• What is the cause and solution for SAP error message OO083 - Types cannot be defined as public ?

  The SAP error message OO083, which states "Types cannot be defined as public," typically occurs in the context of ABAP Object-Oriented programming. This error arises when you attempt to declare a type (such as a class or interface) with a visibility modifier that is not allowed in the current context.
  Cause:
  
  Incorrect Visibility Modifier: In ABAP, types (like classes, interfaces, or structures) cannot be declared as PUBLIC in certain contexts, such as within a method or a local class. The visibility modifiers (PUBLIC, PROTECTED, PRIVATE) are only applicable to class definitions and not to local types.
  Local Types: If you are trying to define a type within a method or a local class, it is inherently local and cannot be made public.
  
  Solution:
  
  
  Remove the Visibility Modifier: If you are defining a type within a method or a local class, simply remove the PUBLIC keyword. Local types do not require visibility modifiers.
  Example:
  CLASS my_class DEFINITION.
    PUBLIC SECTION.
      METHODS: my_method.
  ENDCLASS.
  
  CLASS my_class IMPLEMENTATION.
    METHOD my_method.
      TYPES: my_local_type TYPE string. " Remove PUBLIC
      DATA: my_variable TYPE my_local_type.
    ENDMETHOD.
  ENDCLASS.
  
  
  Define Types in the Class Definition: If you need a type to be accessible outside of the class, define it in the class definition under the PUBLIC SECTION instead of within a method.
  Example:
  CLASS my_class DEFINITION.
    PUBLIC SECTION.
      TYPES: my_public_type TYPE string.
      METHODS: my_method.
  ENDCLASS.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation for ABAP programming, which provides guidelines on visibility and type definitions.
  Object-Oriented ABAP: Understanding the principles of object-oriented programming in ABAP can help avoid such errors. Familiarize yourself with the structure of classes, methods, and visibility rules.
  Debugging: If you encounter this error, check the context of your type definition and ensure that you are using the correct visibility modifiers according to the ABAP language rules.
  
  By following these guidelines, you should be able to resolve the OO083 error and correctly define your types in ABAP.
