ORA-00959: tablespace '_$deleted$16$0' does not exist

Found error

ORA-00959: tablespace '_$deleted$16$0' does not exist

During add partitioned table: ALTER TABLE ... ADD PARTITION...UPDATE INDEXES

Then checked Oracle Support and fixed issue.
ORA-00959: Tablespace '_$deleted$11$0' Does Not Exist - During DML/DDL On Partitoned Table [ID 1121059.1]
The default tablespace attribute of the table is set to a system generated name that represents a dropped tablespace. (I don't explain... we can read on Oracle Support, that is useful)

On oracle support show idea with partitioned table, we can check on dba_part_tables view

select owner, table_name,def_tablespace_name from dba_part_tables where def_tablespace_name like '%delete%';

and solve by -

alter table table_name modify default attributes tablespace tablespace_existing;

but my issue, that is about partitioned index:

SQL> select owner, index_name,def_tablespace_name from dba_part_indexes where def_tablespace_name like '%delete%';

OWNER TABLE_NAME DEF_TABLESPACE_NAME
------------------------------ ------------------------------ ------------------------------
USER TEST_IND01 _$deleted$16$0
USER TEST_IND02 _$deleted$16$0

SQL> alter index USER.TEST_IND01 modify default attributes tablespace TBS_EXISTING ;

Index altered.

SQL> alter index USER.TEST_IND02 modify default attributes tablespace TBS_EXISTING ;

Index altered.

and then add partitioned table again(no error).
