What causes this issue?

Inserting a cascading menu in this menu is not allowed.
The nesting depth of menus, including the menu bar, is 4 levels, i.e.
menus at the third level can only contain functions. Since this applies
across the entire user interface, you can still get this error message
while editing a menu in the menu bar. In this case, the message means
that the menu is used at the third level in another menu bar. You can
get more information about this through the where-used list for the
menu.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If the action is rejected because the current menu is still being used
elsewhere, you can copy the menu and use the copy at the current place.
