Here’s a query you can use to find bad records based on a constraint name (replace the part in red):

select 'select * from ' || dc.table_name || ' where not exists (select 1 from ' || dcc1.table_name || ' where ' || dcc1.table_name || '.' || dcc1.column_name || ' = ' || dcc2.table_name || '.' || dcc2.column_name || ');'
from dba_constraints dc inner join dba_cons_columns dcc1 on dc.r_constraint_name = dcc1.constraint_name
inner join dba_cons_columns dcc2 on dc.constraint_name = dcc2.constraint_name
where dc.constraint_name = 'EDBC_PERS_PERS_FK'
and dc.owner = 'P3_CUR2_TRG'
and dcc1.owner = 'P3_CUR2_TRG'
and dcc2.owner = 'P3_CUR2_TRG';
