Hi,
i wonder what the differences are between single pass and double pass rendering.
When do i use which mode. The documentation lacks of describing those "new" features in 2007.2.
Thanks
Markus

Difference between Single Pass and Double Pass rendering
When you do a single pass, you just print the report. Thats all.
With double pass, you render the report twice. In the first pass you could calculate some sums from groups and in the second pass you could print these sums in the group headers.
Second pass costs twice as much as time, but you can perform calulation that are not possible in a single pass rendering.

Thanks Marco.
I thought this would be the case. So you need it only if you use Event Code or is it also necessary for sums in a group feeter.
So do you have a concrete sample of when to use it?

I think the enige automatically does a double pass when you use TotalPages.
In the first pass, there is no way to know how much pages the rendered report has. Only after the first pass, the value is know and can be printed in the report.
For sum in footers you don't need a double pass, because calulation can be easily made from top to bottom. But when you need to do calculations from bottom to top you need a second pass.
Sorry, I don't have an example, cause I did not need to use the feature so far.
