Smart SAP Assistant

• What is the cause and solution for SAP error message IQAPIX161 - check class doesn't inherit from class & ?

  The SAP error message IQAPIX161 indicates that there is an issue with class inheritance in your ABAP code. Specifically, it suggests that a class you are trying to use does not properly inherit from the specified parent class. This can occur in various scenarios, such as when you are trying to implement an interface or extend a class that is not correctly defined.
  Cause:
  
  Incorrect Class Declaration: The class you are trying to use may not be declared correctly or may not inherit from the expected parent class.
  Missing Implementation: The class might be missing the implementation of required methods from the parent class or interface.
  Typographical Errors: There could be typographical errors in the class name or in the inheritance declaration.
  Visibility Issues: The parent class might not be accessible due to visibility restrictions (e.g., it is declared as private or protected).
  
  Solution:
  
  
  Check Class Declaration: Verify that the class you are working with is declared correctly and that it inherits from the correct parent class. Ensure that the syntax is correct.
  CLASS your_subclass_name DEFINITION INHERITING FROM your_parent_class_name.
  
  
  Implement Required Methods: If the parent class or interface has abstract methods, ensure that your subclass implements these methods.
  
  
  Correct Typographical Errors: Double-check the class names and ensure there are no spelling mistakes or incorrect case usage.
  
  
  Visibility Check: Ensure that the parent class is accessible from the subclass. If the parent class is in a different package, check the visibility settings.
  
  
  Recompile the Classes: Sometimes, recompiling the classes can resolve issues related to outdated references.
  
  
  Check for Circular Dependencies: Ensure that there are no circular dependencies between classes that could cause issues with inheritance.
