How does the sequence generator in Informatica used to populate the ROW_WID column ?
Customer noticed that the sequence generator in Informatica that is used to populate the ROW_WID column of any dimensional table is incremented on every ETL run. Is this by design? This seems like it will become an issue. The impact of this if an incremental load is run multiple times a day, the sequence generator will eventually hit the End Value and when that happens, new records will cause the mapping to fail. Also, the ROW_WIDs of new records will not be sequential.
