Hi, The discount field in sale order line and for one order maybe you will have multi lines so you need to calculate all discount amount for each line, You can get the amount before discount in the field  amount_undiscounted and you can add it to the list view. But if you want to to get the total discount amount for the order you need to do your customization and add discount_total_amount to sale order model as computed field as below and then you can add it to the sale order tree view:

discount_total_amount = fields.Float('Discount Amount', compute='_compute_discount_amount', digits=0, store=True)


@api.multi
@api.depends('order_line.price_unit', 'order_line.discount', 'order_line.product_uom_qty')
def _compute_discount_amount(self):
for order in self:
total = 0.0
for line in order.order_line:
total += line.price_unit * ((line.discount or 0.0) / 100.0) * line.product_uom_qty
odrer.discount_total_amount = total

Hello Ricky,

You have to create the tree view of sale order line. I think you can get discount from that.
