  Key Concepts: 
  An object reference variable is a type of variable in SAP's ABAP Runtime Environment (BC-ABA) that stores a reference to an object. It is used to access the properties and methods of an object without having to create a new instance of the object. 
  
  How to use it: 
  Object reference variables are declared using the REF TO statement. The syntax for this statement is REF TO . For example, if you wanted to declare an object reference variable for a customer object, you would use the statement REF TO CL_CUSTOMER. Once declared, the object reference variable can be used to access the properties and methods of the customer object. 
  
  Tips & Tricks: 
  When using object reference variables, it is important to remember that they do not store the actual data of an object, but rather a reference to it. This means that any changes made to the data of an object through its reference variable will be reflected in all other references to that same object.
