Not sure about your required output. But try using WITH clause query inside SET clause of UPDATE statement.
   UPDATE SALES_REVENUE SR
    SET
             (SR.TODAY_REV,
             SR.TODAY_MARGIN,
             SR.TODAY_UNIT
             ) =
(WITH result_sum_temp
AS(
    SELECT SALE_ID, IN_TEAM, 1 SALE_FLAG, loc, seg,
        SUM(REV * rate) AS sum_rev,
        SUM(MARGIN * rate) AS sum_mar,
        SUM(UNIT) AS SUM_UNIT
    FROM SALES
    WHERE (IGNORED IS NULL OR IGNORED <> 'Y')
    AND SALE_SPOT = 7
    AND SALE_ID = 375
    AND SALE_MODEL = 'D'
    AND IN_TEAM IS NOT NULL AND loc IS NOT NULL
    GROUP BY SALE_ID, IN_TEAM, loc, seg
     UNION ALL
    SELECT SALE_ID, OUT_TEAM, 2 SALE_FLAG, loc, seg,
        SUM(REV * rate) AS sum_rev,
        SUM(MARGIN * rate) AS sum_mar,
        SUM(UNIT) AS SUM_UNIT
    FROM SALES
    WHERE (IGNORED IS NULL OR IGNORED <> 'Y')
    AND SALE_SPOT = 2
    AND SALE_ID = 375
    AND SALE_MODEL = 'D'
    AND OUT_TEAM IS NOT NULL AND loc IS NOT NULL
    GROUP BY SALE_ID, OUT_TEAM, loc, seg)
                (SELECT   t.sum_rev, t.sum_mar, t.sum_unit
                   FROM   result_sum_temp t
                  WHERE       SR.SALE_ID = t.SALE_ID
                          AND SR.team_id = t.team_id
                          AND SR.SALE_FLAG = t.SALE_FLAG
                          AND SR.SEG = t.seg
                          AND SR.loc = t.loc
                          AND t.SALE_ID = 255)
    WHERE   SR.SALE_SPOT = 890
            AND SR.SALE_ID = 255
            AND (SR.SALE_ID, SR.team_id, SR.sale_flag, SR.SEGMENT, SR.LOB) IN
                      (SELECT   SALE_ID,
                                team_id,
                                sale_flag,
                                seg,
                                loc
                         FROM   result_sum_temp));
