My problem was this:
I have a report set up to print one page for each "GSID".
To do this I had the Reprt Title in the page header and a page brea in the Groupfooter.
When I printed for all it was fine, but printing for only one GSID, I always got a second page with only the Rpoert title in the page header.
I solved it like this:
I removed the Page break in the group footer, then forced a page break in code, if not printing from a certain form. (I start a multiple run from one form and a single GSID from another form)
In the On Open event of the Report I
If isloaded("Gesamtübersicht") Then
Me.Gruppenfuß0.ForceNewPage = 0
Else
Me.Gruppenfuß0.ForceNewPage = 2
End If
