  Key Concepts: 
  A memory snapshot is a feature of the ABAP Runtime Environment (BC-ABA) in SAP. It is used to capture the state of the system at a certain point in time, including all active programs and their associated memory. This snapshot can then be used for debugging purposes or to analyze system performance. 
  
  How to use it: 
  To take a memory snapshot, you must first enable the feature in the ABAP Runtime Environment. This can be done by setting the parameter “abap/memory_snapshot” to “true”. Once enabled, you can take a snapshot at any time by calling the function module “MEMORY_SNAPSHOT”. The snapshot will be stored in the database and can be accessed via transaction code “SM50”. 
  
  Tips & Tricks: 
  When taking a memory snapshot, it is important to note that only active programs and their associated memory will be captured. Therefore, it is best to take a snapshot when the system is under heavy load or when you are experiencing performance issues.
