In this video you can find how to import from excel in V15 the extra_price field per attribute value in the model “product.template.attribute.value”. 

FYI : For V14, we are currently analyzing the issue.

The main steps are:

1) Go the product menu (note the model = “product.template” > open a product with variants > click on the “Attribute & Variants” tab > click on “configure”

2) You are now in the “product.template.attribute.value” model (see you the URL) > activate the debug mode > hover your mouse over the “value price extra” field > note the field name “price_extra”

3) in debug mode you are able to see the little “bug” icon on top right corner > click on it > click on “edit view: list” > in the architecture tab see in the code “ string="Attributes" create="0" delete="0">” > replace “create=”0” “ by “create=”1” > save, close and refresh your page > now you can see in “favorites” > “imports records” and you have the “create” button appeared

4) Do an export of different attributes value you’d like to update on the “Value price extra” > prepare your export template > update your field “price_extra” on excel > save 

5) Import you excel on the product.template.attribute.value model > the value price extra has been updated by 30$

Note > a big thank you to BEK boss! 

You can note that cannot see the “import records” feature

Replace “create=0” by “create=1”

You can note that my “import records” feature is back now!
