• Key Concepts: 
  A stack is a data structure used in the ABAP Runtime Environment (BC-ABA) of SAP software. It is a collection of data elements that are stored and accessed in a Last-In-First-Out (LIFO) manner. The stack is used to store and manage the execution of ABAP programs. 
  
  How to use it: 
  The stack is used to store and manage the execution of ABAP programs. When an ABAP program is executed, the stack stores the program's instructions, variables, and other data elements. The stack also stores the return address of the program, which is used to return control to the calling program when the current program has finished executing. 
  
  Tips & Tricks: 
  When working with the stack, it is important to remember that data elements are stored and accessed in a Last-In-First-Out (LIFO) manner. This means that the last element added to the stack will be the first element accessed when retrieving data from the stack.
