LineItem.priceAfterAllDiscountsBeforeTaxesSet field now available

The LineItem object in the GraphQL Admin API now includes a [priceAfterAllDiscountsBeforeTaxesSet(https://shopify.dev/docs/api/admin-graphql/2026-07/objects/LineItem#field-LineItem.fields.priceAfterAllDiscountsBeforeTaxesSet) field, which is equivalent to the REST API's current_subtotal_price_set on line items. This field returns the total price of a line item in both shop and presentment currencies after all discounts have been applied, excluding refunded and removed quantities. The value doesn't include taxes.

This is useful for order export workflows where you need the line-level subtotal after discounts but before tax.
