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 BASIS Training | SAP BASIS System Monitoring

SAP BASIS is a collection of programs and tools that act as integration with database, Operating system, Communication protocols and business applications (such as FI, CO, MM, etc). Full form of BASIS is "Business Application Software Integrated solution".

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
• Number of print requests
• ABAP dump analysis
• Database performance monitor
• Database check
• Monitoring application users

Why Daily Basic Checks/System 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:

• The status of each application server
• 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

The following table shows important transaction codes for system monitoring and performance checks:

SAP BASIS Online Classes | Introduction to SAP ERP

SAP is the world leader in enterprise applications in terms of software and software-related service revenue. Based on market capitalization, it is the world’s third largest independent software manufacturer supporting all sizes of industries helping them to operate profitability, grow sustainably and stay ahead of the competition in the market.

What is ERP?

Enterprise Resource Planning (ERP) is software that is built to organizations belonging to different industrial sectors, regardless of their size and strength.

If you are new to SAP and want to take SAP BASIS training online course, join SAP Trainings Online.

The ERP package is designed to support and integrate almost every functional area of a business process such as procurement of goods and services, sale and distribution, finance, accountings, human resource, manufacturing, production planning (SAP PP), logistics & warehouse management.

Business process integration

Every business, regardless of the industry they belong to, require connected systems with efficient information flow from one business process to another. Business Process Integration (BPI) plays an important role in overcoming integrating challenges that allows organizations to connect systems internally and externally.

Business Process Integration (BPI) allows:

• Automation of business processes,
• Integration of systems and services,
• Secure sharing of data across numerous applications, and
• Automation of management, operational, and supporting process.

The following illustration shows an overview of various business processes running in an enterprise and how they are integrated.

Evolution of ERP

During early phases of development, integrated solutions were designed for particular process areas such as:

Material Management − the integrated system was known as Material Requirement Planning (MRP)

Manufacturing − the integrated system was known as Manufacturing Resource Planning

However none of the integrated systems came with a complete solution for an organization covering major business process areas. In early 1990’s, the Gartner Group first used the acronym ERP. By mid–1990’s, ERP systems addressed all the core enterprise functions.

Functions of ERP

An ERP system typically performs the following functions:

• Supports the integrated business process inside the organization.
• Improves capital planning and helps in executing organizational plans and strategies.
• Helps speed up the decision-making process over the analysis of accurate data.
• Helps extend the business network to wider domains, expanding the products and services to reach more customers, suppliers, and partners.
• Identifies operational risks to improve governance.
• Provides protection against organizational data breaches and security threats to leakage of information.
• Makes the organization adaptable to the rapid changes in the business process according to the needs.
• Gives long-term profit by providing means to increase the customer base.

Functional areas

ERP is a business management software is usually a suite of integrated applications that a company can use to collect, store, manage, and interpret data from many functional areas including:

Financial Accounting − Deals with financial transactions and data.

Human Resource − Deals with information related to employee of an organization.

Customer Relationship Management − Deals with capturing and managing customer’s relationship, facilitating the use of customer experience to evaluate the knowledge database.

Sales and Distribution − Deals with order placement, delivery, shipment and invoicing.

Logistics and Warehouse Management − Deals with storage of products and shipment.

Manufacturing and Material Management − Deals with the production and production planning activities.

Supply Change Management − Deals with the movement of products, storing, managing, and controlling supplies.

Advantages of ERP

By integrating the business processes, the ERP offers the following advantages:

• Saves time and expenses.
• Allows faster decision-making by the management, utilizing the data and reporting tools designed in the systems.
• Single data source and sharing of data among all the units of an organization.
• Helps in tracking every transaction that takes place in an organization, from starting till end.
• Provides synchronized information transfer in between different functional areas such as sales, marketing, finance, manufacturing, human resource, logistics, etc.

Disadvantages of ERP

It is not always easy to incorporate ERP in an organization. ERP suffers from the following drawbacks:

• Sometimes business processes critical to an organization are to be re-engineered to align them with an ERP solution.
• Cost of complex integration can be very high.
• Switching from one ERP solution to another increases the implementation cost even further.
• End-users are to be trained for their daily operations.
• Customization is not preferred.

ERP Packages

Many companies develop and implement various ERP packages according to their budget and requirements to help them meet their business needs and run their business efficiently.

SAP BASIS Online Tutorial | Remote Function Call in SAP BASIS

What is RFC?

For business applications, it is necessary to communicate and exchange information (in pre-defined formats) with other systems. Hence, there are well defined mechanisms to enable this communication. SAP has also provided us with such mechanism called RFC, which stands for 'Remote Function Call'.

