Hai frnds,
According to my knoweledge,active t/f means which changes the number of rows that can pass through it.
coming to why union t/s is active.......because union t/f merges the data which is coming from two sources,it means that it summarizes the data which is passing through union t/f,with this the no.of rows coming from that will be less....
so it is an active t/f...

Thanks.....Raji

Hi, In source I have records like this No name address 10 manoj mum 10 manoj dilhi 20 kumar usa 20 kumar Tokyo I want records in target like shown below No name addr1 addr2 10 manoj mum dilhi 20 kumar usa Tokyo If it is reverse we can do this by using Normalizer transformation by setting occurance as 2.

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
