Top SAP ABAP Interview Questions for Freshers

1. What is SAP ABAP?

Answer: SAP ABAP stands for Advanced Business Application Programming. SAP ABAP (Advanced Business Application Programming) is a high-level programming language created by the German software company SAP SE. ABAP is primarily used for developing and customizing applications within the SAP ecosystem, which includes enterprise resource planning (ERP) systems and other business software solutions. C++ is used to implement the ABAP kernel. A procedural and object-oriented programming model are both supported by the hybrid programming language ABAP.

2. What do you mean by data dictionary in SAP ABAP?

Answer: ABAP Data Dictionary, also known as DDIC, is a central repository in the SAP system where all the metadata related to the database objects are stored. The DDIC is used to manage and maintain the definitions of the database objects such as tables, views, structures, data elements, domains, and search helps. The ABAP Data Dictionary provides a graphical user interface (SE11) for developers to create, change, and maintain the database objects and also provides a set of APIs for programmatic access to the metadata stored in the DDIC. This allows for efficient and centralized management of the data structures and definitions in an SAP system.The DDIC also plays an important role in ensuring data consistency and integrity by enforcing referential integrity constraints and by providing support for data types and data domains. Additionally, the ABAP Data Dictionary provides tools for generating database-independent ABAP code, which helps to simplify database migrations and improve the portability of SAP applications.

3. What are the different SAP ABAP/4 editors?

Answer: There are two types of SAP ABAP/4 editor exists:

  • SE38: It enables you to create programmes, see reports online, and basically does all of the object development in the ABAP/4 editor.
  • SE80: In addition, it facilitates the development of programmes, classes, modules, function groups, packages, and BSP (Business Server Page) applications.

Multiple inheritance can be defined as a class can inherit multiple interfaces. Due to Inheritance interface provides a base for polymorphism because the method declared in the interface behaves differently in different classes. Like class Interface can be defined locally or globally in the ABAP programming language.

Web Dynpro provides a model-based approach to building user interfaces, making it easier to design and maintain web applications. Developers define the structure and behavior of the user interface using metadata and annotations, which are stored separately from the actual code.

10. What are events in SAP ABAP reports?

Answer: In SAP ABAP (Advanced Business Application Programming), events in reports refer to the different points in the execution of a report program where specific actions or operations can be triggered or performed.
