使用以下示例代码来检查Amdocs计费是否正确：

SELECT 
    po.ORDER_NUMBER,
    SUM(pod.PRICE * pod.QUANTITY) AS TOTAL_PRICE,
    SUM(pod.SHIPPING_PRICE * pod.QUANTITY) AS TOTAL_SHIPPING_PRICE,
    SUM(pod.INSURANCE_PRICE * pod.QUANTITY) AS TOTAL_INSURANCE_PRICE,
    SUM(pod.PRICE * pod.QUANTITY) + SUM(pod.SHIPPING_PRICE * pod.QUANTITY) + SUM(pod.INSURANCE_PRICE * pod.QUANTITY) AS GRAND_TOTAL_PRICE
FROM 
    PURCHASE_ORDER po
    INNER JOIN PURCHASE_ORDER_DETAIL pod ON po.ORDER_NUMBER = pod.ORDER_NUMBER
WHERE 
    po.CUSTOMER_ID = '12345'
    AND po.ORDER_DATE BETWEEN '2019-01-01' AND '2019-12-31'
GROUP BY 
    po.ORDER_NUMBER

此代码将检索在2019年1月1日至2019年12月31日之间针对客户ID为12345的所有订单的总价格，总运费和总保险费用，并计算总费用。如果有任何差异或错误，请检查Amdocs计费以确认正确性。
