Get the complementary attributes from services to proposals

Using my Dolibarr

I created several complementary attributes attached with services, now I want to cite them in proposals in odt template and they didn’t show, do I need to fetch the same attributes to proposals? and how?

Thanks

Hello,

Have you tried :
{line_product_options_xxx} : If the line is a product, Value of the Product extra filed (where xxx is code of Product extra field) ?
