datasource aggregates the results of my query

Hi.
I have a problem with the BI server. that's what :)
The datasource is a simple query, "select * from my_table" and my_table (my_table is a view)is:

ID | YEAR | Value_1
---------------------
A001 | 2011 | 3
A001 | 2012 | 5
A002 | 2011 | 2
A003 | 2011 | 6

I can't empty "MEASURES" and so I put only ID.
If I make a simple report from User Console on this datasource, my result is:

ID | YEAR | Value_1
---------------------
A001 | 4023 | 8
A002 | 2011 | 2
A003 | 2011 | 6


There is a way to delete this aggregation? When I create a datasource, it's impossible to create it without MEASURES (I guess it's ID under MEASURES which aggregates my result...).
Thanks in advance, bye :)
