About Adding a Partition or Subpartition to a Reference-Partitioned Table

A partition or subpartition can be added to a parent table in a reference partition definition just as partitions and subpartitions can be added to a range, hash, list, or composite partitioned table. The add operation automatically cascades to any descendant reference partitioned tables. The DEPENDENT TABLES clause can set specific properties for dependent tables when you add partitions or subpartitions to a master table.
