SAP GUI and can able to access the data through SAP GUI screens

System doesn’t check for initial password and password expiration.

Multiple logins are allowed for this kind of users

Users are not allowed to change the password and only administrator can change the password.

These users have very restricted authorizations

These types of users are created for anonymous users.

After an individual authentication, an anonymous session begin with service user can be continued as a person related session with a dialog user.

System users:

Users are not allowed to logon using SAP GUI and can able to access the data through SAP GUI screens.

System doesn’t check for initial password and password expiration.

Users are related system related and internal system processes.

The password change requirement does not apply to these user’s passwords and it cannot be initial or expired.

Only user administrator can change the password and multiple logons are permissible.

These users are for background processing, external and internal RFC calls.

SAP applications such as FI, CO, SAP PP etc. can interact with each other across different Operating systems and Databases with the help of BASIS.

BASIS is SAP Application Server Technology and alias of NetWeaver (SAP Netweaver training by experts from SAP Trainings Online) is SAP Web Application Server.
After adding java stack (the applications which are developed in J2EE, BSP, JSP etc,) improved security standard for business process. Both ABAP and Java stack can be monitored from one platform. Definitive protocols such as HTTP, SMTP, XML, SOAP, SSO, SSL and Unicode format are promoted by Netweaver (representation of handling text).

What is System Monitoring?

System monitoring is a daily routine activity and this document provides a systematic step by step procedure for Server Monitoring. See SAP BASIS training for more detailed explanation by experts.  It gives an overview of technical aspects and concepts for proactive system monitoring. Few of them are:

• Checking application servers
• Monitoring system wide work processes
• Monitoring work processes for individual instances
• Monitoring lock entries
• CPU utilization
• Available space in database
• Monitoring update processes
• Monitoring system log
• Buffer statistics
• Monitoring batch jobs
• Spool request monitoring

Checking Application Servers (SM51)

This transaction is used to check all active application servers.

Monitoring work processes for individual instances SM50

Displays all running, waiting, stopped and PRIV processes related to a particular instance. Under this step we check all the processes; the process status should always be waiting or running. If any process is having a status other than waiting or running we need to check that particular process and report accordingly.

Monitoring system wide work processes (SM66)

By checking the work process load using the global work process overview, we can quickly investigate the potential cause of a system performance problem.

Monitor the work process load on all active instances across the system

Using the Global Work Process Overview screen, we can see at a glance:

• Reason why it is not running
• Whether it has been restarted
• The CPU and request run time
• The user who has logged on and the client that they logged onto
• The report that is running
