update strategy transformation?

1. We can define a primary key at the informatica level and configure session properties for Treat rows as "Update as Update" and check the Update check box.
2. If we shud not define the primary key at informatica level, then we can use Update override in Target properties. But i m not very sure of this. Kindly let me know

Hi, I saw one mapping implemented by my seniors . In Expression transformation they implemented following logic. That is iif(is_date(in_UC_DATINV,'YYYYMMDD'),to_date(in_UC_DATINV,'Y YYYMMDD'),'Inventory Date is either invalid or null') Inventory_Date is validated only for is_date() But not validated for notisnull() . But error says “ either invalid or null “ why? Whether is_date() also check for not isnull() ? or in this logic something is different ? Please answer me . Advance thanks
