Guidelines for Creating a New One-To-One Extension Table

In most situations, you must extend the base table or reuse an ATTRIB column on a one-to-one extension table. Rare instances exist when you must create a new one-to-one table, such as to add a LONG column because you cannot add it to a base table and because Siebel CRM supports only one LONG column on a table. For more information, see Creating a LONG Column on an Extension Table.
