• What is the cause and solution for SAP error message CME_DTYPE016 - Check class & has to inherit from class & ?

  The SAP error message CME_DTYPE016 indicates that there is an issue with the inheritance of a class in ABAP (Advanced Business Application Programming). Specifically, the error message states that a class you are trying to define or use does not properly inherit from the specified parent class.
  Cause:
  The error typically occurs due to one of the following reasons:
  
  Incorrect Class Declaration: The class you are trying to create or use does not correctly declare its parent class in the INHERIT FROM clause.
  Non-existent Parent Class: The parent class you are trying to inherit from does not exist or is not accessible in the current context.
  Visibility Issues: The parent class may not be visible due to access restrictions (e.g., it is declared as private or protected).
  Typographical Errors: There may be a typo in the class name, leading to the system not recognizing the intended parent class.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Class Declaration:
  
  Ensure that the class you are defining correctly specifies the parent class in the INHERIT FROM clause.
  Example:
  CLASS my_subclass DEFINITION INHERITING FROM my_parent_class.
  
  
  
  
  Verify Parent Class Existence:
  
  Confirm that the parent class you are trying to inherit from actually exists in the system.
  You can do this by checking the class in the ABAP Class Builder (transaction SE24).
  
  
  
  Check Access Modifiers:
  
  Ensure that the parent class is declared with the appropriate visibility (public, protected) that allows the subclass to inherit from it.
  
  
  
  Correct Typographical Errors:
  
  Double-check the spelling of the class names to ensure there are no typographical errors.
  
  
  
  Recompile the Classes:
  
  If you have made changes to the class definitions, make sure to activate and recompile the classes to reflect the changes.
