• What is the cause and solution for SAP error message OO784 - Event '&' is not contained in the type information ?

  The SAP error message OO784, which states "Event '&' is not contained in the type information," typically occurs in the context of Object-Oriented ABAP programming. This error indicates that the event you are trying to reference or trigger is not defined in the class or interface you are working with.
  Cause:
  
  Undefined Event: The event you are trying to use has not been defined in the class or interface.
  Typographical Error: There may be a typo in the event name you are trying to reference.
  Scope Issues: The event might be defined in a different class or interface that is not accessible in the current context.
  Inheritance Issues: If you are working with subclasses, the event may not be inherited from the parent class.
  
  Solution:
  
  Check Event Definition: Verify that the event you are trying to use is defined in the class or interface. You can do this by checking the class/interface definition in the ABAP Workbench (SE80 or SE24).
  Correct Typographical Errors: Ensure that the event name is spelled correctly and matches the definition exactly, including case sensitivity.
  Review Class Hierarchy: If you are working with inheritance, check the parent class to see if the event is defined there. If it is, ensure that the subclass is correctly inheriting from the parent class.
  Add the Event: If the event is indeed missing, you may need to define it in the class or interface where you intend to use it.
  Check Visibility: Ensure that the event is declared with the appropriate visibility (e.g., public, protected) so that it can be accessed from the context where you are trying to use it.
