  The SAP error message CNV_20100400 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This message indicates that there are unsaved changes in the current session, and the system is prompting the user to decide whether to save those changes or discard them.
  Cause:
  
  Unsaved Changes: The primary cause of this error is that there are changes made in the data entry fields that have not been saved. This can happen if the user navigates away from the screen or tries to execute a function without saving the current data.
  Session Timeout: If the session has been idle for a while, it may prompt this message when the user tries to perform an action.
  Data Migration Process: During data migration, if the user is in the middle of entering or modifying data, the system will alert them to save their work to prevent data loss.
  
  Solution:
  
  Save Changes: If you want to keep the changes you made, click "Yes" to save the data. This will ensure that your modifications are not lost.
  Discard Changes: If you do not wish to keep the changes, click "No" to discard them. Be cautious, as this will result in the loss of any unsaved data.
  Review Data Entry: Before proceeding with any actions, ensure that all necessary data is saved. Regularly save your work to avoid encountering this message frequently.
  Session Management: If you suspect that session timeout is an issue, try to keep your session active by periodically interacting with the system.
