Origin of ABAP in SAP R/2:

ABAP was introduced in 1983 with SAP R/2, and its mainframe predecessor to R/3. In the beginning, it was created as a reporting language, which allowed users to generate custom reports from SAP data, and there was no need for direct access to database tables. This early version provided basic programming constructs and database access capabilities. 

Evolution through SAP R/3

The launch of SAP R/3 in 1992 was a great period for ABAP. This is how the language gets changed from a simple reporting tool into a complete programming platform that supports client-server architecture. This evolution enabled developers to build more sophisticated, maintainable applications.

ABAP in SAP S/4HANA Environment

From the day S/4HANA's introduced in 2015, ABAP went through another transformation. This language gets adjusted to use SAP HANA in-memory computing capabilities, which introduces CDS (Core Data Services) views, AMDP (ABAP Managed Database Procedures), and the RAP (RESTful ABAP Programming) model.

ABAP Architecture and Environment

Three-tier SAP Architecture

SAP systems follow a three-tier architecture that separates concerns and enables scalability. T understand this one can take the course of SAP ABAP Certification, where they can learn about this.

• Presentation Layer:

This includes SAP GUI, Web Browser, and Fiori Apps

User interface and interaction.

• Application Layer

ABAP Application Server, Business Logic

Processing business transactions and rules

• Database Layer

SAP HANA, Oracle, DB2, SQL Server

Persistent data storage and retrieval.

ABAP Runtime Environment

• ABAP Kernel:

It is the main engine that runs ABAP programs, which manages memory and controls system resources.

• Work Processes:

These are some of the different units that run tasks such as handling user requests and system jobs that include:

• Dialog: Handles user interaction.
• Background: Runs tasks in the background.
• Update: Updates data.
• Enqueue: Manages locks to avoid conflicts.
• Spool: Manages printing tasks.
• Memory Management:

This system caan help in managing the memory effectively. This includes the different memories, such as:

• User context: Stores user-related data.
• Roll area: Stores temporary data for active users.
• Extended memory: Stores data used by the system.
• Heap memory: Stores general data to help speed up processes.

SAP Systems and Landscapes:

The SAP environment includes multiple systems that form a world. So let’s understand this:

Development Environment and Tools:

ABAP Development Tools:

ADT is all about the modern approach to ABAP development that is built on the Eclipse IDE platform. Also, it offers advanced features such as code completion, refactoring tools, integrated debugging, and smooth integration with version control systems. Well, ADT is the most preferable tool for our S/4HANA development and supports modern ABAP development paradigms like CDS views and RAP.

SAP GUI:

It is the traditional way of accessing the AABAP development tools. Even though it is older than ADT (ABAP Development Tools), it is still commonly used to work with traditional systems and run classic transaction codes.

ABAP Workbench:

It is a collection of tools that can help developers to write and manage ABAP code.

• SE80 Object Navigator: 

This is the main tool used for finding and editing all ABAP objects (things like programs, functions, etc.).

• ABAP Editor (SE38/SE80): 

This is the code editor where developers write ABAP code. It highlights syntax, organizes code, and has a built-in debugger to find errors.

• ABAP Dictionary (SE11): 

This tool helps manage the database. It’s used for creating tables, views, data elements, and domains.

• Function Builder (SE37):

This tool helps create and manage function modules (small pieces of reusable code) and function groups (groups of related functions).

ABAP Syntax and Concepts

ABAP is best at employing the distinct structure and the programming concepts:

• Data types and Variables:

This complete system includes the elementary types (C, N, D, T, I, F), complex types (structures, internal tables), and reference types.

• Internal tables and work areas:

Dynamic data structures similar to arrays that can store multiple records, with different table types (standard, sorted, hashed) optimized for different access patterns

• Control statements:

 IF-ENDIF, CASE-ENDCASE, LOOP-ENDLOOP, WHILE-ENDWHILE for program flow control

• Modularization techniques:

Subroutines (FORM-ENDFORM), function modules, methods in classes, and macros for code reusability and maintainability.
