Table/view &1 contains a GUID (field &2) in the key

What causes this issue?

The table/view &V1& has a GUID in its key.
GUIDs are unique (generated) values which should have no meaning in the
customizing environment, although they are only forbidden in the keys of
views/tables with generated maintenance dialogs. You can put the keys of
other (database) tables, i.e. tables without generated maintenance
dialogs, in BC Sets.

System Response

This is a table/view with a generated maintenance dialog. You cannot use
it in BC Sets.

How to fix this error?
