比较来自2个不同表的总和

Question

我正在尝试比较A.BUSINESS_UNIT_PO，A.PO_ID，A.LINE_NBR的2个表之间的数量总和。以下查询不适用于我。谁能告诉我这个查询中的问题。

SELECT A.BUSINESS_UNIT_PO,
       A.PO_ID, 
       A.LINE_NBR 
 FROM PS_BCT_DTL A
WHERE A.BCT_DET_STATUS=1
  AND SUM(A.QTY) = (SELECT SUM(B.QTY_SH_RECVD) 
                     FROM PS_RECV_LN_SHIP B
                    WHERE A.BUSINESS_UNIT_PO=B.BUSINESS_UNIT_PO
                      AND A.PO_ID= B.PO_ID
                      AND A.LINE_NBR= B.LINE_NBR
                     )
GROUP BY A.BUSINESS_UNIT_PO,A.PO_ID, A.LINE_NBR

尝试having如下使用：

SELECT A.BUSINESS_UNIT_PO,
       A.PO_ID, 
       A.LINE_NBR,
       SUM(A.QTY) 
FROM PS_BCT_DTL A
WHERE A.BCT_DET_STATUS=1    
GROUP BY A.BUSINESS_UNIT_PO,A.PO_ID, A.LINE_NBR
having SUM(A.QTY) =(SELECT SUM(B.QTY_SH_RECVD) 
                 FROM PS_RECV_LN_SHIP B
                 WHERE A.BUSINESS_UNIT_PO=B.BUSINESS_UNIT_PO
                 AND A.PO_ID= B.PO_ID
                 AND A.LINE_NBR= B.LINE_NBR)
