I have the eP options button. I can change this to hard code Payables/general/invoices and it works. However this would mean users would have to change it each time for each type of batch.

I would believe that that %btt option did not work but then why is it listed in the help section under "ePrint Report Codes" which clearly says that "Eprint report codes may be used within Eprint reports and faborites' folder and FILE NAMES."

Also the other user who replied somehow was able to make this work for his system.
