oracle - SQL join subquery

I tried searching for an answer to my problem but failed to get an answer that actually helped. I've written an sql code but can't seem to find where the problem is. Is it possible to put a subquery in the "FROM" section?

SELECT S2.ITEM,
       S1.SHOP_ORDER,
       S1.OPERATION_NO,
       S1.START_DATE,
       S1.QTY_GOODS,
       S1.QTY_ENTERED,
       S1.QTY_MRB
FROM   (SELECT SHOP_ORD_RPT.OPERATION_NO,
               SHOP_ORD_RPT.SHOP_ORDER
        FROM   FLAME.SHOP_ORD_RPT
        WHERE  SHOP_ORD_RPT.OPERATION_NO = 110
                OR SHOP_ORD_RPT.OPERATION_NO = 370) AS S1
       JOIN (SELECT SHOP_ORD.SHOP_ORDER
             FROM   FLAME.SHOP_ORD
             WHERE  SHOP_ORD.ITEM = '3A2375'
                     OR SHOP_ORD.ITEM = '3A2703')AS S2
         ON S1.SHOP_ORDER = S2.SHOP_ORDER; 

The error I receive upon running the script is:

SQL command not properly ended

I'd appreciate if anyone can help. Thank you very much- Ruth

Try to remove AS keywrod after FROM and JOIN subquery as below

SELECT S2.ITEM, S1.SHOP_ORDER, S1.OPERATION_NO, S1.START_DATE,S1.QTY_GOODS, S1.QTY_ENTERED, S1.QTY_MRB
FROM (
    SELECT SHOP_ORD_RPT.OPERATION_NO, SHOP_ORD_RPT.SHOP_ORDER
    FROM FLAME.SHOP_ORD_RPT
    WHERE SHOP_ORD_RPT.OPERATION_NO =110
    OR SHOP_ORD_RPT.OPERATION_NO =370
    )  S1
JOIN (
    SELECT SHOP_ORD.SHOP_ORDER
    FROM FLAME.SHOP_ORD
    WHERE SHOP_ORD.ITEM ='3A2375'
    OR SHOP_ORD.ITEM ='3A2703'
    )  S2
ON S1.SHOP_ORDER = S2.SHOP_ORDER;
