• What is the cause and solution for SAP error message OO629 - The superclass of a persistent class must be persistent ?

  The SAP error message OO629 indicates that there is an issue with the inheritance structure of a persistent class in the ABAP Object-Oriented programming environment. Specifically, it means that the superclass of a persistent class is not itself a persistent class, which violates the rules of the ABAP Object-Oriented model.
  
  Cause:
  
  Non-Persistent Superclass: The superclass of the class you are trying to define as persistent is not marked as persistent. In ABAP, a persistent class is one that is intended to be stored in the database, and its superclass must also be persistent to ensure that the entire inheritance chain is valid for database storage.
  Incorrect Class Definition: The class definition may have been incorrectly set up, where the superclass is either not defined as persistent or is a local class that cannot be persistent.
  
  
  Solution:
  
  Check Superclass Definition: Verify the definition of the superclass. Ensure that it is declared as a persistent class. You
