Display is not possible") typically occurs when there is an issue with the configuration of notification types in the SAP system, particularly in the context of the SAP PM (Plant Maintenance) or SAP QM (Quality Management) modules. This error indicates that the system cannot find a defined interface for the specified notification type, which prevents the display of the notification.
