Bundle Product discounts not saved to quote_item table

[hcmlopes]

Preconditions (*)

1. Magento 2.4.3-p1

Steps to reproduce (*)

1. Create Cart Price Rule for 10%
2. Add Bundle Product to cart
3. Check column row_total_with_discount, discount_amount, base_discount_amount, discount_percent in database table quote_item
4. Check API /rest/<STORE_CODE>/V1/guest-carts/<CART_ID>/totals

Expected result (*)

1. The fields are being calculated properly and stored in the database and therefore are properly returned via API

Actual result (*)

Additional Info (*)

1. Database shows rule 14 should be applied which in this case applies 10%. This can be seen in the checkout where the discount does apply as expected.
   
2. Partially related issue row_total_with_discount not calculated #34288

Expected result

Both items should have their respective discount information. As you can see the bundle product, item_id: 10 in the example, does not have discount_amount, base_discount_amount, percecnt_discount, row_total_with_discount which would be used to properly display line item rows

Hi @hcmlopes ,
We had a confirmation from PO this is not a bug or missed requirement, the intended functionality on the dynamic bundle was to NOT calculate its parent and the luma cart was ignoring those fields in case of bundle.
Hence we are closing it.

Thanks
