Marco,
Do you think it's a good idea to add an ability to filter the data before compare in the "Data Compare" dialog?
Andrew

I support this idea

I think it's a good idea. I have added this to the list of enhancement requests.

I would like to be able to exclude columns as well as rows from "Data Compare". Would also like to be able to compare tables and columns that are differently named on source and target and just be able to tell in the dialogue, which tables and columns need to match with each other.
