ORA-19728: data object number conflict between table string and partition string in table string
Cause: The 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.
Action: Use “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.
