hi, thanks for the feedback. I think you mean somethink like this : http://www.friendpaste.com/4cIo2tzKA3epiwLkwPsolA It works yes, but now I need a second phase to invert values/keys and get them in right order. In fact having the possibility to save resukt of first reduce in temporary docs and mapping them to a new result could be a solution. - benoît
