Attributes control technical product characteristics; product options represent buyer-selectable add-ons.
The initial load imports attribute codes, labels, types, scopes, and option values. Use the technical Attribute Code in mappings.
Verify the attribute set.
Map the Magento attribute to a BC field or a variant axis.
Check data type and required status.
Upload a test product.
Options can contain title, type, required status, sort order, prices, and selection values. Test price and tax effects in the cart.
Select/multi-select values must exist as valid Magento options. Free text instead of an option ID can cause invalid variants.
