I have a situation here to load the Table into informatica. I have 5 temporary tables as sources. They look like: Table1: (K - Key, N-Null, X,Y,Z - values) K1 X N N N N K2 X N N N N -------------------------- Table2: K1 N X N N N K2 N X N N N -------------------------- the other 3 tables are in the same way. But there can be a situation like any of the table can contain duplicates like: K1 X N N N N K1 Y N N N N -------------------------- This kind of records should be errored out. Because of this, we can't use aggregator/group by as we are not sure which one should be removed. How can we obtain this functionality in Informatica.		View Answer
