You can make it by adding date_histo to column then right click and choose month then right click on Cust_Nb Winsum and select compute pane down.
another option is right click on Cust_Nb Winsum and edit table calculation ->advanced -> select month (date_histo)
hope this will help you

Thank you indumon.
1- you are quick
2- you are right
Yhis works when I use Tableau Desktop, but I wonder if there would be a way to have that within a calculated field.
I am publishing data connections to Tableau Server and I am not sure that Tableau Server (8.0) can do this.
Even if it can, I am not sure to be able to explain all my users how to male it.
Anyway, this helps a lot!
