- source data structures (in form of CREATE TABLE please)
- actual whole query that creates duplicates

I am trying out the crosstab function (tablefunc contrib) for reporting needs and I'm having a problem.
I have customers and products and the data is the quantity purchased. I am grouping by customername, productname in the source sql. My category sql depends if I want the products or customers to be the columns.
When I make customers the rows and products the columns, it works fine. But when I make customers the columns and products the rows, there are duplicate product rows.
Is there a way to group the product rows so that the data results come back correct?
