The Freeze feature protects/locks out data warehouse tables from accidental changes to the data in the target (data warehouse) table. Useful for static tables or tables with historical data that should never be overwritten.
Select Freeze to prevent all changes in ETL+ related to this target table.
When selected the Freeze checkbox doesn't allow any action on the target table. It reezes the (target) table (in the data warehouse). A job on the v2022.08 ETL+ Job Page can includes a frozen target table but log file will record any action on the table with the words “
Skip. This table is frozen."
On the v2022.08 ETL+ Extract, Transform and Load (ETL) Page selecting Freeze on a target table will inactivate the Load All button, the Extract SQL Statement panel, the Design page, and the target table name on the Target Object panel.
