  SAP Error Message:
  WY066 - Possible entries cannot be displayed in display mode
  
  
  Cause:
  This error typically occurs when a user tries to display possible entries (F4 help) for a field in display mode (i.e., when the screen or transaction is in display-only mode). In display mode, the system restricts certain interactive functions such as showing possible entries or value help because the data is not editable.
  In other words, the system prevents the F4 help from being triggered when the screen is set to display mode, as no changes or selections are expected to be made.
  
  Explanation:
