• Key Concepts: 
  Shared memory enabled classes are a type of ABAP class that can be used to store data in a shared memory area. This allows multiple programs to access the same data without having to pass it between them. This is useful for improving performance and reducing the amount of data that needs to be transferred between programs. 
  
  How to use it: 
  Shared memory enabled classes can be used in ABAP programs by declaring a class as shared memory enabled. This will allow the class to be stored in a shared memory area and accessed by multiple programs. The class must also be declared as global so that it can be accessed by other programs. 
  
  Tips & Tricks: 
  When using shared memory enabled classes, it is important to ensure that the data stored in the class is thread-safe. This means that the data should not be modified by one program while another program is accessing it. It is also important to ensure that the data is properly synchronized between programs so that all programs have access to the same version of the data.
