• What is the cause and solution for SAP error message WD078 - Names that begin with an underscore are reserved for system events ?

  Certainly! Here's a detailed explanation regarding the SAP error message:
  
  SAP Error Message:
  WD078 - Names that begin with an underscore are reserved for system events
  
  Cause:
  This error occurs when you try to define or use an event name in Web Dynpro (WD) that starts with an underscore (_). In SAP Web Dynpro, event names beginning with an underscore are reserved by the system for internal or system events. User-defined events or custom event names must not start with an underscore to avoid conflicts with these reserved system events.
  
  Explanation:
  
  In Web Dynpro ABAP, events are used to handle user interactions or other triggers.
  SAP reserves event names starting with _ for system-generated or internal events.
  If a developer tries to create or reference an event with a name starting with _, the system throws this error to prevent naming conflicts.
  
  
  Solution:
  
  Rename the event: Change the event name so that it does not start with an underscore.
  Use a meaningful name that starts with a letter or number, but avoid starting with _.
  Check all event declarations, event handler methods, and references in your Web Dynpro component or application to ensure no event names start with _.
  
  
  Related Information:
  
  This naming convention is part of SAP Web Dynpro's design to separate system/internal events from user-defined events.
  Always follow SAP naming conventions for events, methods, and other identifiers.
  If you are importing or copying components, verify that no event names violate this rule.
  This error is specific to Web Dynpro ABAP development and does not generally apply to other SAP development areas.
