• What is the cause and solution for SAP error message PPER3E_CLASS005 - &1 &2 does not allow a reference to a class ?

  The SAP error message PPER3E_CLASS005 typically indicates that there is an issue with the way a class is being referenced in your ABAP code. This error occurs when you attempt to reference a class that does not allow such a reference, often due to visibility or access restrictions.
  Cause:
  
  Visibility Issues: The class you are trying to reference may not be declared as PUBLIC. In ABAP, classes can have different visibility levels (PUBLIC, PROTECTED, PRIVATE), and if a class is not public, it cannot be accessed from outside its own context.
  Incorrect Class Type: You might be trying to reference a class that is not intended to be instantiated or used in the way you are attempting.
  Namespace Issues: If the class is in a different namespace and is not properly imported or accessible, this error can occur.
  Typographical Errors: There may be a typo in the class name or the way it is being referenced.
  
  Solution:
  
  Check Class Declaration: Ensure that the class you are trying to reference is declared as PUBLIC. You can do this by checking the class definition in the ABAP Workbench (SE80 or SE24).
  CLASS my_class DEFINITION
    PUBLIC
    ...
  ENDCLASS.
  
  Use Correct Namespace: If the class is in a different namespace, make sure you are using the correct namespace prefix when referencing it.
  Review Access Modifiers: If the class is intended to be used outside its own context, ensure that all necessary methods and attributes are also declared as PUBLIC.
  Check for Typos: Double-check the spelling of the class name and ensure that it matches the definition exactly.
  Use Proper Instantiation: If you are trying to create an instance of the class, ensure you are using the correct syntax:
  DATA(lo_instance) = NEW my_class( ).
  
  
  Related Information:
  
  ABAP Class Visibility: Understanding the visibility of classes and their components is crucial in ABAP programming. Classes can be defined with different access levels, which control how and where they can be accessed.
  ABAP Workbench Tools: Use transaction codes like SE80 (Object Navigator) and SE24 (Class Builder) to inspect and modify class definitions.
  Documentation: Refer to the official SAP documentation for more details on class definitions and visibility rules in ABAP.
