Change excel output file name of BI publisher in Oracle apps

Hi,

I am generating excel output using XML publisher(BI Publisher).

When i click on view output and try to save the file, it is saving with default file name as Program name and with sysdate.

For example it is saving as "xxcustom_report_070818.xls"

we have a requirement, by default the file should be saved as Program name and with sysdate and time stamp.

for example it should save as  "xxcustom_report_070818021153.xls". Here 070818021153 means "mmddyyhhmiss" it is date with time stamp.

This is a customer requirement and they run program and download the output multiple times and each output should save with time stamp.
