ORA-32334 cannot create prebuilt materialized view on a table

hi everyone

I am trying to create a materialized view on a prebuilt table but it keeps giving me the error ORA-32334

OERR: ORA-32334 cannot create prebuilt materialized view on a table already

but if i look into the dba mviews the materialized view does not exist

is there anyway to see wich materialized view is referencing this table or delete all materialized views referencing the table

thanks everyone for your help

greetings

mateo.
