SAP BASIS e-Learning | 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.

Free SAP BASIS Online Tutorials | SAP BASIS 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.

Online SAP BASIS Training: SAP BASIS | Selection of SAP GUI

SAP GUI is a client tool which is used to access remote central server and runs on different operating systems like Microsoft Windows, UNIX, Mac, etc. This is used to manage and access SAP applications like SAP ECC and SAP Business Intelligence System. Want to learn Basis by experts see SAP BASIS training for more details.

As mentioned, there are three different GUIs available and we can select the right version based on the requirement. The following scenario can help you find a suitable SAP GUI:

When users are working rarely in the SAP system: Suppose most of the users fall in this category, then it is suggested to use SAP GUI for HTML format. This allows you to save effort and money for client deployment.

When users are working mostly in the SAP system: In a case such as this, SAP GUI for Windows or SAP GUI for Java is recommended.

When users are ABAP developers: For ABAP developers, it is recommended that they use SAP GUI for Windows. SAP ABAP training by SAP Trainings online gives you the best practical methods teaching.

When users use operating systems other than Microsoft: It is recommended they use SAP GUI for Java and HTML or they can use the SAP GUI for Windows on a remote server.

When users are integrating Dynpro transactions to the portal: It is recommended they use SAP GUI for HTML. This allows you to integrate classic Dynpro-based applications into the portal easily.

SAP Instance and SID

A SAP instance is when you install and configure a SAP system. This instance defines a group of resources — memory, processors and other resources in the system. This allows users to login to the SAP system and share the same resources.

SAP instance is managed by CCMS. Users can login to the SAP system using an instance.

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.

Configuring a SAP Instance

You need to follow these steps to configure a SAP instance:

Step1: You need to define separate directories for UNIX, AS/400, or Microsoft Windows NT server on which the instance is to run.

Step2: You can use shared file system.

Step3: or each instance, there are entries created in operating system configuration files (/etc/services, /etc).

Step4: There are communication entries created in the host.

Step5: For each instance, start and system profiles are created.

Step6: For each instance, operating system users are installed.

Creating an instance for one server

You need to follow these steps to create an instance for one server:

Step1: To create an instance, you should first define the mode of operation.

Step2: To create an instance, go to CCMS > Configuration or use Transaction code RZ04.

Step3: Go to instances/operation modes as shown in shown in the screenshots below.

Step4: To create a new instance, click on create new Instance — (F6) option as in the following screenshot

Step5: Enter the host name and click on current settings. When application server is already running, the system will display the current settings for that instance.

Step6: If the application server is not running, you should use the input help to display the possible entries and fill the below values.

Step7: Enter the host name and choose current settings. If the application server is already running, the system will display the current settings for that instance. However, if the application server is not yet running, you should use the input help to display the possible entries and fill in the fields.

SAP System Number

The SAP System Number is the number that is mentioned when the SAP System is installed.

Start Profile: profile name

Insert the name of the start profile from Profiles to start the instance. You can also click on “choose the input help” to display a list of available start profiles. You can select a profile from the available list.

Instance profile: Profile name

You have to select the name of instance profile from Profiles to run the instance. You can click on “input help” to display a list of available instance profiles.
