• Key Concepts: 
  Area classes are a type of ABAP runtime environment component used to define the memory area of an ABAP program. They are used to control the amount of memory that can be allocated to a program, and also to ensure that the program does not exceed its allocated memory. 
  
  How to use it: 
  Area classes are used to define the memory area of an ABAP program. When a program is created, an area class is assigned to it. This area class defines the maximum amount of memory that can be allocated to the program. If the program exceeds its allocated memory, it will be terminated. 
  
  Tips & Tricks: 
  When creating an ABAP program, it is important to assign an appropriate area class. If the area class is too small, the program may not be able to complete its tasks. On the other hand, if the area class is too large, it may cause unnecessary memory usage and slow down the system.
