can we load the data with out a primary key of a table?
what is target plan?
Answer Posted / koti
by using update overide option we can update the target
though we dont have any primary key in target.
target overload means some time in a single mapping no. of
targets can take place one source can be depend on other
target. then we have to decide which target has to execute
first....
ex: source1.... target1(date of birth is one column in
target 1)
source2(age is one column is source2).... target2
in the above example target1 should be execute first. then
only we can get age in source 2. because age is depends on
date of birth which is available is target1...
hope u understood. if any clarification mail to me:

Differentiate between joiner and lookup transformation?
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
