On the eCommerce website of Odoo (version 17) I use Attributes to get versions of a product (Website -> eCommerce -> Attributes -> (my attribute) Size and Material -> Attribute Values -> Default Extra Price). I have defined 6 versions (in Odoo: 'Value') with different prices. On my products (Website -> eCommerce -> Products -> choose a product -> Attributes & Variants) I have added these 6  versions to each product.

OK, now I want to change one Attribute (another price) and I want this to be reflected on each Product that has this Attribute. When I do this on the Attribute page, nothing happens! When I do this on the Product page (Attributes & Variants -> Configure (also called Product Variant Values)) the price of this Product is changed. But how about the other products? Suppose I have 10.000 products, I need to do this 10.000 times! Ridiculous! Isn't the database of Odoo a relational database?

I had a lot of discussion with Odoo Support, but no solution. At the end the suggestion was to upgrade to version 18, as "the functionality of managing the Extra Price directly at the attribute level, rather than at the product level, has been improved starting from version 18.0". I did so, first with a Test database, but the problem persist.

Does anybody know of this problem and has anyone a solution for it? Thanks!

OK, I did try it again on the Test database with version 18 of Odoo. The problem with this Test database is that when you click on a link, it shows the original page, of the version 17 of Odoo! So when I did this again, but carefully watched that I stayed in version 18 with the red band saying TEST, everything works fine! Problem solved.
