The following are the steps involved:
1. Ensure that the table is replicated via a dedicated named Post queue and that queue does not hold data for any other table.
2. Flush from the Source to the Target.
sp_ctrl> flush o.sourcesid queue <queue_name>
3. Begin an Export of the Source table with FLASHBACK_SCN option in table mode.
4. After the Export is finished on the Source, and after Post stops due to flush on the Target,
compare the Source table to the Target table to make sure both are the same structure (i.e. no DDL changes have occurred).
5. Import the data into the Target table.
6. Disable any triggers or constraints (except PK or UI type) on Target table.
7. Run Reconcile on the Post queue using SCN option and use the same export flashback SCN+1.
8. Start Post on the Target.
