Marco,
You should be able to put the aggregates in the cube itself. If you
could put together a csv file I could build an example off of it. I
have posted examples of using the de-api to create a crosstab on birt
exchange, but it is probably better to first design it in the designer
and then use the api to recreate what you want.
