Before using mapping parameters or variables first we hav to declare them in mapping level.After that we can create parameter file with .txt or .prm extension . Mapping parameters are used when the requirement need the values that cannot change with in session where as mapping variables can change the value with in session the best example for mapping variable are we can use them in concept of Increamental Loading and also to generate sequence numbers with out using sequence Generator Transfomation.

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
