A customer asked if it possible to change the default 30 day date range in a report screen. Using a script you can set the From date to any value you wish. Using the Rental Report Screen as an example the script would be:
rentrep.txtStartdate.value = DATE() - 60
Where the 60 value determines how many days back the range goes. This value is 30 by default but you can reset it using this script to any value you want. This approach should work for any report screen.
