Use a Target Staging Database with Underlying View Data | Teradata Data Mover - About Using a Target Staging Database When Moving Underlying Data from a View - Teradata Data Mover

If the target table to which the data is being moved exists on the target, Data Mover creates a target staging table to which data is first moved. If copying data to a target view, data is always moved to a target staging table. After data is successfully moved to a target staging table, data from the target table or view is deleted and an INSERT/SELECT or MERGE is performed to move data from the target staging to the target table or view. This is very similar to providing a staging database when moving regular data tables.
