What is the SAP ABAP Programming Model?
Thinking of SAP ABAP Online Training? Before enrolling, one must know the basic concept of the SAP ABAP Programming Model and its advanced versions. SAP developed ABAP, a programming language for business applications development in its environment.
One of the fundamental properties of SAP ABAP is that the access to database tables is fully integrated into the language. SAP ABAP provides two programming models i.e.
- Object-oriented programing model – It is based on interfaces and classes
- Procedural programming model – This program is based on subroutines and modules.
Individuals interested in learning SAP Programming Model can either apply online or offline for SAP ABAP Training in Delhi, Noida, or other places after checking the below information mentioned.
Structure of ABAP Processing Logic
Every ABAP program consists of –
Introductory part:- Each ABAP program starts with an initial statement depending on the program type.
Declaration Part for Classes, Global Data, and Selection Screens:- After the introductory part, next is the declaration of classes, global data, and selection screen. It includes all selection screen definitions, word of interfaces, and internal class definitions.
Container for Processing Blocks:- Below the global declaration part, list the processing blocks of an ABAP Program in any sequence in the program’s source code.
ABAP Program Types
Every ABAP Program has a program type. When the program is created, the program type must be determined in the program attribute. There are 7 program types.
- Executable program
- Module pool
- Function group
- Class pool
- Interface pool
- Subroutine pool
- Include program
The program type defines the primary technical attributes of the program. This is how the program is executed and handled, which processing block a program may contain and whether it can work on its screen or not.
