Multilevel Report - Sub-Subreport

Hi,

The report that I must create is related to the production order.
Conceptually it can be seen as a tree.
Where the root of the tree are the information Header of the production order.
The principals children of the Root are the Operations and the Requirements to produce such order.
For every Operation they are printed the Plants that are used and the Alternative Resources to effect the production.

There is a method to create a multilevel report?
I think that is not for nothing logical to create a single table containing many heterogenous fields because it would have to repeat already numerous information at the changing of a field.
I have created one datatable for every entity and I have tried to use subreport control, but evidently mistake in something.
In order to obtain the wanted result (for example to print the Order production Head information if the report jump at new page) I have tried to combine the use of List control, Table control and Subreport control in file rdlc, but I have not found the just combination.
Someone of you has already had to crare a multilevel report? Is possible to create a sub-subreport structure?

I have do that in VB.NET with ReportViewer local mode. I have posted the topic in this section because the problem of designe report is the same with local mode and remote mode.



Thanks
