Although you can change some of the characteristics of a table and retain the ability to restore or copy selected partitions to it, other operations on a partitioned table render the table unsuitable for selected partition restorations.

The following table definition changes do not invalidate subsequent restorations of selected partitions for the targeted or referenced tables.

When the target and source are different systems, you must repeat each of the previously listed operations on the affected tables of the target system to ensure that the two are kept in synchrony.

The following ALTER TABLE operations do make any future restore or copy operations of selected partitions for targeted or referenced tables non-valid.

See Teradata Vantage™ - Database Administration, B035-1093 and Teradata® Archive/Recovery Utility Reference, B035-2412 for complete warnings, procedures, and other information related to partial restoration of partitions.
