  SAP Error Message:
  
  WD449: Clipboard is empty
  
  Cause:
  The error message WD449 - Clipboard is empty typically occurs in SAP Web Dynpro applications when the application tries to access data from the SAP Web Dynpro context or the SAP GUI clipboard, but the expected data is not available or has been lost.
  Common causes include:
  
  The context node or attribute that the application expects to be filled is empty or has not been initialized.
  The data was not passed correctly between different components or views.
  The clipboard (context) was cleared or not set before an operation that requires it.
  Navigation or action logic attempts to read from the context before data is populated.
  In some cases, it can also occur if the user session has expired or the application state is lost.
  
  
  Solution:
  To resolve the WD449 Clipboard is empty error, consider the following steps:
  
  
  Check Context Initialization:
  
  Verify that the context nodes and attributes are properly initialized before they are accessed.
  Ensure that the data is correctly set in the context before any action or navigation that depends on it.
  
  
  
  Debug the Application:
  
  Use the Web Dynpro debugger to check the state of the context at runtime.
  Confirm that the expected data exists in the context nodes/attributes when the error occurs.
  
  
  
  Review Navigation and Data Passing:
  
  Ensure that data is passed correctly between views/components.
  If using plug imports/exports, verify that the data is correctly mapped and transferred.
  
  
  
  Check for Session Timeout:
  
  If the error occurs after a period of inactivity, it might be due to session timeout.
  Refresh the session or log in again.
  
  
  
  Correct Coding Errors:
  
  Look for coding mistakes where the context is cleared unintentionally.
  Avoid accessing context nodes or attributes without checking if they contain data.
