OGG-05510
The CSN value {0} given with the ATCSN or AFTERCSN option is less than a CSN value {1} already committed by the previous instance of this process to at least one output trail file. Some transactions associated with the given CSN might be skipped, but others cannot be skipped because they have already been committed to a trail.
Cause
START EXTRACT was issued with an ATCSN or AFTERCSN option, but the specified CSN value is lower than the highest CSN that has already been committed to at least one of multiple output trails. This same specified CSN value is also higher than the highest CSN already committed to least one of the same set of multiple output trails. Some transactions might be skipped, but other transactions that were already committed to a trail during the previous process run cannot be skipped.
Action
None.
