Parma are now the only side in Group D with a 100 percent record as they came from behind to beat Heerenveen, while Odense and Lens played out a 1-1 draw.
The Dutch outfit made a bright start in Italy as Danijel Pranjic fired Heerenveen ahead on 21 minutes.
The goal served to sting Parma into action as Igor Budan levelled the scores on 24 minutes with a looping header.
And Budan took the game beyond Heerenveen when netting the winner for Parma on 73 minutes, also with his head to book Parma's spot in the last 32.
Lens and Odense are locked together on four points after drawing 1-1.
Tobias Grahn fired Odense ahead shortly before the hour, but Lens battled back to claim a draw thanks to Issam Jomaa's effort on 87 minutes.
