Reporting: No Page Header on first page

[Martin Brunner]

Hi there,

It's MD 4. Hosted. I upload the reports.
Studio 2005 - Microsoft SQL Server Reporting Services Designers Version
9.00.4035.00

I've got a pair of RDLs: Invoice (Main) & Invoice Subreport.
If I change the margins in the Subreport I get no difference. I have to do
that in Mainreport. OK.
If I put a header into Mainreport, it occurs on every page. Even if I set
PrintOnFirstPage to false.

How do I properly hide the Page Header on a first page?
What do I have do be aware of?

TNX in advance, Martin (@Vienna@Europe)
