Just spent an hour with QB support before seeing this post (saw lots of other posts that didn't address this specific question). I will need to spend quite some hours punching in a couple of years of a nonprofit's budget. I am volunteer, so I don't get paid, but HEY INTUIT this would be a great feature (really, an essential feature) to have to encourage users to migrate from DeskTop. 

Intuit -- you want people to migrate to online -- make the migration easier -- "P/L vs budget by class" isn't the first report we run to verify a clean migration -- a couple of days after migration the shock hits...of course we're upset because we had no clue that QB couldn't handle this seemingly straightforward task.

Kinda wondering what else didn't migrate cleanly that I'll find out about in a few weeks... 

Peace
