Hi,
I read the openerp-logistics-book.complete and many examples of the book on openerp v7.0 doesn't work. For example in this book explain a module of product margin (product_margin). I have installed this module but doesn't do what is expected. I need to define a margin for my product in percentage. This percentage is the gain that I want to benefit with my product.
Did you ever find a solution to this issue? I too want to set a minimum margin in percentages and yet the system only accepts flat dollar values.
