所有未聚合的列都必须包含在GROUP BY子句中，这意味着它应该看起来像这样；请注意，必须删除列别名！

GROUP BY dha.order_number,
         dha.ordered_date,
         dha.org_id,
         houf.name,
         dha.TRANSACTIONAL_CURRENCY_CODE,
         dla.ORDERED_QTY,
         dla.UNIT_SELLING_PRICE,
         esib.item_number,
         esit.description,
         hca.account_name,
         hzps.PARTY_SITE_NAME,
         cicev.UNIT_COST_AVERAGE

除此之外，不需要DISTINCT(in SELECT) 因为GROUP BY无论如何都会选择不同的值。

[编辑：如何在 WHERE 子句中包含新条件？]

select ...
from ...
where cicev.cost_date = (select max(cicev1.cost_date)
                         from CST_ITEM_COST_ELEMENTS_V cicev1
                         where cicev1.inventory_item_id = cicev.inventory_item_id
                        )
  and ...
