Oracle Message ORA-19728 - data object number conflict between table string and partition string in table string

ERRORdata object number conflict between table string and partition string in table string
CAUSEThe non-partitioned table has the same data object number as one of the partitions in the partitioned table. One can not exchange the table with the partition in this case.
ACTIONUse alter table move partition command to move the offending partition, so that the partition will get a new data object number. Retry the operation then.
