Hi,i strongly advice to use proper set operations to do the transformation. Especially if your data set is not 10, but 10000 rows+.But you can use Generate ID, then Group Into Collection with this id and then Loop Collection to iterate over each row. A simple Loop examples with a Filter Example Range inside would also do it, but is slower than the Group Collection approac.Best,Martin- Sr. Director Data Solutions, Altair RapidMiner -
