In this transaction, we have a treestructure that performs a set of transactions and also keeps a track of all the alerts thatwere captured during the operation of the system4

2.SAP BasisSAP Basis — Installation of SAP GUISAP GUI is a client tool which is used to access remote central server and runs on differentoperating systems like Microsoft Windows, UNIX, Mac, etc. This is used to manage andaccess SAP applications like SAP ECC and SAP Business Intelligence System.Advanced Features in SAP GUIThe following are the advanced features of SAP GUI:Blue Crystal designSAP Blue Crystal is a new visual design theme which succeeds Corbu. It provides aconsistent design that allows users to seamlessly experience SAP GUI and NWBC elements.It is the standard theme of Fiori applications and comes with a new color palette and iconswhich are better scalable.The background texture has a stroke pattern in white and light blue with a gradient layer.As it replaces Corbu with Blue Crystal, this integrates SAP GUI for Windows 7.40 andNWBC 5.0Complete icons redesign for Blue CrystalAll SAP GUI icons used by SAP applications have been redesigned and are now fitting theBlue Crystal Design. Additionally, they are much better scalable than before. The new setof icons is exclusive to Blue Crystal Design.New default color for Blue Crystal iconsWhen you use it with patch 2, the main color changes from blue to dark gray in order toharmonize the design with the Fiori Application design.Supported Available Versions for Different PlatformsThe following are the supported available versions for different platforms: SAP GUI for the Windows environment SAP GUI for the Java(TM) environment SAP GUI for HTML / Internet Transaction Server (ITS)SAP GUI has been released separately for Windows and Java support and the latest versionfor Windows and Java is 7.4.5

3.SAP Basis — SAP GUI SelectionSAP BasisAs mentioned, there are three different GUIs available and we can select the right versionbased on the requirement. The following scenario can help you find a suitable SAP GUI:When users are working rarely in the SAP systemSuppose most of the users fall in this category, then it is suggested to use SAP GUI forHTML format. This allows you to save effort and money for client deploymentWhen users are working mostly in the SAP systemIn a case such as this, SAP GUI for Windows or SAP GUI for Java is recommended.When users are ABAP developersFor ABAP developers, it is recommended that they use SAP GUI for WindowsWhen users use operating systems other than MicrosoftIt is recommended they use SAP GUI for Java and HTML or they can use the SAP GUI forWindows on a remote server.When users are integrating Dynpro transactions to the PortalIt is recommended they use SAP GUI for HTML. This allows you to integrate classic Dynprobased applications into the portal easily.SAP Instance and SIDA SAP instance is when you install and configure a SAP system. This instance defines agroup of resources — memory, processors and other resources in the system. This allowsusers 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 witha single instance with only one CCMS or you can configure a system with two or moreseparate instances in client/server environment.Configuring a SAP instanceYou need to follow these steps to configure a SAP instance:Step 1: You need to define separate directories for UNIX, AS/400, or Microsoft WindowsNT server on which the instance is to run.Step 2: You can use a shared file system.10

SAP BasisStep 3: For each instance, there are entries created in operating system configurationfiles (/etc/services, /etc/sapconfig ).Step 4: There are communication entries created in the host.Step 5: For each instance, start and system profiles are created.Step 6: For each instance, operating system users are installed.Creating an instance for one serverYou need to follow these steps to create an instance for one server:Step 1: To create an instance, you should first define the mode of operation.Step 2: To create an instance, go to CCMS Configuration or use Transaction code RZ04.Step 3: Go to instances/operation modes as shown in shown in the screenshots below.Step 4: To create a new instance, click on create new Instance — (F6) option as in thefollowing screenshot:11

SAP BasisStep 5: Enter the host name and click on current settings. When application server isalready running, the system will display the current settings for that instance.Step 6: If the application server is not running, you should use the input help to displaythe possible entries and fill the below values.Step 7: Enter the host name and choose current settings. If the application server isalready running, the system will display the current settings for that instance. However, ifthe application server is not yet running, you should use the input help to display thepossible entries and fill in the following fields:12

SAP BasisSAP System NumberThe SAP System Number is the number that is mentioned when the SAP System isinstalled.Start Profile: Profile NameInsert the name of the start profile from Profiles to start the instance. You can also clickon “choose the input help” to display a list of available start profiles. You can select aprofile from the available list.Instance Profile: Profile NameYou have to select the name of instance profile from Profiles to run the instance. You canclick on “input help” to display a list of available instance profiles.To save the instance, click on Save button at the top ContinueMaintaining Instance DefinitionWhen you define operation modes, you need to maintain instance definition. Follow thesesteps to change the definition:Step 1: Use Transaction Code: RZ04Step 2: Select Instances/operation modeStep 3: Select an entry from the list of productive instances.Step 4: You can then change the data for that instance.Step 5: You can also delete an instance, operation mode using the same transaction code.Step 6: To delete an operation mode — From the list of productive operation modes,position the cursor on a line with the operation mode. Select operation mode Delete.This deletes the operation mode, and all the instances and work process definitionsassigned to it.13

4.SAP BasisSAP Basis — System Landscape & ArchitectureSAP system landscape is defined as an arrangement of SAP servers. Ideally, in a Sapenvironment, a three-system landscape exists. A system landscape consists ofDevelopment Server (Dev), Production Server (PROD), and Quality Assurance server(QAS).SAP Architecture is defined as a technology framework of SAP system and it changes withtime unlike the system landscape. SAP Architecture changes with new software like SAPECC 6.0, the most recent one.The following is a request in SAP System Landscape:DEVELOPMENT Quality PRODUCTIONThe following figure represents SAP three tier system landscape where work flows fromDev QAS PROD and not in backward direction.Let us now discuss the system landscape:Sandbox ServerWhen a project is implemented, at the initial stages, a sandbox server is used where allthe customization, configuration is performed.Development ServerNext is to save the configuration in development server and saved in workbench requestsand this has to be transported to Production server.Production Server14

SAP BasisYou can consider it as the final or the most refined stage where the work is done whenproject is in production/go live. All the changes that are required by the client areperformed in the DEV environment and later, the request is transported to production.SAP System 3 – Tier ArchitectureThe image given below shows 3-tier architecture of the SAP system. The presentationlayer 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 theprocessing and which is known as brains of an SAP system.An application server consists of multiple instances and communicates with the databaselayer of the three-tier architecture.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 securityreasons.The presentation layer consists of different components for ABAP and JAVA that enablesthe 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 distributeddispatchers in the ABAP system.15

SAP Basis 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 ABAPwork processes. Enqueue Server – This is used to handle logical locks set by the executed Javaapplication program. Java Dispatcher – This is responsible to receive the client requests viapresentation layer and forward to the server process. Gateway – This is used to manage communication between SAP system andexternal systems. ABAP Work processes – This separately executes dialog steps in R/3 applicationsseparately.16
