  Key Concepts: 
  A session variable is a type of variable in SAP that is used to store values for a particular user session. It is stored in the database and can be accessed by any program running in the same user session. Session variables are used to store information that needs to be accessed across multiple programs or transactions. 
  
  How to use it: 
  Session variables can be used to store values that need to be accessed across multiple programs or transactions. For example, if a user needs to access a certain value from one program and use it in another, they can store the value in a session variable and access it from any program running in the same user session. 
  
  Tips & Tricks: 
  When using session variables, it is important to remember that they are only accessible within the same user session. If the user logs out or closes the program, the session variable will no longer be accessible. Additionally, it is important to remember that session variables are stored in the database and can be accessed by any program running in the same user session, so it is important to ensure that only necessary information is stored in them.
