ACS - Duplicate profiles after Update action
Hi all,
I can't understand why the Update action in an import workflow duplicates the profiles.
I explain better:
I have this workflow:

The file csv that I have to import has different columns. We have a customer ID, emails, first name and so on.
In the file there are 221.506 profiles with these caractheristics:
- for one email we can have different customer ids ( play@ggg.com can have 5 different customer id)
- for one customer id we can have only one email
The strange thing is when there is a Update action (insert or update profiles) with reconciliation criteria by Customer id and email, the outgoing population is larger than the incoming population.
There are about 500 duplicate profiles.
I can't understand why the update action duplicate the profiles.
Someone have any suggestion?
