Sap Abap Interview Questions
SAP ABAP interview questions typically cover a range of topics related to Advanced Business Application Programming (ABAP) language and its application within the SAP system. Common questions include querying candidates on their programming knowledge, understanding of key ABAP concepts such as data types, loops, and structures, as well as their experience with SAP development tools like SAP GUI and ABAP Workbench. Interviewers may also inquire about candidates' experience with SAP modules, debugging skills, and familiarity with SAP best practices and design patterns. Additionally, questions related to performance optimization, error handling, and integration with other SAP components are frequently asked during SAP ABAP interviews.

1 - What are the types of data dictionary objects in SAP ABAP?
Data dictionary objects in SAP ABAP include tables, views, data elements, domains, and search helps. Tables store data, views provide a logical view of data from multiple tables, data elements define the field's semantic properties, domains define data types, and search helps provide input help for fields.
2) Explain the difference between a transparent table and a pooled table in SAP ABAP.
Transparent tables in SAP ABAP store application data and have a 1:1 relationship with the database tables. Pooled tables are used to store control data or customizing data and have a 1: n relationship with the database tables, meaning multiple pooled tables share one database table.
3) What is an ABAP program and what are its different types?
An ABAP program in SAP is a logical unit of code that performs a specific task. The different types of ABAP programs include executable programs (report programs), module pool programs, function modules, and classes.
4) How can you debug an ABAP program in SAP?
You can debug an ABAP program in SAP using transaction code SE38 for individual program debugging or by using transaction code SE80 for mass debugging. Additionally, you can set breakpoints, watchpoints, and use debugging tools like the ABAP debugger to analyze the program flow and data.
5) Explain the concept of BDC (Batch Data Communication) in SAP ABAP.
BDC is a method in SAP ABAP used to transfer data from non SAP systems to SAP systems. It involves two techniques: Call Transaction Method, which directly uploads the data to the database, and Session Method, which records the data as a batch input session for processing.
6) What is a function module in SAP ABAP?
Function modules in SAP ABAP are reusable code blocks that can be called from within a program to perform specific tasks. They promote modular programming and encapsulate business logic, making them easily callable and maintainable across different programs.
7) How do you create a new custom table in SAP ABAP?
You can create a new custom table in SAP ABAP using the transaction code SE11. You define the table's structure by specifying fields, keys, and technical settings like the table type. After defining the table, you activate it to create the corresponding database table.
8) Explain the purpose of SAP Smart Forms.
SAP Smart Forms in SAP ABAP are used to design and generate business documents such as invoices, purchase orders, and delivery notes. They offer a user friendly graphical interface for designing forms and provide flexibility in layout design and data retrieval.
9) How do you transport ABAP objects between different SAP systems?
You can transport ABAP objects between different SAP systems using the Transport Organizer (transaction code STMS). You first create a transport request, assign the relevant objects to it, and then release and import the request in the target system to move the objects.
10) What is the difference between a field symbol and a data reference in SAP ABAP?
Field symbols in SAP ABAP are placeholders that point to data objects during program execution, allowing dynamic access and manipulation of data. Data references, on the other hand, are pointers that store the address of a data object in memory and provide indirect access to the data.
