SAP R/3 - Integration Model

The R/3 System is based on an economic model that covers the following application areas in the above diagram.

The high level of application integration ensures that all functions can be accessed directly throughout the system. When R/3 system is installed, the data is integrated using a common database, Oracle, in this case.

Processing business processes with the R/3 system is not restricted to individual application modules. All data and functions are closely connected to each other. This enables cross-application business processes to be carried out as smoothly as possible.

SAP R/3 - Client/ServerSoftware-oriented viewHardware-oriented view

In SAP terminology, a software component provides a service (software-oriented view). This type of component can consist of a process or a group of processes and is then called a server for that service.

Software components that use this service are called clients. At the same time, such clients can also be servers for specific services.

A server often means a computer (host) on which software components run that provide specific services (hardware-oriented view)

SAP R/3 - Three-Tier Computer Hierarchy

In the distributed R/3 system based on client/server methodology, the r/3 components are spread across a three-tier computer hierarchy.

The database server, that is, the processes representing the database service, is installed on a central computer. This computer also houses at least one other service, the R/3 update service, thus making it responsible for all changes to the database. Multiple application servers can be connected to the database server. The application servers perform the tasks of the application.

Multiple frontends (such as workstation, PCs), which users are working, connect to each application server. These individual frontends handle all presentation tasks.

System Navigation

The first step to better understanding the power of the tool in front of you is to learn how to navigate though it, use its features and build an environment where you can be the most effective.

SAP BasicsNavigation - Starting the SAPgui (PC client)

After your PC has been installed with the sapgui client, a new icon will be added to your Windows desktop. Double-clicking on it will start the SAPlogon pad program. This program allows you to access multiple SAP R/3 system through a single interface.

SAP BasicsNavigation - Logging into the R/3 System

When logging in, select the appropriate client, your user ID, password and working language. When moving from field to field, use your Tab key, pressing enter only when you have filled in the required fields.

Your User ID is linked to a series of Authorizations, giving you access to certain areas and the rights to perform certain activities.

SAP BasicsNavigation - Logging out of the R/3 SystemYou can also click on the X button to log out of the system

SAP BasicsNavigation - Parts of an R/3 WindowWindow menuEnter iconFunction buttonsCommand boxFunction buttonsFunction buttonsStatus barSystem info

Look to your screen as a workspace. Many useful shortcuts and menu paths are set up as buttons on the tool bar. These buttons will change from screen to screen as your menu options change.

In the lower right-hand corner of your screen, you will find located in the Status bar, the system name and system time.

The Status bar can also be set up as the place where all messages are displayed from FI document numbers to Error messages. Clicking on the message bar will frequently give you additional information. The status Bar can be turned off in the Customizing display options icon area.

SAP BasicsNavigation - Using Menu Paths

There are several ways to navigate through the SAP Landscape. Using Menu Paths, you can travel from the Main menu after Logging In all the way to Product Costing or anywhere else in the system.

SAP BasicsNavigation - Using Transaction CodesIf you know the Transaction Code for the place you want to go, just type /N and your Transaction code in the command box and press enter!

The Command box is used to navigate in SAP using Transaction codes. Transaction codes for various functions like Create a sales order or Change a Customer Master Record are found following the menu path System-> Status from any screen and locating the Transaction field approximately left center.

Using the prefix of /N before a transaction code, allows you to go directly to the next transaction. Using /O before a transaction code will create a new session and then go directly to the next transaction.

Note: If you are in the main menu , you do not have to key in any prefix before a transaction code.

SAP BasicsNavigation - Multiple SessionsMultiple Sessions enable you to:Perform multiple transactions or find key information while in a live sessionOpen a session at any time and from any screen in the system

Menu Path :System ->Create Session :saves the session you are in and creates an additional workspace. Using the ALT and TAB keys on your keyboard allows you to toggle between sessions. Dont forget to save your work when a session is completed.

System ->End Session :closes the session you are in until you reach the final open session. You will then receive a option to log off of SAP.
