Overview of Ooabap Interview Process
The interview process for an ABAP position is an important step in the hiring process, as employers must be sure they are selecting the right person for the role. The process typically begins with an initial phone assessment, which is typically conducted by a recruiter or a member of the hiring team. This initial assessment can help employers gauge the applicant’s technical knowledge and experience level.
The second step in the process is usually a technical interview. This interview will usually consist of a deep dive into the applicant’s skills and experiences with ABAP. Questions may cover topics such as debugging ABAP code, implementing business processes and writing SAP user exits.
Once the technical interview is complete, the applicant may be asked to complete a practical exercise. This exercise may require the applicant to write a program or solve a problem using ABAP. This step is important for employers to determine whether or not the applicant has the required skills for the job.
The final step in the hiring process is often an in- depth interview with members of the team. This interview will provide an opportunity for the employer to get to know the applicant on a personal level, as well as delve deeper into the applicant’s skills and experience.
The ABAP interview process can be an intricate and arduous process, but it is important for employers to get the right person for the job. By taking the time to properly assess the applicant’s technical knowledge, as well as their interpersonal skills, employers can be sure they are making the right hire.

Top 15 OOABAP Interview Questions and Answers
1. What is SAP OOABAP?
SAP Object-Oriented ABAP (OOABAP) is a computer programming language used for the development of SAP applications that are based on the object-oriented programming paradigm. OOABAP is an extension of the original SAP ABAP (Advanced Business Application Programming) language, and is used for developing applications for SAP’s NetWeaver Application Server. OOABAP is a strongly-typed language and supports object-oriented concepts such as classes, interfaces, abstract classes, and inheritance.
2. What is the difference between Object Oriented Programming and Classical Programming?
Object-Oriented Programming (OOP) is a type of programming that focuses on creating objects that contain data and methods. It is based on the concept of objects, which can be thought of as entities that contain data and functions, or methods, that act on that data. OOP differs from classical programming in that it is based on an object-oriented model, rather than procedural programming. In OOP, the objects are the main focus of the program, while in classical programming, the focus is on the procedure or process of solving a problem.
3. What are the advantages of OOABAP?
OOABAP offers several advantages over traditional ABAP programming. It allows developers to easily create modular and reusable code. OOABAP also makes it easier to maintain and extend existing applications, by allowing developers to easily build on existing code. It also supports object-oriented concepts such as encapsulation, abstraction and inheritance, which allow developers to create more robust and maintainable applications.
4. What is an ABAP Class?
An ABAP class is a container for data and functions that are related to each other. It is an object-oriented programming language, which allows developers to create objects that have attributes and methods. An ABAP class contains a set of attributes (data) and methods (functions) that can be used to manipulate the data. The attributes and methods in the class are encapsulated, meaning they can only be accessed by the class itself.
5. What are the different visibility levels of an ABAP class method?
An ABAP class method can have one of four different visibility levels: Public, Protected, Private, or Package. Public methods can be called from outside the class, Protected methods can be called from other classes in the same package, Private methods can be called only by the class itself, and Package methods can be called from other classes in the same package.
6. What is the purpose of an ABAP Interface?
An ABAP interface is an abstract class that defines the public methods and properties of a set of related objects. An interface is used to define an object-oriented contract between an object and its consumers. It allows different objects to interact with each other without having to know the details of the implementation.
7. How is an ABAP Class Inheritance different from traditional inheritance?
In traditional inheritance, the parent class is responsible for providing the implementation of the inherited methods. In ABAP class inheritance, the parent class provides only the declaration of the methods. The implementation of the methods is provided by the child class. This allows the child class to modify or override the behavior of the inherited methods as needed.
8. What is the difference between an Instantiation and an Association?
Instantiation is the process of creating an object from an existing class. An association is a relationship between two objects. The association can be a one-to-one, one-to-many, or many-to-many relationship.
9. What is the difference between an Interface and an Abstract Class?
An interface is an abstract class that defines the public methods and properties of a set of related objects. An abstract class is a class with at least one abstract method. Abstract classes cannot be instantiated, but they can be inherited by other classes.
10. What is the purpose of the ABAP Event Handler?
The ABAP Event Handler is used to handle events that occur in an ABAP program. A program can define different event handlers for different types of events. The event handler is an object-oriented feature that allows developers to write robust, maintainable code.
11. What is an ABAP Method?
An ABAP method is a function or procedure that is defined in an ABAP class. It is used to manipulate the data in the class. Methods are defined with a visibility level, which determines who can access and use the method.
12. How are Exceptions handled in ABAP?
Exceptions in ABAP are handled using the TRY/CATCH block. The TRY block contains the statements that are to be executed and the CATCH block contains the statements that are to be executed when an exception is thrown. The exception is caught by the CATCH block and the appropriate error handling code is executed.
13. What is the purpose of the ABAP Debugger?
The ABAP Debugger is a tool used to debug ABAP programs. It allows developers to step through a program line by line and view the values of variables and objects. The debugger also allows developers to set breakpoints and watchpoints to observe the program’s behavior at certain points.
14. What is the difference between a Local Class and a Global Class?
A local class is a class that is defined in a program and can only be used in that program. A global class is a class that is defined in the global scope and can be used by any program in the system.
15. What is the purpose of the ABAP Dictionary?
The ABAP Dictionary is a tool used to define and manage the data structures used in an ABAP program. It allows developers to define the data types and relationships between objects. The dictionary also provides tools for creating and managing databases and tables.
