How to suppress page header when records are more under one group 1

[yog2go]

I am creating a purchase order report.
Page header has a company logo and text "Purchase Order".

I have a one group on Purchase order number.

Now for any particular purchase order for example, if it has got lot of items in detail section then it rolls down to next page. In this case page header also displays.
which i don't want to be displayed.

How can i suppress page header in this situation?

Thanks.

In the section expert for the page header next to "supress" create this formula to conditionally supress the page header.

{your.PO#field} = previous ({your.PO#field})


{your.PO#field} represents your group on the PO#.
