What is SAP Basis and why it is important




SAP Basis is the technical foundation of the SAP system. It consists of various components that ensure the smooth functioning of the system. Some of these components are:


  • The database layer that stores all the data of the system



  • The operating system layer that provides the platform for running the system



  • The communication layer that enables the interaction between different parts of the system and external systems



  • The application layer that contains the business logic and processes of the system



  • The presentation layer that provides the user interface for accessing the system



SAP Basis is important because it supports all the activities related to system administration, such as installation, configuration, monitoring, troubleshooting, backup, recovery, security, performance tuning, etc. It also enables the integration of different modules and applications within the system and with other systems.


How to install SAP GUI (FrontEnd) and connect to an SAP system




SAP GUI (Graphical User Interface) is the software that allows you to access an SAP system from your computer. It provides a graphical interface for entering commands, viewing data, executing transactions, etc. To install SAP GUI, you need to download it from the SAP website or get it from your system administrator. You also need to have a valid user ID and password for accessing the SAP system.


To connect to an SAP system using SAP GUI, you need to follow these steps:


  • Launch SAP GUI from your computer.



  • Select or create a connection entry for the SAP system you want to connect to. You need to enter the following information:



  • The name or IP address of the server where the SAP system is running



  • The system number of the SAP instance you want to connect to



  • The client number of the client you want to log on to



  • The description of the connection entry (optional)



  • Click on Log On or press Enter.



  • Enter your user ID and password in the logon screen.



  • Select a language for your session (optional).



  • Click on OK or press Enter.



You are now connected to the SAP system and can start working with it.


What is an SAP instance and SID and how they are related to SAP architecture




An SAP instance is a group of processes that run on a server and provide services for an SAP system. An SAP instance can be either a dialog instance or a central instance. A dialog instance handles user requests from SAP GUI or other interfaces. A central instance handles additional tasks such as message processing, enqueue service, background processing, etc. An SAP system can have one central instance and multiple dialog instances running on different servers.


An SID (System ID) is a unique identifier for an SAP system. It consists of three alphanumeric characters that distinguish one system from another. For example, DEV for development system, QAS for quality assurance system, PRD for production system, etc. An SID is assigned to each SAP instance during installation.


SAP architecture is the way an SAP system is structured and organized. It consists of three layers: database layer, application layer and presentation layer. The database layer contains one or more databases that store all the data of the system. The application layer contains one or more instances that execute the business logic and processes of the system. The presentation layer contains one or more clients that provide the user interface for accessing the system.


What is a client and how to create, copy, delete and manage clients




A client is a logical unit within an SAP system that separates data and configuration settings for different purposes. For example, you can have different clients for development, testing, training and production within one system. Each client has its own master data, transaction data, customizing settings, user authorizations, etc.


To create a client in an SAP system, you need to use transaction code SCC4 (Client Administration). You need to enter a three-digit client number (such as 100) and a description (such as Development Client). You also need to specify some parameters such as currency, language, client role (test or production), etc.


To copy a client from one source client to another target client within one system or across different systems, you need to use transaction code SCC8 (Client Export) or SCC9 (Remote Client Copy). You need to select a profile that defines what data and settings will be copied (such as ALL for everything or CUST for customizing only). You also need to specify some options such as whether to overwrite existing data or not.


To delete a client from an SAP system


What are background jobs and how to monitor, delete and schedule them




Background jobs are tasks that run in the background of an SAP system without user interaction. They are used to perform operations that are not time-critical or that require a lot of resources. For example, you can use background jobs to run reports, send emails, update data, etc.


To monitor background jobs in an SAP system, you need to use transaction code SM37 (Job Overview). You can see the status, start time, end time, duration and spool requests of the jobs. You can also filter the jobs by various criteria such as job name, user name, date range, etc.


To delete background jobs in an SAP system, you need to use transaction code SM37 (Job Overview). You can select the jobs you want to delete and click on Delete. You can also delete multiple jobs at once by using a variant or a program.


To schedule background jobs in an SAP system, you need to use transaction code SM36 (Define Job). You need to enter a job name and a job class (A, B or C) that determines the priority of the job. You also need to specify the steps of the job, such as program name, variant name, print parameters, etc. You can also define the start condition of the job, such as immediate, periodic, event-based, etc.


What is transport management system and how to configure it and use transport requests




Transport management system (TMS) is a tool that allows you to manage the changes and customizations in an SAP system landscape. It enables you to transport objects such as programs, tables, views, etc. from one system to another. For example, you can transport objects from development system to quality assurance system and then to production system.


To configure TMS in an SAP system landscape, you need to use transaction code STMS (Transport Management System). You need to define the systems in the landscape and their roles (such as development, quality assurance or production). You also need to define the transport routes and layers that determine the sequence and direction of transports.


To use transport requests in an SAP system landscape, you need to use transaction code SE01 (Transport Organizer). You need to create a transport request that contains the objects you want to transport and a description of the changes. You also need to release the transport request when you are done with the changes. The transport request will then be moved to the target system according to the transport routes and layers.


What are patch administration and kernel updates and how to perform them




Patch administration is the process of applying patches or support packages to an SAP system to fix bugs, improve performance, add new features, etc. Patches or support packages are collections of corrections that are released by SAP periodically. They can be downloaded from the SAP Service Marketplace or obtained from your system administrator.


Kernel updates are the process of updating the kernel of an SAP system to a newer version. The kernel is the core component of the SAP system that contains the executable files and libraries that run the system. Kernel updates are also released by SAP periodically and can be downloaded from the SAP Service Marketplace or obtained from your system administrator.


To perform patch administration and kernel updates in an SAP system, you need to use transaction code SPAM (Support Package Manager) or SAINT (Add-On Installation Tool). You need to follow these steps:


  • Check the prerequisites for applying patches or kernel updates, such as system requirements, compatibility, backup, etc.



  • Download the patches or kernel updates from the SAP Service Marketplace or get them from your system administrator.



  • Upload the patches or kernel updates to your SAP system using transaction code SPAM or SAINT.



  • Apply the patches or kernel updates to your SAP system using transaction code SPAM or SAINT.



  • Monitor the progress and status of the patches or kernel updates using transaction code SPAM or SAINT.



  • Restart your SAP system if required.



What is RFC (Remote Function Call) and how to configure and test it




RFC (Remote Function Call) is a mechanism that allows you to call a function module in a remote system from a local system. It enables communication and data exchange between different SAP systems or between an SAP system and an external system. For example, you can use RFC to transfer data from one SAP system to another or to execute a report in another SAP system.


To configure RFC in an SAP system landscape, you need to use transaction code SM59 (RFC Destinations). You need to create an RFC destination that defines the connection parameters for the remote system, such as host name, system number, logon details, etc. You also need to specify the type of RFC destination, such as ABAP (for SAP systems), TCP/IP (for external systems), HTTP (for web services), etc.


To test RFC in an SAP system landscape, you need to use transaction code SM59 (RFC Destinations). You need to select an RFC destination and click on Test Connection or Remote Logon. You can also use transaction code SE37 (ABAP Function Modules) to test a specific function module in a remote system.
