Assigning Reference Variables Special rules apply when setting the reference or pointer of a reference variable:
Assignment Rules for Reference Variables A reference is always set as an upcast or as a downcast. When a reference variable is assigned to another reference variable, two different assignment operators are used, as well as a constructor operator.
=, ?= - Upcast and Downcast
CAST - Casting Operator References in data reference variables can point to existing data objects. There is a statement and a constructor operator for this.
GET REFERENCE
REF - Reference Operator Like all data objects, reference variables are initialized using the statement CLEAR. The content of an initial reference variable is the null reference , which does not point to an object and can be assigned to every reference variable.#
Latest notes:
The same rules apply to references set when objects are created as to assignments.
When a reference variable containing a heap reference is initialized, this affects Garbage Collector. NON_V5_HINTS ABAP_HINT_END
