I need to be able to concatenate strings from different rows from the same DataSet. I have noticed that there is a Total.concatenate() method but I can't find any information about it. I am not sure what information I need to put in the aggregation wizard.
Where can I find information about this function?

let say I have the following table

customers
---------
Steve
Joe
Denny

I want to display the result as a csv. In this case : Steve, Joe, Denny
