SQL Error: ORA-14048: a partition maintenance operation may not be combined with other operations
ORA-06512: [...]
14048. 00000 -  "a partition maintenance operation may not be combined with other operations"
*Cause:    ALTER TABLE or ALTER INDEX statement attempted to combine
           a partition maintenance operation (e.g. MOVE PARTITION) with some
           other operation (e.g. ADD PARTITION or PCTFREE which is illegal
*Action:   Ensure that a partition maintenance operation is the sole
           operation specified in ALTER TABLE or ALTER INDEX statement;
           operations other than those dealing with partitions,
           default attributes of partitioned tables/indices or
           specifying that a table be renamed (ALTER TABLE RENAME) may be
           combined at will
