  Key Concepts: 
  Reference type is a feature of the ABAP Runtime Environment (BC-ABA) in SAP. It is used to define the type of reference that is used to access a particular object. This can be either an internal reference, which is used to access objects within the same system, or an external reference, which is used to access objects in other systems. 
  
  How to use it: 
  Reference type can be used to define the type of reference that is used to access a particular object. To do this, you need to go into the ABAP Runtime Environment (BC-ABA) and select the object you want to access. Then, you need to select the type of reference you want to use. You can choose between internal and external references. 
  
  Tips & Tricks: 
  When using reference type, it is important to remember that internal references are only valid within the same system, while external references can be used to access objects in other systems. Additionally, it is important to make sure that the reference type you select matches the type of object you are trying to access.
