Sap Tutorial

Are you struggling to find out the best source to learn the SAP ERP technology? I think you are at the right place to learn and explore the knowledge in the SAP ERP module. SAP is one of the topmost Enterprise resource planning modules you can see in today’s market. Today we are going to discuss the best ERP module that is SAP. This SAP tutorial is designed to provide you a basic understanding of one of the bestselling enterprise resource planning or ERP packages in the world, popularly known as SAP R/3 (generation 3 product). HKR’s SAP tutorial will for those who want to learn how to develop world-class business applications and also implementation knowledge in functional modules. What you are waiting for; let’s get started,

SAP revolution:

In the year 1972, five German entrepreneurs namely Dietmar Hopp, Hans – Werner Hector, Claus Wellenreuther, Klaus Tschira, and Hasso Plattner had discovered this SAP company to increase the business potential. They named it SAP Systemanalyse und program Entwicklung (“System analysis and program development”).

SAP R/2 era: (1981 -1990)

Real-time business application touches more of the business-related applications: SAP R/2, it’s a fully packaged mainframe software application processes and integrates all the enterprise business functional applications. The growing power of mainframe servers is enabling SAP to expand its customer base to approximately 200 companies.

SAP R/3 era: (1991-2000)

Here the SAP real-time application reaches the Desktop: this is a client-server version of the standard application software that allows a large number of businesses to run more efficiently across the globe. SAP’s revenue and employee number continue their rapid ascent reaching DM 707.1 million and nearly 2,700 members respectively. The company now has more than 14 international subsidiaries and more than 2,500 customers in 32 different countries using its ERP software.

SAP Era: (2001 – 2010)

These SAP real-time moves to the web development applications, cloud computing, mobile developments, and in-memory computing open up the new version for real-time data access- anywhere, anytime. SAP expands mySAP.COM, making it a comprehensive technology for business applications. As a result, SAP has the architecture it needs to help many larger companies integrate a wide variety of information technology systems.

SAP Era: (2011-Present)

SAP launches the new module known as SAP S/4 HANA and SAP C/4 HANA, 4th generation enterprise software to help customers become business intelligent enterprises. Customers, already more excited in 2010 by SAP’s in-memory computing, are able to take full advantage of its benefit in 2011. Initial customers implement the first-in memory application product, the SAP HANA platform, enabling them to analyze data in seconds rather than days or weeks. SAP’s strategy for mobile business applications is also bearing fruit since its acquisition of Sybase, an SAP company.

Now it’s time to know the definition of SAP:

What do you know about SAP?

SAP Architecture:

SAP R/3 is three-tier architecture and we will explain the important components.

SAP ArchitectureSAP R/3 is three-tier architecture and new generation enterprise software from mainframe computing technology (we can also call it client-server architecture). This three-tier architecture contains a database, application, and user interface servers.

Let me explain them one by one;

1. Presentation server:

Presentation server helps to create the system capable graphical interface.

  1. Presentation layer is also called a Client layer and this layer acts as user interactions.
  2. In SAP –ERP also supports user interaction purposes with the help of a Graphical user interface.
  3. Example for this type of server is Desktop, Laptops, and Mobile devices.

The below diagram will explain the process of the presentation server;

Presentation server


2. Application server:

The application server contains specialized system devices such as multiple CPUs and varieties of RAMs.

  1. Application layer also known as the Basic layer or Kernel layer.
  2. Almost all the SAP application programs are executed at the application layer level.
  3. Application layer also helps to establish the communication between the presentation and database layer.
  4. In the application layer, where the workload is distributed to the different work processes.

Application server

3. Database servers:

This database server contains specialized system applications with fast and larger hard-drives.

  1. Database server helps to store the data.
  2. Datastore can be of different types of data, they are business data, SAP tables, SAP programs, and SAP system data.
  3. Examples for database servers are Oracle, PeopleSoft, Microsoft SQL, IBM DB/2, Sybase, and Siebel.

Database servers

Client: A client is a logical portion of any SAP ERP R/3 database server. According to a business standpoint, a client can be defined as a logical group of various companies.

SAP Logon:

SAP Logon is used to generate any icons to logging into SAP R/3 systems. One important to be considered here is that usually SAP logons are not placed in the SAP R/3 windows group, instead, they are generated through the SAP logon menu. This type of SAP logon is available once you have installed the SAP GUI at your workstations.

SAP Logon icon:

SAP Logon icon

SAP logon Pads:

SAP logon Pads

Point to remember:

  2. Logon icons will log any user into one specific application server. A logon group will help the user to log onto one of several application servers that depends on the best performance system environment.

Adding a new SAP application server:

Steps:

To create a shortcut for connecting the new SAP application server, you should follow these steps:

  1. The First click on the SAP logon from the windows desktop -> then SAP logon pad will open -> then click on the “new” button as shown in the below screenshot:

Adding a new SAP application server

  1. Now click on the “next” button as shown below;

Adding a new SAP application server - 1

      3.Next step is to fill in this information:

  • Description: in this section, you have to provide meaningful short text details.
  • Application server: here provide the IP address details of the application server, which is provided by the basic administrator.
  • System number and System ID: this gives the system number details provided by the SAP basis administrator. Initially, it should be given as 00(by default).
  • SAP router string: provide the SAP router string information, which is given by the SAP basis administrator, sometime it is available in the left blank.

SAP router string information

SAP project life cycle

Stages of SAP project life cycle:

  1. Evaluation: this stage may be a decision that has to be chosen between different vendors or various product sections.
  2. Project preparation: this stage explains the SAP implementation and organization process details. The project preparation stage also provides complete knowledge of the business process.
