Was verursacht dieses Problem?

An aggregate (matchcode object, view, lock object) comprises several
tables which are connected with foreign keys. A primary table is
assumed to which further secondary tables can be added if they are
connected to the primary table with foreign key relationships. There
may be only one path with regard to the foreign key from the primary
table to each of the secondary tables.

Wie behebe ich diesen Fehler?

Please check the foreign key relationships of the tables embraced by
the aggregate. If necessary, you must delete one of the secondary
tables or its foreign key so that the path from the
primary to the secondary tables is unambiguous.
