• What is the cause and solution for SAP error message SB516 - A superclass is not permitted for class &1 ?

  The SAP error message SB516, which states "A superclass is not permitted for class &1," typically occurs in the context of ABAP programming when there is an issue with the class hierarchy in object-oriented programming. This error indicates that the class you are trying to define or use is incorrectly inheriting from a superclass that is not allowed.
  Cause:
  
  Invalid Superclass: The class you are trying to define is attempting to inherit from a superclass that is not permitted. This can happen if the superclass is not defined as a valid superclass for the class you are creating.
  Abstract Classes: If the superclass is an abstract class, and you are trying to instantiate it directly or use it in a way that is not allowed.
  Incorrect Class Type: The superclass might be a type that does not support inheritance, such as a structure or a non-object-oriented type.
  Namespace Issues: If the class is defined in a different namespace or package that does not allow for inheritance.
  
  Solution:
  
  Check Class Definition: Review the class definition of the class you are trying to create. Ensure that the superclass you are trying to inherit from is a valid class and is defined correctly.
  Use Valid Superclass: If the superclass is not valid, change the inheritance to a valid superclass that is allowed for the class you are defining.
  Abstract Class Handling: If the superclass is abstract, ensure that you are not trying to instantiate it directly. Instead, create a subclass that implements the abstract methods.
  Namespace Verification: Ensure that the class and its superclass are in compatible namespaces and that the necessary authorizations are in place.
  Check for Typographical Errors: Sometimes, the error can be due to simple typographical errors in the class name or the superclass name.
