Write as asa one insert

Question

Hi,
Need help to write a insert statement instead of insert and update same table.
1) this is my insert statement
INSERT INTO SS_ITEM_STAT_OPN(
        REP_ID, ITEM_ID, REPORT_COLUMN_DISPLAY, REPORT_COLUMN_SEQ_NO, BEGIN_VALUE, END_VALUE)
        SELECT
        LN_SEQ_REP_ID, ITEM_ID, REPORT_COLUMN_DISPLAY, REPORT_COLUMN_SEQ_NO, BEGIN_VALUE, END_VALUE
        FROM VW_SCALE_SCORE_CONFIG CROSS JOIN REP_ITEM_STAT_OPN
        WHERE REP_ID = LN_SEQ_REP_ID;
and  select few values from same table into pl/sql table  for where clause like below
SELECT ITEM_ID, BEGIN_VALUE, END_VALUE
        BULK     COLLECT INTO TV_SS_ITEM_STAT_OPN
        FROM     SS_ITEM_STAT_OPN
        WHERE     REP_ID=LN_SEQ_REP_ID
        ORDER BY REP_ID, ITEM_ID, REPORT_COLUMN_SEQ_NO;and updating using for loop like below
FOR LN_SSI_OPN IN NVL(TV_SS_ITEM_STAT_OPN.FIRST,1)..NVL(TV_SS_ITEM_STAT_OPN.LAST,0)
        LOOP
            UPDATE SS_ITEM_STAT_OPN SET
            TOT_STUD_ITEM_SS             =     NVL((SELECT COUNT(*)
                                            FROM PSYCHOMETRIC_ITEM_STAT_OPN A, VW_SCALE_SCORE_CONFIG B
                                            WHERE    SS_ITEM_STAT_OPN.ITEM_ID=TV_SS_ITEM_STAT_OPN(LN_SSI_OPN).ITEM_ID
                                            AND     (SS_ITEM_STAT_OPN.BEGIN_VALUE=TV_SS_ITEM_STAT_OPN(LN_SSI_OPN).BEGIN_VALUE
                                                    AND    SS_ITEM_STAT_OPN.END_VALUE=TV_SS_ITEM_STAT_OPN(LN_SSI_OPN).END_VALUE)
                                            AND     SS_ITEM_STAT_OPN.ITEM_ID = A.ITEM_ID
                                            AND SS_ITEM_STAT_OPN.END_VALUE = B.END_VALUE
                                            AND ROUND(A.SCALE_SCORE) > BEGIN_VALUE
                                            AND ROUND(A.SCALE_SCORE) <= END_VALUE
                                            AND CONDITION_COLUMN= 'SCALE_SCORE'
                                            GROUP BY ITEM_ID,END_VALUE),0),
            TOT_STUD_CORR_ANS_ITEM_SS     =     NVL((SELECT COUNT(*)
                                            FROM PSYCHOMETRIC_ITEM_STAT_OPN A, VW_SCALE_SCORE_CONFIG B
                                            WHERE SS_ITEM_STAT_OPN.ITEM_ID=TV_SS_ITEM_STAT_OPN(LN_SSI_OPN).ITEM_ID

                                            AND RESPONSE_IS_CORRECT = 1
                                            GROUP BY ITEM_ID,END_VALUE),0),
            TOT_STUD_SS                 =  NVL((SELECT COUNT(*) FROM
                                            (SELECT A.TEST_SESSION_DETAIL_ID
                                            FROM PSYCHOMETRIC_ITEM_STAT_OPN A, VW_SCALE_SCORE_CONFIG B,SS_ITEM_STAT_OPN

            COMMIT;please help to write as a insert statement since this update taking more time.

First inserting below few columns using insert statement usingsub query of anther table .
REP_ID, ITEM_ID, REPORT_COLUMN_DISPLAY, REPORT_COLUMN_SEQ_NO, BEGIN_VALUE, END_VALUEand below columns updating based diff condition with sub queries(see the my 1st post) .

only unique constraint since has pk constraint on 3 columnsconstarints

last question i'm not getting
