Hi,
Problem: Variant prices, we want fixed prices for each variant not depending on the product price (is put to zero)
Solution: Learned from the Youtube Channel "Odoo avec vous"
https://www.youtube.com/watch?v=-5j7SIriwZ0&t=607s

So to change the variant price we do an export out of the products (not the product variants) and in that way you can import the new prices at
| attribute_line_ids/product_template_value_ids/price_extra |
This is working fine as long as there is only one Attribute. When there is a second Attribute the export looks like this
Suppose the classic T-shirt is in size S, size M, and size L, and those 3 sizes are in 2 colors.
The export file looks like this
__export__.product_template_attribute_value_2034_24044888 Colors: white
__export__.product_template_attribute_value_2033_864d707b Colors; black
__export__.product_template_attribute_value_2025_f32b88aa Size: S
__export__.product_template_attribute_value_2026_3409561d Size: M
__export__.product_template_attribute_value_2027_f7ee323b Size: L
As we try to place a fixed price for each variant, this way of working is not possible anymore.

Do you know how to handle this problem?
Thanks in advance and greetings from Flanders/Belgium
