This is the syntax to insert into a table from a CTE:
这是从 CTE 插入表的语法：
-- CREATE TABLE tmp ( tmp_id NUMBER(10) );
INSERT INTO tmp( tmp_id )
WITH cte AS (
SELECT 1 AS tmp_id FROM dual
)
SELECT tmp_id
FROM cte;

Seems that Insert cannot be used as first statement after common table expression. Try this,
似乎 Insert 不能用作公共表表达式之后的第一条语句。尝试这个，
INSERT iNTO IPA_PRCADJ_HDR(TRM_CODE,IPAPH_ADJ_FACTOR,IPAPH_AMT_CUR,IPAPH_REMARKS)
SELECT * FROM
(
WITH DTL AS
(SELECT CMPI_CODE,
CMN_CDTY_MTRL,
CMI_WT_FACTOR,
CMI_CNTRCT_RATE,
'PL',
PRESENT_PRICE,
TRM_CODE,
ROUND(((NVL(PRESENT_PRICE,1)*CMI_WT_FACTOR) / CMI_CNTRCT_RATE),2) AS PL_FACTOR
FROM VW_CMD_MATERIAL WHERE TRM_CODE = 41
)
SELECT TRM_CODE,SUM(PL_FACTOR) AS PL_FACTOR,((SUM(PL_FACTOR)*10)) AS AMT_CUR,'asdf'
FROM DTL GROUP BY (TRM_CODE)
);
