Hello,
when I run the "Cost Analysis" report for one of my products, the report runs into loop:  gray window with "loading in progress", .... and report never done.
I think there is a bug in the code of the report.
When I try to access the report by "technical" => "view" => "mrp_cost_structure", all is fine but when I go through "technical" => "reports" => "mrp_cost_structure" => "qweb views" I have the following error:

Traceback (most recent call last):

IndexError: list index out of range

Do you have an idea?

thanks,
