Hi,

You simply place the subreport on the page header
an maybe use its <printWhenExpression>
to display it only once, on the first page or whatever.
If it is about displaying it only on the first page,
then you might as wel consider placing it on the
title section of the report.

For details about how to use subreports, check
the supplied "subreport" sample.

I hope this helps.

ur right I need only once.....I tried placing subreport on title but it never finished compiling, then I put it on title and changed the subreport band to details then data is visible but report design goes for a toss.........

and what should the "print when expresion " have?

Its urgent..............

Hi,

It would be interesting to see the report compilation
error before going to complicate things with the
printWhenExpression.
However, such an expression should check the
PAGE_NUMBER variable like this:

<printWhenExpression>
new Boolean($V{PAGE_NUMBER}.intValue() == 1)
</printWhenExpression>

I hope this helps.

Hi,

You are no supplying to your report any
data source.
You are only supplying a parameter
called "InvoiceNumber" and I'm not sure what
the subreport is supposed to do with it.

You have to use either <connectionExpression>
or <dataSourceExpresison> tags so that the
subreport could iterate on something.
Since I see that the subreport does not have
an SQL query, I guess it is the
<dataSourceExpression> that you nees to pass
in to the subreport a custom JRDataSource object.

Anyway, if you want a report/subreport to generate
something even if there are no records in the data
source (null data source in you case),
use whenNoDataType="AllSectionsNoDetail".
If you do that for your subreport, you can see it
is there, but it has no records.

I hope this helps.
Teodor
