If you're preparing for a job interview that demands SAP ABAP on HANA experience, you should be prepared to answer a variety of technical and practical questions about the software. In this blog, we'll go over some common SAP ABAP on HANA interview questions to help you prepare and demonstrate your knowledge of the platform.
SAP ABAP on HANA is a technology that combines SAP's application server and HANA's in-memory capabilities to provide unrivaled performance. As the demand for skilled workers grows, interview questions have become increasingly important. We'll talk about things like the HANA database, ABAP programming, modeling, and optimization. It is important to note that SAP ABAP on HANA interview questions may change over time as technology changes, so candidates must keep current in order to succeed in the employment market.
we have divided these interview Questions into a few parts:
Ans: SAP ABAP on HANA is a technology stack that combines SAP application server technology with the in-memory capabilities of HANA to produce high-performance applications.
Ans: SAP HANA is an in-memory database platform, whereas SAP ABAP is a programming language used inside the SAP ecosystem to construct applications.
Ans: The ABAP CDS view is an ABAP data model specification that provides a unified view of data from many tables. It aids in the design and implementation of efficient data models.
Ans: For database processes, AMDP methods are utilised, whereas CDS views are used for data modelling. ABAP constructions are CDS views, while AMDP methods are database constructs.

Ans: Using approaches such as code pushdown, SQLScript, and data modeling, you can improve the speed of SAP ABAP on HANA applications.
Ans: The technique of code pushdown is used to move as much code as possible from the application layer to the database layer. It aids in boosting application performance and lowering the stress on the application server.
Ans: SAP HANA modelling is the process of developing a data model in SAP HANA through the use of various approaches such as graphical modelling, SQL scripting, and CDS views.
Ans: CDS views are essential in SAP ABAP on HANA because they provide a unified view of data from different tables, aid in effective data modelling, and increase application performance.
Ans: SQLScript is a programming language used in SAP HANA to create database procedures. It includes capabilities such as loops, conditionals, and variables that can be used to create complicated queries.
Ans: SAP ABAP on HANA may communicate with external systems via a variety of methods such as Remote Function Call (RFC), web services, and OData services.
Ans: Inner join returns only the rows that match between two tables, whereas left outer join returns all rows from the left table as well as matching rows from the right table.
Ans: Exception management techniques like try-catch blocks, message handling, and logging can be used to handle failures with SAP ABAP on HANA.
Ans: Indexing is critical in SAP ABAP on HANA because it improves application performance by allowing faster access to data.
Ans: Partitioning is a method of dividing a large table into smaller, more manageable segments. It improves application performance by minimizing the quantity of data that needs to be searched.
Ans: Views in SAP ABAP on HANA are classified as database views, CDS views, analytical views, and calculation views. Each view type provides a distinct purpose and can be utilised to accomplish various data modeling scenarios.
Ans: ABAP on HANA provides quicker data processing, better memory utilisation, and real-time analytics. It enables the integration of SAP HANA in ABAP-based applications, allowing users to benefit from the power of HANA's in-memory database technology.
Ans: Views in SAP HANA can be of three types: attribute views, analytic views, and calculation views. For master data, attribute views are employed, analytic views for transaction data analysis, and calculation views for complicated data modelling.
Ans: Techniques such as push-down processing, parallel processing, and partitioning can be used to assure good performance in ABAP on HANA. You can also improve SQL queries and employ cutting-edge programming paradigms like ABAP Objects.

Ans: Open SQL is a subset of standard SQL that SAP's ABAP system supports. It acts as a barrier between the ABAP programme and the underlying database. Native SQL, on the other hand, provides direct database access and supports all SQL features.
Ans: Indexes supported by SAP HANA include column store indexes, row store indexes, and full-text indexes. Column store indexes are designed to support analytical queries, whereas row store indexes are designed to support transactional processing.
Ans: You can use Eclipse's ABAP Development Tools (ADT) to construct an ABAP programme in SAP HANA. You can start a new ABAP project, choose a package, and write a new ABAP programme.
Ans: A CDS (Core Data Services) view is a data view defined using the CDS language. CDS views define data models in SAP HANA in a standardised manner, allowing for easy reuse and consistency across applications.
Ans: A function module is a reusable piece of code that accomplishes a specified goal. It can be accessed with any ABAP programme. A BAPI (Business Application Programming Interface) is a standardised interface that allows you to access SAP business objects. BAPIs are intended to be used by third-party apps.
Ans: A stored procedure is a precompiled code block that may be run in SAP HANA. It is often used to execute complex data processing activities such as aggregations and calculations, and it may be accessed through ABAP programmes.
Ans: Variables supported by ABAP on HANA include local variables, instance variables, and static variables. Local variables are declared inside the scope of a method or subroutine, whereas instance variables are declared within the scope of a class. Static variables are shared by all instances of the same class.
Ans: The ABAP Managed Database Procedure (AMDP) is a method for running SQL queries in SAP HANA. It enables ABAP developers to construct SQL procedures in ABAP syntax and seamlessly incorporate them into ABAP programmes.

Ans: Push-down processing, parallel processing, and partitioning can all be used to improve performance in ABAP on HANA. You may also optimize SQL queries, employ ABAP Objects and CDS views to reduce network latency, minimize data transfer between the application server and the database, and take advantage of HANA-specific features like in-memory column storage and predictive analysis.
Ans: A database table is one that is kept in the SAP HANA database. It can be accessed directly using SQL or indirectly through ABAP programmes. A transparent table is a database table that may be accessed through ABAP Dictionary objects like data elements and domains.
Ans: To monitor performance in ABAP on HANA, you can utilise tools such as the ABAP Profiler, the SQL Monitor, and the HANA Studio. These tools enable you to discover bottlenecks in performance, optimise SQL queries, and monitor system health.
Ans: In SAP HANA, a client-dependent object is one that is unique to a given client. It is saved with a client-specific identity in the SAP HANA database. A client-independent object is one that is shared by all SAP HANA clients. It is saved with a global identifier in the SAP HANA database. User master records are examples of client-dependent objects, whereas data models and calculation views are examples of client-independent objects.
Ans: The integration of SAP's ABAP programming language with SAP HANA's in-memory database technology is referred to as ABAP on HANA. This interface enables ABAP developers to use HANA's capability for quicker data processing, better memory use, and real-time analytics.
Ans: SAP's proprietary programming language, BAP, is used to create applications for the SAP platform. The usage of ABAP in conjunction with SAP HANA's in-memory database technology is referred to as ABAP on HANA. ABAP on HANA enables quicker data processing, better memory utilisation, and real-time analytics.
Ans: S/4 HANA is the most recent version of SAP's ERP system, and it is built on SAP HANA's in-memory database technology. Its goal is to provide real-time business information while also streamlining company processes.
Ans: Some popular SAP HANA interview questions include:
Ans: SAP HANA's three primary system components are as follows:
