ABAP stands for Advanced Business Application Programming. It is a programming language used for building applications for SAP's ERP system.
Classical reports are simple reports that generate a list using basic ABAP commands. Interactive reports, on the other hand, allow the user to interact with the report and perform actions such as sorting, filtering or deleting data.
Transparent tables hold application data and can be accessed directly using SQL queries. Pooled tables are used to store data that is shared between different applications, while clustered tables store data from multiple transparent tables, which reduces the number of joins required to access that data.
An internal table is a data structure that can hold multiple rows and columns of data. They are used to store data retrieved from a database table or for intermediate calculations in a program.
An append structure provides a way to add fields to a standard SAP table without modifying the original structure. An include structure, on the other hand, is a structure that can be included in multiple other structures, making it easier to maintain and reuse code.
A function module is a self-contained unit of code that performs a specific task and can be called from multiple programs. A subroutine, on the other hand, is a piece of code that performs a specific task and is called from within a single program.
A BADI (Business Add-In) is a point within an SAP application where a custom-developed program can be called to modify the application's behavior. An enhancement point is a predefined point within an SAP program where custom code can be added to extend the program's functionality.
ALV (ABAP List Viewer) reports provide a more user-friendly interface to display data to end-users in a structured and interactive way. Classical reports generate a simple list that can be viewed in a basic GUI.
A Dynpro is short for Dynamic Program. It is a screen that is used to interact with the user in an SAP application. Components included in it are the screen layout, screen flow logic, and screen elements.
An implicit enhancement is a predefined point within an SAP program where custom code can be added. Explicit enhancements are defined by the programmer and are used to add functionality to specific areas of a program.
An ALV grid is a tool used to display data from an internal table in an interactive grid format. It provides features such as sorting, filtering, and editing data directly on the grid.
An ABAP/4 query is a tool used to create custom reports by selecting data from SAP database tables. It allows users to define their own selection criteria and grouping criteria.
GET parameters retrieve data from the user interface, while SET parameters set values in the user interface. SET parameters allow for data to be passed between different screens in an SAP application.
Smart Forms are a more advanced version of SAPscript, allowing for more flexibility and features such as dynamic tables and graphics. SAPscript is an older tool used for creating and printing forms in SAP systems.
There are three types of memory in SAP: ABAP memory, export memory, and shared memory. ABAP memory is used to store data for a single program, export memory is used to store data for multiple programs, and shared memory is used for data shared between processes.
A lock object is an SAP data structure used to control access to specific data in SAP systems. It prevents multiple users from changing the same data simultaneously.
IDOC (Intermediate Document) is a data format used to exchange information between different SAP systems or between SAP systems and external systems. It allows for a standardized way of communication and data exchange.
A BDC (Batch Data Communication) program is used to automate the process of data entry into an SAP system. It allows for the recording of a user's input and the automatic processing of multiple inputs in a batch format.
An RFC (Remote Function Call) is a mechanism used to call SAP functions from external systems or from within an SAP system. It allows for remote execution of functions in a different system, providing a way for data to be exchanged between systems.
The ABAP debugger is a tool used to find and fix errors in an SAP program. It allows developers to execute a program line-by-line and view the data in real-time, helping to identify any issues in the program logic or data.
If you are a professional developer and have been working with SAP ABAP or planning to switch your career path, there are a few things that you must consider to prepare yourself for the interview. As an SAP ABAP developer, it is essential to be familiar with the programming language, data structure, and other critical aspects of the software that you will be working with. This article lists some of the essential tips for preparing for your SAP ABAP developer interview.
Before heading to the interview, make sure that you have a thorough understanding of the SAP ABAP fundamentals. This includes the basics of SAP systems, data dictionary, programming, reporting, modularization, forms, and interfaces.
SAP ABAP is primarily an object-oriented programming language, and therefore, you must be familiar with different programming concepts, such as object classes, interfaces, inheritance, polymorphism, and abstract classes. Review these concepts and practice writing code, including debugging skills.
Be prepared to answer technical questions related to your experience and knowledge of SAP ABAP development. Make a list of potential questions and practice answering them ahead of time. This can help you to gain confidence and feel more comfortable during the interview.
Review your professional work experience and make sure that you are familiar with the different projects that you have worked on. Understand the details of the project, such as the technology used, the roles and responsibilities, and the outcomes achieved.
Good communication skills are vital when working in a team of developers. Make sure that you can clearly explain complex programming concepts and ideas to non-technical team members. Practice speaking in front of a mirror or with a friend to gain confidence.
In conclusion, preparing for an SAP ABAP developer interview requires a significant amount of time and effort. Recap your SAP ABAP fundamentals, review your coding skills, prepare to answer technical questions, review your work experience, and practice your communication skills. By following these tips, you can be better prepared for your SAP ABAP developer interview and increase your chance of landing the job.
Arriving late can give the impression of poor time management skills and a lack of respect for the interviewer's time. Always aim to arrive at least 15 minutes early to your interview.
