I just exported my pricebook and noticed the dates were wrong:
01-01-2010 in the app is 10-01-01 in the CSV
05-11-2010 in the app is 10-05-11 in the CSV
Maybe that is how you intended, but if you open in Excel it reverses the dates, and 05-11-2010 becomes 10/5/2011. Can you clarify if this is a bug or how you designed it?
Thanks,
Louis
