Ralph Kimball's dimensional design approach (the bottom-up design): The data marts facilitating reports and analysis are created first; these are then combined together to create a broad data warehouse. Inmon defines data warehouse as a centralized repository for the entire enterprise.

After a load is done to my target table, I need to insert a last row, which might be formed at some expression transformation and brought to target. Do I have to have separate mapping to be run after the 1st mapping? Or in a single mapping how to achieve this?
