What causes this issue?

While checking the screen, the system discovered that the screen
administration information (entry in table D021S) is either seriously
damaged or missing altogether.

System Response

Even if the entry in table D021S still exists, the screen has been
destroyed from the point of view of the system.
The system requires at least the program name and screen number to be
able to identify a screen. One of these parameters is missing or cannot
be interpreted, so the system cannot allow you to edit the screen.
If the message appears when you try to display versions of the screen,
the screen was already deleted when you called this version.
If the message appears when you compare two versions, the screen was
already deleted in at lease one of the two versions when you called
them.
