A reference type is a reference to a different type. You use a reference type to define the type of reference variables in ABAP Objects . There are several kinds of reference types:

  • Reference to a class or an interface
  • Reference to a type defined in the Dictionary
  • Generic reference to ANY, OBJECT or DATA. A reference of type ANY can point to objects as well as to data.
  • Reference to a predefined Dictionary type including the length specification and possibly the decimal places.
