Change Selection Formula after Printing

Hi,

we handle our printing with C#-Code. We set all Information for Printing and set first time the selection formula. Now we start the printing. (We use the internal RAS and also ReportDocumnt.Print(...))

Now we change the selectionformula and print a second time. Now it comes only the skeleton of the report without data.

It is possible to print twice on the same report-object with different selection formula?
