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
