[POST] .../v1/purchaseoperation/getdiscount
Returns discounts/allowances. Use this method to retrieve discount and allowance operations that belong to receipt-from-partner documents when the client needs to display or recalculate purchase totals. The response returns an array of DiscountOperation records, supports id and document_id filter plus sort_orders and the controller fills the purchase document type internally before querying. The caller must have purchase-operation discount read permission; missing body, denied access, invalid filters or sort_orders and persistent storage failures are returned as HTTP 200 ErrorResult business errors.
