"partitioned index contains subpartitions in a different tablespace"
*Cause: An attempt was made to drop a tablespace which contains indexes
whose subpartitions are not completely contained in this tablespace,
and which are defined on the tables which are completely contained
in this tablespace.
*Action: find indexes with subpartitions which span the tablespace being
dropped and some other tablespace(s). Drop these indexes, or move
the index partitions to a different tablespace, or find the tables
on which the indexes are defined, and drop (or move) them.
