Hello Karl,
You can create a custom folder (named Tables - partitioned) with the following where clause:
object_type = 'PARTITION'
union
select t.owner, 'TABLE' object_type, t.table_name object_name, o.status
from all_tables t, all_objects o
where t.owner = o.owner
and t.table_name = o.object_name
and o.object_type = 'TABLE'
and t.partitioned = 'YES'
and o.owner = USER
It will shows any partitioned table only.