To communicate between SAP systems, there is a need to define a mechanism. One of the most common ways is to define Remote Function Call (RFC Connection) between two systems. By creating a trusted RFC connection between two systems, it allows you to create trusted-trusting relationship between systems wherein, you can communicate and exchange information and data.

There are different types of trusted RFC connections.

A calling interface for ABAP Programs (See SAP ABAP training for more info about ABAP)

A calling interface for Non-SAP programs.

Basis is a set of programs and tools that act as an interface with Database, Operating system, Communication protocols and business applications (such as FI, CO, MM, etc). Full form of BASIS is "Business Application Software Integrated solution". (Develop career with SAP BASIS training by experts).

Functions of the RFC interface:

Converting all parameter data to the representation needed in the remote system.

Calling the communication routines needed to talk to the remote system.

Handling communications errors, and notifying the caller, if desired (using EXCEPTIONS parameter of the CALL FUNCTION).

RFC is a SAP protocol to handle communications between systems to simplify the related programming. It is the process of calling a function module which is residing on a different machine from the caller program. RFCs can be used to call a different program on the same machine as well, but usually, it is used when 'calling' and 'called' function modules/ programs are running on separate machines.

Details about RFC

SAP Uses CPIC (Common Programming Interface for Communication) Protocol to transfer data between Systems. It is SAP Specific protocol. Remote Function Call (RFC) is a communications interface based on CPI-C, but with more functions and easier for application programmers to use.

RFC connections can always be used across the entire system. This means that an RFC connection you have defined in client 000 can also be used from client 100 (without any difference).

RFC is the protocol for calling special subroutines (function modules) over the network. Function modules are comparable with C functions or PASCAL procedures. They have a defined interface through which data, tables and return codes can be exchanged. Function modules are managed in the R/3 System in their own function library, called the Function Builder.

You maintain the parameters for RFC connections using transaction SM59. The R/3 System is also delivered with an RFC-SDK (Software Development Kit) that uses extensive C libraries to allow external programs to be connected to the R/3 System.

The only difference between a remote call of a function module to another server and a local call is a special parameter (destination) that specifies the target server on which the program is to be executed.

RFC Advantages

RFC helps to reduce the efforts of programmers, by letting them avoid the re-development of modules and methods at remote systems. It is capable enough to:

• Convert the data into the format understandable by the remote (target) system.
• Convert the data into the format understandable by the remote (target) system.
• Call up certain routines which are necessary to start communication with the remote system.
• Handle errors that might occur in the process of communication.

Types of RFC

Synchronous

Requires both the systems (client and server) to be available at the time of communication or data transfer. It is the most common type and is required when the result is required immediately after the execution of sRFC.

sRFC is a means of communication between systems where acknowledgments are required. The resources of the Source System wait on the target system and ensure that they deliver the message/data with ACKD. The Data is consistent and reliable for communication.

Used for

For communication between systems

For communication between SAP Web Application Server to SAP GUI

Asynchronous

It is communication between systems where acknowledgments are not required (it is similar to postcard delivery).It doesn't require both the systems to be available at the time of execution and the result is not immediately required to be sent back to the calling system.

The Source System resource does not wait for the target system as they deliver the message/data without waiting for any acknowledgment. It is not reliable for communication since data may be lost if the target system is not available.

Used for

For communication between systems

For parallel processing

Transactional

It is a special form of aRFC. Transactional RFC ensures transaction-like handling of processing steps that were originally autonomous. Transactional RFC is an asynchronous communication method that executes the called function module in the RFC server only once, even if the data is sent multiple times due to some network issue. The remote system need not be available at the time when the RFC client program is executing a tRFC. The tRFC component stores the called RFC function, together with the corresponding data, in the SAP database under a unique transaction ID (TID). tRFC is similar to aRFC as it does not wait at the target system (Similar to a registered post). If the system is not available, it will write the Data into aRFC Tables with a transaction ID (SM58) which is picked by the scheduler RSARFCSE (which runs for every 60 seconds).

SAP BASIS Tutorial | SAP BASIS Integration With ECC

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.

Introduction to BI/BW

SAP BI/BW is a data warehousing product and is based on SAP ABAP infrastructure. It is used to convert raw data into reports. This can also be used to build analytical reports and for decision making by business managers.

Using a Business Warehouse, you can combine data from different heterogeneous sources, organize and manage the data for detailed reporting.

This data warehousing product can easily be integrated with different SAP reporting tools. This product can help to analyze multidimensional data from different sources.

