• What is the cause and solution for SAP error message SF683 - A subnode cannot be assigned to a reference to a structure ?

  The SAP error message SF683, which states "A subnode cannot be assigned to a reference to a structure," typically occurs in the context of SAP ABAP programming, particularly when dealing with data structures and references.
  
  Cause:
  This error usually arises when there is an attempt to assign a subnode (or a field) of a structure to a reference variable that is expected to point to the entire structure rather than just a part of it. In ABAP, a reference variable must match the type of the data it is pointing to, and if you try to assign a subfield to a reference variable that is not compatible, this error will be triggered.
  Example Scenario:
  Suppose you have a structure defined as follows:
  TYPES: BEGIN OF ty_example,
           field1 TYPE i,
           field2 TYPE c LENGTH 10,
