Free SAP ABAP Learning Resources: Introduction, Syntax & Roadmap
Genuinely free SAP ABAP learning resources for self-study — ABAP introduction, syntax basics, data dictionary overview, terminology glossary, learning roadmap, interview questions, and sample code. This is not a free training course; it is a collection of free resources to help you start learning ABAP concepts.
Free SAP ABAP introduction
Start here if you are new to ABAP. These free resources explain what ABAP is and where it fits in the SAP ecosystem.
What is SAP ABAP?
ABAP (Advanced Business Application Programming) is SAP's proprietary programming language used to develop and customize SAP applications. It is the technical foundation behind custom reports, enhancements, interfaces, forms, and modern SAP S/4HANA development including CDS Views and OData services.
ABAP vs other programming languages
ABAP is specifically designed for the SAP environment. While it shares concepts with general-purpose languages — variables, loops, conditionals, data structures — it is tightly integrated with the SAP data dictionary and the SAP application framework. You write ABAP to work with SAP business data and processes.
Where ABAP is used
ABAP developers build custom reports for SAP modules like FICO (financial reports), MM (material reports), and SD (sales reports), create enhancements to extend standard SAP functionality, develop interfaces between SAP and other systems, and build modern OData services for SAP S/4HANA applications.
ABAP syntax basics
Free reference material covering the core ABAP syntax you need to start writing programs.
Data types and variables
ABAP uses data types like I (integer), C (character), N (numeric text), D (date), T (time), P (packed number), and STRING. You declare variables using the DATA statement. For example: DATA: lv_name TYPE string, lv_count TYPE i.
Control structures
ABAP supports standard control structures: IF...ELSEIF...ELSE...ENDIF for conditional logic, CASE...WHEN...ENDCASE for multi-branch logic, and DO...ENDDO and WHILE...ENDWHILE for loops. These are the building blocks of program flow in ABAP.
Internal tables
Internal tables are ABAP's core data structure — in-memory tables that hold data during program execution. You declare them with DATA...TABLE OF, fill them with APPEND or INSERT, read them with LOOP AT...ENDLOOP, and access individual rows with READ TABLE. Internal tables are essential for almost every ABAP report.
Work areas and field symbols
Work areas hold one row of an internal table at a time during a loop. Field symbols are ABAP's equivalent of pointers — they reference memory directly and can improve performance when processing large internal tables.
Open SQL
Open SQL is ABAP's database-independent SQL interface. You use SELECT to read from database tables, INSERT to add rows, UPDATE to modify rows, and DELETE to remove rows. Open SQL is translated by the ABAP runtime to the underlying database's native SQL.
Data dictionary overview
The SAP data dictionary (DDIC) is central to ABAP development. These free resources explain its core objects.
Domains
Domains define the technical attributes of a field — data type, length, and value range. They sit at the bottom of the data dictionary hierarchy.
Data elements
Data elements sit on top of domains and add semantic information — field labels and documentation. When you declare a variable using a data element, it inherits both the technical attributes from the domain and the semantic meaning.
Tables
Database tables in SAP are defined in the data dictionary. Each table consists of fields (columns), each of which references a data element. Tables store the actual business data — like material master records or financial documents.
Structures
Structures are like tables but do not store data — they define a temporary data layout used in programs, interfaces, and ABAP Dictionary views.
Views
Views combine data from one or more tables to provide a specific perspective on the data. Database views and maintenance views are common types used in ABAP development.
Key ABAP terminology glossary
A free glossary of essential ABAP terms you will encounter throughout your learning journey.
Data Element
A dictionary object that defines the semantic and technical attributes of a field — combining a domain with descriptive labels.
Domain
A dictionary object that defines the technical attributes of a field — data type, length, and possible value ranges.
Table
A database table defined in the SAP data dictionary that stores business data in rows and columns.
Structure
A dictionary object that defines a data layout without storing data — used in programs and interfaces.
Internal Table
An in-memory data structure in ABAP programs that holds multiple rows of data during program execution.
ALV
ABAP List Viewer — a framework for displaying data in structured, interactive grid or list format in reports.
BAPI
Business Application Programming Interface — a standardized SAP interface that allows external programs to access SAP business functions.
Enhancement
A technique for extending standard SAP functionality without modifying the original code — includes user exits, BAdIs, and enhancement spots.
CDS View
Core Data Services View — a semantically rich data model defined in ABAP on HANA, used for reporting and OData service exposure.
OData
Open Data Protocol — a standard for building REST-based APIs. In SAP, OData services expose CDS Views and other data to frontend applications like SAP Fiori.
AMDP
ABAP Managed Database Procedures — a technique for writing database procedures in ABAP, pushing data-intensive logic to the HANA database layer.
ABAP on HANA
The modern evolution of ABAP optimized for the SAP HANA in-memory database, emphasizing code pushdown and CDS Views.
Beginner learning roadmap
A free step-by-step roadmap to guide your ABAP learning journey from basics to modern ABAP on HANA.
Learn ABAP basics and syntax
Start with data types, variables, control structures, and basic program structure. Write simple programs to get comfortable with ABAP syntax and the development environment.
Understand the data dictionary
Learn about domains, data elements, tables, and structures. Create your own dictionary objects and understand how they relate to ABAP programs.
Master internal tables and Open SQL
Practice declaring, filling, and reading internal tables. Use Open SQL to read from and write to database tables. This is the most-used skill in ABAP development.
Learn modularization
Structure your code using includes, forms, function modules, and classes. Modularization makes code reusable and maintainable.
Build ALV reports
Use the ALV framework to display data professionally. Practice building reports that read from SAP FICO, MM, or SD tables and present data to users.
Study ABAP Objects
Learn object-oriented ABAP — classes, interfaces, inheritance. This is the foundation for modern ABAP development.
Explore enhancements
Learn user exits, BAdIs, and BAPIs to extend standard SAP functionality. Understand how enhancements work without modifying original SAP code.
Move to ABAP on HANA
Study CDS Views, OData services, and AMDP. These are the skills needed for SAP S/4HANA development and are increasingly in demand.
