When using incremental aggregation, you apply captured
changes in the source to aggregate calculations in a
session. If the source changes only incrementally and you
can capture changes, you can configure the session to
process only those changes. This allows the Informatica
Server to update your target incrementally, rather than
forcing it to process the entire source and recalculate the
same calculations each time you run the session.

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