The key components in SAP NetWeaver Business Intelligence are:

• SAP NetWeaver Business Warehouse (see SAP BW training for details)
• SAP Business Explorer (SAP BEx) and
• SAP NetWeaver BW Accelerator (BWA)

Besides replicating data from the source to the SAP NetWeaver BW system, it is also possible to access the source data directly from the SAP NetWeaver BW system using Virtual Providers. The analytic engine provides methods and services for analysis, planning and generic services such as caching and security.

SAP Business Explorer BEx is used to define how data is displayed. This tool also supports the creation of Excel-based and web-based applications for analysis, planning, and reporting. The BEx applications created with the BEx tools can be integrated into the SAP Enterprise Portal. Integration with SAP Business Objects tools (Learn from SAP BO training by experts) offers further options for analysis and reporting in addition to the standard SAP BEx functions. You can access BI information (like reports, analysis and dashboards) with the SAP Business Objects BI Portal InfoView.

BASIS Integration With ECC

SAP ERP is based on SAP NetWeaver version. For example, SAP ERP 6.0 is based on SAP NetWeaver 7.0. SAP ERP is also based on enhancement packages; for example, ERP 6.0 is based on EHP04 and NetWeaver Enhancement Package — EHP01.

The software components always follow product numbering like SAP HR 6.04 belongs to Enhancement Package 4 for SAP ERP 6.0 and SAP BASIS 7.01 belongs to EHP01 for SAP NetWeaver 7.0.

Likewise,

SAP ECC 6.0 Enhancement Package 5 is based on SAP NetWeaver 7.0 Enhancement Package 02

ECC 6.0 Enhancement Package 4 is based on SAP NetWeaver 7.0 Enhancement Package 01

ECC 6.0 Enhancement Package 6 is based on SAP NetWeaver 7.0 Enhancement Package 03

Implementation of an EHP for ECC involves the application of SAP NetWeaver EHP (starting with ECC EHP 4).

SAP BASIS E-Learning | SAP Client Administration

Let us first understand what a client is before we move on to SAP client administration. A client is used in SAP system for multiple login on single instance. You can create multiple clients on a single instance. It also provides data security wherein, one user with one client can’t see the data of the other user with another client. In addition, there is no need to install the software for each and every user. SAP BASIS training by experts from SAP trainings Online makes you too become successful SAP consultant.

Client is defined as a self contained business entities or independent accountable business units in commercial, organizational and technical terms. One client is normally referring to one user of SAP system. Once customer maps to only one client at a time. One user with one client cannot able to see the data of another customer on the other client which provides isolated and security.

There is no need to install separate software’s for each user/customer.

Advantages of client concept:

Client concept comes in with the following advantages:

You can share the same resources between multiple users.

You can manage SAP system landscape as you can create multiple clients for DEV, QA and PROD team.

You can share your SAP system with a large number of users.

You can create clients in SAP system from 000-999.

SAP system comes with the following three standard clients:

000 Client − This is called master client and is available when you install R/3 system.

001 Client − This client is a copy of 000 client including the test company. This client is used to create new clients normally.

066 Client − This is called SAP Early watch and is used for diagnostic scans and monitoring service in SAP system.

Client contains

Application data: Data that are stored in the database tables.

Customizing data: Data created by customers when customizing their systems.

User master record: Defines the authorizations assigned to a user.

Data classification

Data in the database are classified as two types:

Client independent data/cross client data

Client dependent data

Based on these two types, clients have differentiation about the data accessing and displaying.

Client independent data/cross client data:

Data created on any client within the system

Data can be accessible from any client

Data is not specific to any client and it is belonging to all the clients

Ex: screen data, transaction data, repository data and dictionary data.

Client dependent data/Client specific data

Data created on the specific client and can be accessible through same client.

Ex: user data, authorization data, application data

Default Clients

SAP system comes up with three standard default clients.

000-Master client

001-copy of the master client

066-early watch client

000-Master Client

000 clients are available immediately after installing R/3 systems.

Client is called as master client

This client has client independent settings

This client contains test company’s simple organizational structure and includes all applications parameters, settings, configurations and transactions etc.

This client is normally used in business environment

001-copy of master client

Client 001 is called as copy of master client including the test company

Client 001 used to create new clients normally

Client 001 settings are client independent if they are customized or configured.

Client 001 can be customized to move it to the PROD environment

In general, users mostly use 001 client to create a new client

If the client 001 is customized, it won’t behave like master client.

066-early watch client

Client 066 is called as early watch client

Client 066 used to perform early watch service for customer systems

Early watch service is diagnosis and monitoring service for solution monitoring of SAP and non SAP systems.

Early watch service triggers alerts and the alert may contain performance issue, database administration related issues etc,
