I found somewhere that if we wish to have sum of a particular field then we can write this kind of expression:
[[ reduce(lambda x, obj:x obj.amount_total, invoice,0) ]].
Does any one knows if its correct or the correct expression. In my case i want sum of amount_total in invoice not lines the only invoice object. Please help.
