Teradata 错误有序分析函数在 group by 子句中不允许

Question

我收到了错误：

Ordered Analytical Function not allowed in group by clause 

用于以下查询。

SELECT 
CC.CASE_ID as CASE_ID,
FIRST_VALUE(CC.CASE_OWN_NM) OVER(PARTITION BY CC.CASE_ID )as    FST_AGNT_CASE_OWN_NM,
FIRST_VALUE(CC.LSTMOD_BY_AGNT_PRFL_NM) OVER(PARTITION BY CC.CASE_ID)as  FST_AGNT_PRFL_NM,
