10 common SAP basis interview questions

Here are 10 common SAP Basis interview questions and their suggested answers:

1. How is SAP used in organisations?

This question tests your baseline understanding of SAP and how it's used in business. In your answer, try to include different use cases for SAP to demonstrate your range of knowledge.
Example: 'SAP retrieves and processes data from all business functions onto a single platform.

2. What are the responsibilities and duties of an SAP Basis administrator?

Employers may ask this question to determine what you understand about the position and what you think are its most important responsibilities. Besides naming the various day-to-day responsibilities of an SAP Basis administrator, you can consider briefly explaining why one or two of them are important in the role.
Example: 'SAP Basis administrators are generally responsible for managing the SAP environment. Some of their daily duties include configuring, monitoring and troubleshooting the operating environment. They may perform batch job creations, user administrations and authorisations and implement SAP kernel upgrades. More important responsibilities include checking the status of all work processes and background jobs or reviewing database performance. These are critical to ensure that the SAP system is functioning and there are no alerts or errors.'

3. What are SAP instances and why do we create them in the system?

The hiring manager may ask this question to determine if you know how to define an SAP instance, which can reveal your understanding of the relationship between resource allocation and work processes in the SAP system. When answering this question, you can give an example along with a brief explanation of that instance.
Example: 'An SAP instance is an administrative unit that groups together components of an SAP system. It's created when you instal and configure an SAP system. An instance can refer to memory, processors and other resources in the system. An SAP instance allows users to log in to the SAP system and share the same resources. Each and every instance has a certain number of work processes. SAP instances are defined by two-digit numbers between 00 to 99 and the system can contain more than one instance at a specific time.
For example, a dialog instance consists of hardware resources, dispatcher and work processes. Increasing the dialog instance can indirectly increase those components and allow more user logins at a time.'

4. Explain client administration in SAP and why we need multiple clients in the SAP system.

Interviewers may ask this question to assess your knowledge of user administration and how their structure affects security access and data exchange between different business units in the system. When answering this question, you can include some advantages of client administration, which can showcase your knowledge of SAP usage in larger organisations and companies.
Example: 'Users can create multiple clients on a single instance. Client administration provides data security as one user with one client cannot see the data of the other user with another client. SAP client can allow the sharing of the same resources between multiple users. This allows you to share the SAP system with a large number of users without requiring multiple instals of the software again.'

5. When creating a new user, what are the different user types in the SAP system?

This question allows interviewers to see if you understand the purpose of user administration, which is one of the basic duties of an SAP Basis administrator. In addition to listing the various user types, it's ideal to also include a brief explanation of what they are in your answer.
Example: 'There are five different user types. The dialog user is for interactive system access from GUI. The system user is for background processes and communication within a system while a communication user is for external RFC calls. A service user is for a larger and anonymous group of users. Reference users are non-person related users that allow for the assignment of additional authorisations.'

6. What is SAP NetWeaver?

Prospective employers may ask this question to check if you can articulate what one of the core components of the entire SAP software stack is. Answering this question accurately demonstrates you know how the SAP system operates, which is fundamental technical knowledge for a career in SAP Basis.
Example: 'SAP NetWeaver is an open technology software that's one of the central components of the entire SAP software stack. It provides the platform to run critical business applications like JAVA and ABAP and allows for integration between processes, people and information.'

7. What is transport management in SAP Basis?

Transport management is a crucial functionality in SAP Basis. It's important that you can explain what transport management is for and why it's essential in your answer.
Example: 'Transport Management System or TMS, is to define, configure and manage the system landscape in SAP environment. It can control new requests, monitor any changes, see which user implemented those changes and other vital information. Transport management is important because it can move, manage, control or copy development objects like programs, screens and customised settings through pre-defined transport routes and RFC connections within the system.'

8. What is RFC connection?

As one of the foundation communication protocols in SAP, it's essential that you can explain what an RFC connection is. You can consider mentioning some benefits of RFC connection in your answer, which can demonstrate your depth of knowledge.
Example: 'RFC connection is a remote function call and is the standard interface for communication between SAP systems. A trusted RFC connection between two systems allows for a trusted relationship to communicate and exchange information and data. RFC helps to reduce programming efforts as it allows them to avoid redeploying modules and methods at remote systems.'

9. What are the different categories for executing SAP background jobs?

A background job is a common process that runs behind normal interactive operations. Professionals frequently use it due to its automated properties that allows it to run seamlessly without user input. Answering this question can help employers understand if you know how to allocate and schedule background jobs in SAP.
Example: 'There are three categories. Class A is high or critical priority tasks that are urgent and critical, so it's necessary to schedule them with class A priority. Users decide how many background processes to assign to a class A priority job. Class B jobs are medium priority jobs that start executing after the completion of class A jobs. Similarly, class C are low priority jobs which only run once after the completion of class A and class B jobs.'

10. Can you instal SAP patches when other users are online or active?

Interviewers may ask this question to check if you know the appropriate time to perform system upgrades or patch installations as this is a key responsibility of an SAP Basis administrator.
Example: 'It's not possible to instal SAP patches if all other users are online. The support manager cannot update and this leads to the termination of installations. You can instal SAP patches only when there's an absence of users' login or active users in the SAP system.'
