You cannot use FastLoad, MultiLoad, or the Teradata Parallel Transporter operators LOAD and UPDATE to load data into base tables that have hash indexes because those indexes are not maintained during the execution of these utilities. If you attempt to load data into base tables with hash indexes using these utilities, an error message returns and the load does not continue.

To load data into a hash-indexed base table, you must drop all defined hash indexes before you can run FastLoad, MultiLoad, or the Teradata Parallel Transporter operators LOAD and UPDATE.

Load utilities like Teradata Parallel Data Pump, BTEQ, and the Teradata Parallel Transporter operators INSERT and STREAM, which perform standard SQL row inserts and updates, are supported for hash-indexed tables.
