Restrictions and Limitations for Load Utilities
You cannot use FastLoad, MultiLoad, or Teradata Parallel Transporter to load data into base tables that have enabled triggers. If you attempt to load data into such tables using any of these utilities, the system returns an error message and the loading process aborts.
You can load data into such base tables if you first disable all triggers on those tables using the ALTER TRIGGER statement (see “ALTER TRIGGER” on page 147) and then run the appropriate data loading utility.
You can then reenable the disabled triggers after the data loading operation completes.
Load utilities like TPump that perform standard SQL inserts and updates can update tables that have enabled triggers.
