How to create a report with more than 2 crosstabs

Hello,

I'm new here and new with BI reports.

I have to create a new WebI report and this report must have 3 crosstabs, as structured below:

30min | Dimension1 (crosstab) | Dimension2 (crosstab) | Dimension3 (crosstab)

The values of Dimension1, Dimension2 and DImension3 can be:

1 - Dimension1 (A, B, C, ..., null);

2 - Dimension2 (Blue, Red, Green, ..., null);

3 - Dimension3 (Cat, Dog, Bird, ..., null).

But when I put those dimensions on the report with crosstab layout, it is created with this structure:

30min | null | null | null | A | B | C | Blue | Red | Green | Cat | Dog | Bird

How can I make my report with each crosstab separeted by dimension:

30min | null | A | B | C | null | Blue | Red | Green| null | Cat | Dog | Bird

I'm using RichClient and BO 4.1.

Thanks,

Alan
