Hi, I have one flatfile as target in a mapping . When i am trying to load data second time into it. The records already is in flatfile is getting override. I don't want to override existing records. Note : we can do this by implementing CDC / Incremental pool logic if target is relational . But this is flatfile. So, even i use this same technique it will override only So what is the solution ? Is there any option at session level for flatfile target ? Advance Thanks

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. Somebody will say use denoralization technique. But as of my knowledge I couldn’t find any denormalization technique. Is there any concept like that? I tryid this seriously but I could find any idea to implement this. Can any one please help me ? Advance Thanks

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

The same value need to be load into these 3 targets . It is loaded like that only but in different order. Why? The order of insertion should be same know for all 3 targets ? Then why the order is changed ? Any one please help me. Advance thanks.
