RUN SAP BETTER

SAP ABAP (Advanced Business Application Programming)

 

 

 

It is the name of SAP's proprietary, fourth-generation of a multi-paradigm programming language. It was specifically developed to allow the mass-processing of data in SAP business applications, utilizing procedural, object-oriented, and other programming principles.

 

SAP Objects

​​​​

• API (Application Programming Interface)

• BAPI (Business Application Programming Interface)

  • T-Code: BAPI​

• BAdI (Business Add-In)

  • It is a SAP Object Oriented enhancement technique which is used to add our own business functionality to the existing SAP standard functionality.

• Enhancement Point

  • It is a point in the SAP program where customers can include further functions in the form of source code without modifying the existing program.

  • Enhancement Section: It is the option provided explicitly by SAP to replace a block of SAP code with custom code.​

• Function (FM: Function Module)​

  • T-Code: SE37​

  • Function modules are ABAP routines that encapsulate program code and provide an interface for data exchange. They are stored in a central function library. They are not application-specific and are available system-wide.

• Program​

  • T-Code: SE38​

• Class

  • T-Code: SE24 (ABAP Class Builder)

  • The class is the smallest encapsulation unit in ABAP Objects. A method can therefore use all components of all instances of the same class apart from the components of its own instance.
