When it is clear how a data inconsistency happened, it is sometimes possible to re-synchronize a table faster by manually updating the unrecoverable table. For example, a DBA may manually delete data that was accidentally loaded directly to a system, remove incorrect time ranges, or undo changes that happened outside of Business Continuity Manager. In these situations, once the changes are made, Teradata recommends running a table validation from Business Continuity Manager to activate the table.
