• What is the cause and solution for SAP error message OO192 - Superclass of an exception class must be an exception class ?

  The SAP error message OO192 indicates that there is an issue with the inheritance of exception classes in ABAP (Advanced Business Application Programming). Specifically, it means that the superclass of an exception class you are trying to define or use is not an exception class, which is a requirement in ABAP.
  Cause:
  The error occurs when you attempt to define an exception class that extends a superclass that is not an exception class. In ABAP, all exception classes must inherit from the base class CX_STATIC_CHECK or CX_DYNAMIC_CHECK, which are the standard exception classes in the ABAP Object-Oriented framework.
  Solution:
  To resolve this error, you should ensure that the superclass of your exception class is indeed an exception class. Here are the steps to fix the issue:
  
  
  Check the Superclass: Review the definition of your exception class and check the superclass you are trying to extend. Make sure it is either CX_STATIC_CHECK, CX_DYNAMIC_CHECK, or any other class that is derived from these exception classes.
  
  
  Modify the Inheritance: If the superclass is not an exception class, you will need to change the inheritance to a valid exception class. For example:
  CLASS my_exception DEFINITION INHERITING FROM cx_static_check.
  
  
  Recompile the Code: After making the necessary changes, recompile your code to ensure that the error is resolved.
  
  
  Test the Exception Handling: Once the changes are made, test the exception handling in your program to ensure that it behaves as expected.
  
  
  Related Information:
  
  Exception Handling in ABAP: Understanding how exception handling works in ABAP is crucial. You can refer to the SAP documentation on exception handling for more details on how to define and use exception classes.

  SAP Community and Forums: If you continue to face issues, consider reaching out to the SAP Community or forums where you can find discussions and solutions related to similar problems.
