gross_unit_price (BT-148) - rebate (BT-147) = net_unit_price (BT-146)

(2) = quantity = billed_qty
(3) = discount (converted into a percentage) = 100 * (1 - price_subtotal / (billed_qty * price_unit))
(4) = price_subtotal
Alternatively, we could also set: quantity = billed_qty/basis_qty
WARNING, the basis quantity parameter is annoying, for instance, an invoice with a line:
item A | price per unit of measure/unit price: 30 | uom = 3 pieces | billed qty = 3 | rebate = 2 | untaxed total = 28
Indeed, 30 $ / 3 pieces = 10 $ / piece => 10 * 3 (billed quantity) - 2 (rebate) = 28
UBL ROUNDING: "the result of Item line net
amount = ((Item net price (BT-146)÷Item price base quantity (BT-149))×(Invoiced Quantity (BT-129))
must be rounded to two decimals, and the allowance/charge amounts are also rounded separately."
It is not possible to do it in Odoo.
