Hi,
I am trying to perform a deduplication operation taking email address as the criteria. It has the option to merge the data. I will have one main data and other duplicate data. I want to merge(update) duplicate data field into main data if any of the field of the main data is blank. There is a merge tab in my deduplication activity, but it is not performing deduplication.

can you please suggest how I will be able to achieve this operation.
