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
