  Key Concepts: 
  An interface reference variable is a type of variable in SAP's ABAP Runtime Environment (BC-ABA) that allows for the dynamic binding of an interface to an object. It is used to access the methods and attributes of an object without knowing the exact type of the object. 
  
  How to use it: 
  Interface reference variables are declared using the REF TO statement. The syntax for this statement is REF TO . Once declared, the interface reference variable can be used to access the methods and attributes of an object. 
  
  Tips & Tricks: 
  When using interface reference variables, it is important to remember that they can only be used to access methods and attributes that are defined in the interface. If you need to access methods or attributes that are not defined in the interface, you will need to use a different type of variable.
