• What is the cause and solution for SAP error message SAI_MAPPING237 - Class &1 is not public ?

  The SAP error message SAI_MAPPING237, which states "Class &1 is not public," typically occurs in the context of SAP ABAP programming, particularly when dealing with class visibility and access control. This error indicates that the class you are trying to access or use is not declared as public, which means it cannot be accessed from outside its defined scope.
  Cause:
  
  Class Visibility: In ABAP, classes can have different visibility levels: public, protected, and private. If a class is declared as private or protected, it cannot be accessed from outside its defining context.
  Incorrect Usage: The error may arise when you attempt to instantiate or reference a class that is not accessible due to its visibility settings.
  Namespace Issues: If the class is part of a specific namespace and you are trying to access it from outside that namespace without proper authorization or visibility, this error may occur.
  
  Solution:
  
  
  Change Class Visibility:
  
  If you have access to the class definition, you can change the visibility of the class to public. This can be done by modifying the class declaration in the ABAP editor.
  Example:
  CLASS my_class DEFINITION
    PUBLIC
    ...
  ENDCLASS.
  
  
  
  
  Check Class Usage:
  
  Ensure that you are using the class correctly in your code. If the class is not meant to be public, consider using a different class that is accessible or refactor your code to comply with the visibility rules.
  
  
  
  Namespace Considerations:
  
  If the class is in a different namespace, ensure that you have the necessary authorizations to access it. You may need to adjust your code or request access from the system administrator.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or the class documentation to understand its intended usage and visibility settings.
  
  
  
  Contact Developer:
  
  If you are not the developer of the class, reach out to the person or team responsible for it to discuss the visibility settings and whether they can be adjusted.
  
  
  
  Related Information:
