cross tab expansions

omogeneo

Hello,
I'm Giovanni from Roma and I'm a new Birt developper.

I should build a cross-tab report with:
1. a four-levels rows'hierarchy;
2. a drill-down that expands the hierarchy in each row, by clicking a icon
3. a drill-down that, by clicking a single row, expands only this row (once its expansion, I should do the same thing for each row in the hierarchy)..
Now I can do the point 2. (by linking 4 reports, one for each level of the hierarchy)..
How can I do the point 3?? Do some way exists to avoid the building of too much reports??

I hope I make myself clair.
Thanks for regards,
Giovanni

Hi Giovanni,<br />
<br />
You may have already solved your issue, but I'll respond in case anyone else has the same sort of question.<br />
<br />
One way to avoid building multiple reports is to create the different crosstab option in one report and drop the unneeded crosstabs based on a parameter value. The following post from the devShare should help with that.<br />
