What is SAP and how it works?


SAP is the acronym for Systems, Applications, Products. For attaining better performance and data management in enterprises, SAP is one of the best providers of software solutions. When the SAP software was introduced in June 1972, only big organizations achieved their goals with this software.

But slowly, when it gained more popularity over the years, medium and small businesses also started running effectively well with SAP. And in the present corporate world, using SAP, organizations of all kinds are achieving their goals. As a result, SAP is the leading software for enterprise applications.

It is an innovative technology; it provides flexibility and security to administrative data and many more. Depending on the business module or design, SAP modules can be purchased by any entrepreneur.

Working procedure of the SAP software

Presentation tier 

The working process of SAP software starts with the presentation tier. It is located on the PCs of the business users and also provides the SAP GUI. SAP GUI (SAP graphical user interface) is a type of lightweight application installed on a computer that runs with MS Windows and Mac OS. The presentation tier provides a smooth interface for the communication purpose between the users and the SAP ERP system. Users can provide requests to the organization online or offline related to the batch job through the presentation system.

Application tier 

Like any other system with the central part, the application tier is the heart of the SAP ERP system. Application tires help execute the business logic, responsible for the transaction process of the clients, print jobs, run the report, coordinate access to the database, and interface with other applications used in the system.

With the application tier, an organization can distribute the application logic between several server machines when loads exceed the server’s processing power. The request which arrived from the presentation tier is now analyzed by the dispatcher of the organization of SAP central.

Database tier 

In the database tier, mainly the function of storage is accessed. And it can store two kinds of objects which are the business generated data and SAP application program. The company-generated data are the objects which the users create for processing various business means. Like sales orders or customer master records are the business-generated data.

The application program of SAP can be written in a routine that is ABAP (the unique programming language used in SAP), located in the application of SAP server for the database process during its runtime. In this, the data dispatched will pass the request to the message process.

SAP kernel 

The SAP system of Kernel is the collection of the executable programs and tools which are used in the process of business logic. The kernel process which starts or stops is called the SAP instances. The SAP ERP system contains the instances, which is the way to ensure that every instance is running at the dedicated server computer.

Every SAP has a dispatcher for processing numerous work processes. The dispatcher will distribute the task to the work process. SAP kernel has various techniques which are created during the runtime of multiple tasks. The process is D (dialogue), B (batch), V (update work), S (spool), and G (gateway work).

This is all about how the SAP software works. It can be a little tough to understand and follow in the organization, but the organization can fulfill various goals if adequately followed. You can also take some examples if this process seems more challenging. Let us consider an example as

There is a business user who runs the transaction called REPORT. This transaction will select one customer from the table of customers and can change the name. SAP ERP system will receive the input via GUI from the business user.

Then, the user will launch the transaction. Through this example, you can understand the principle of how SAP works effectively. But hiring the SAP experts for your organization will operate the SAP system properly.

But those candidates who don’t know anything about the SAP can go through the SAP Online Course at 3RI Technologies and get to know about it’s working and what it is, apart from being the leading software.
