  Key Concepts: 
  A null reference is a type of SAP ABAP runtime environment component that is used to indicate the absence of a valid reference. It is used to represent an object that has not been initialized or has been deleted. It is also used to represent an object that does not exist in the system. 
  
  How to use it: 
  Null references are used in SAP ABAP programs to check if an object exists or not. If the object does not exist, then the program will return a null reference. This can be used to prevent errors from occurring when trying to access an object that does not exist. 
  
  Tips & Tricks: 
  When using null references, it is important to check for them before attempting to access an object. This will help prevent errors from occurring and ensure that the program runs smoothly.
