Rml reports

Question

Hello. I want to modify existing rml template from addons/hr_timesheet_invoice/report/account_analytic_profit.rml
But I have some troubles with following piece of code
[[ reduce(lambda x, y: x+y['unit_amount'], line(data['form'], data['form']['journal_ids'][0][2], data['form']['employee_ids'][0][2]), 0) ]]
I can't understand what *line* function do. Can someone explain it to me?

To find every function that you see in an RML report file you need to seek to the correspondig RML Parser .py. In this case there is at:
addons/hr_timesheet_invoice/report/account_analytic_profit.py
This parser have the function _line made it usable by the RML engine because it's in the report localcontext as 'line'. Just open the source code of this file and read what that function do

Andrew,
are you using Odoo V8? If the answer is yes then you are out of luck, because RML reports are deprecated and on the latest updates of Odoo V8 were not suported anymore. This means RML could suffer from various errors, even if the architecture of your code is right. Better bet on Qweb report for now on.
(the -1 was not mine :P)
