Evaluating ABAP's Diversity: An All-Inclusive Guide to SAP Developmen
ABAP (Advanced Business Application Programming) is a high-level
programming language created by the German software company SAP. ABAP programs
are used primarily for developing applications within the SAP environment.
There are several types of ABAP programs, each serving different purposes and
designed to address specific requirements within SAP systems.
Enrol in our comprehensive SAP ABAP online course
to learn the intricacies of advanced business application programming. Our
course will teach you the fundamentals of SAP application development, such as
creating executable programs and reusable modules and implementing object-oriented
programming concepts.
Some common types of ABAP programs include
1) Executable programs (type 1):
These are stand-alone programs
that can be run independently.
They are commonly used for batch
processing, report generation, data conversion, and other tasks that require
stand-alone execution.
2) Include programs (type 1):
Include programs are reusable
code snippets or modules that can be inserted into other ABAP programs using
the INCLUDE statement.
They encourage code reuse and
maintainability by enabling developers to modularize their code.
3) Function Modules (Type 2):
Function modules are reusable
procedures or functions that encapsulate specific business logic or
functionality.
They can be called from other
ABAP programs, external systems, or within SAP applications.
4) Subroutine pools (type 1):
Subroutine pools contain reusable
subroutines that can be called by ABAP programs running in the same pool.
They are useful for modularizing
code and encouraging reuse within a specific program context.

5) Class Pool Programs (Type 1).
Class pool programs include ABAP
Objects classes and methods.
They define and implement
object-oriented programming concepts like classes, inheritance, polymorphism,
and encapsulation in the ABAP environment.
6) Dialog programs (type 1):
Dialog programs are interactive
applications that enable users to interact with SAP systems via a user
interface.
They typically use screen
layouts, input fields, and logic to process user input and respond
appropriately.
7)WebDynpro ABAP (Type 2):
Web Dynpro ABAP is a framework
for developing web-based applications on the SAP NetWeaver platform.
It enables developers to create
user interfaces using a declarative programming model while seamlessly
integrating with backend ABAP logic.
8)Business add-ins (BAdIs):
BAdIs are enhancement points
within SAP applications that enable developers to add custom functionality
without changing the standard SAP code.
They are implemented as ABAP
classes that include predefined interfaces for extending SAP functionality.
