Grid Totals, Information on Collapse Level Line

Hi all,

I would like to generate a grid with information on the line for collapse level. For example the Recommendation Reports of Dunning Wizard and Payment Wizard show this behavior. First the payment no. (= collapse level), then in the following columns information of the BP, the account, etc. After this line comes a new line with detail information. This has the advantage, that if all lines are collapsed, you still have information in the header lines. This is the only useful aspect of using collapse level.

Is it possible and how could it be solved?

Thanks for any suggestions!

Sebastian
