Excel Download Top of Page

Hello,

I have a report displayed using function module 'REUSE_ALV_GRID_DISPLAY' and it has a Top of Page event that contains the selection parameters entered by the user.  Method 'CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD' is used to export the data to Excel.  A requirement is to download the Top of Page event data first then followed by the data when exported into Excel into the same file.  Is this possible?  If so, how can it be achieved?

Expected Excel output:

(Data from Top of Page event)

Transaction: XYZ

Account: 1234567890

Date: 8/21/2013

Column1     Column2     Column3

Data1          Data2          Data3

Thanks,

Monica
