Pursuant to Rule 13d-2 promulgated under the Act, this Schedule 13D/A (this
"Amendment No. 4") amends the Schedule 13D filed on October 3, 2007 (the
"Original Schedule 13D"), as amended by the Schedule 13D/A filed on November 6,
2008 ("Amendment No. 1"), the Schedule 13D/A filed on January 5, 2009
("Amendment No. 2") and the Schedule 13D/A filed on April 27, 2009 ("Amendment
No. 3") (the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment
No. 3 together with this Amendment No. 4, are collectively referred to herein as
the "Schedule 13D"). This Amendment No. 4 relates to the common stock, par value
$0.00025 per share (the "Common Stock"), of i2 Technologies, Inc., a Delaware
corporation (the "Issuer"). Unless the context otherwise requires, references
herein to the "Common Stock" are to such common stock of the Issuer.

Item 3.        Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended and restated in its entirety as
follows:

     SAC Capital Associates expended an aggregate of approximately $12,813,199
of its investment capital to purchase the 805,806 shares of Common Stock. Such
shares were effected in the over-the-counter market or in open market purchases
and acquired in the ordinary course of business, and are held by SAC Capital
Associates in a commingled margin account maintained at Goldman Sachs & Co.,
which may extend margin credit to the Reporting Persons as and when required to
open or carry positions in the margin account, subject to applicable federal
margin regulations, stock exchange rules and credit policies. In such instances,
the positions held in the margin account are pledged as collateral security for
the repayment of debit balances in the account. The margin account may from time
to time have debit balances. Since other securities are held in the margin
account, it is not possible to determine the amounts, if any, of margin used to
purchase the shares of Common Stock reported herein.

Item 5.        Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as
follows:

     (a) As of the close of business on July 22, 2009, the Reporting Persons
beneficially own an aggregate of 805,806 shares of Common Stock, representing
approximately 3.7% of the shares of Common Stock outstanding. The percentages
used herein are based upon the 21,986,133 shares of Common Stock reported to be
outstanding as of May 4, 2009 by the Issuer in its Quarterly Report on Form 10-Q
filed with the Securities and Exchange Commission on May 7, 2009.

     SAC Capital Advisors LP, SAC Capital Advisors Inc. and Mr. Cohen own
directly no shares of Common Stock. Pursuant to an investment management
agreement, SAC Capital Advisors LP maintains investment and voting power with
respect to securities held by SAC Capital Associates. SAC Capital Advisors Inc.
is the general partner of SAC Capital Advisors LP. Mr. Cohen controls SAC
Capital Advisors Inc. By reason of the provisions of Rule 13d-3 of the Act, as
amended, each of SAC Capital Advisors LP, SAC Capital Advisors Inc. and Mr.
Cohen may be deemed to own


                               Page 6 of 9 Pages





beneficially 805,806 shares of Common Stock (constituting approximately 3.7% of
the shares of Common Stock outstanding).

     (b) None of the Reporting Persons has sole power to vote or direct the vote
or sole power to dispose or direct the disposition of shares of Common Stock.

          (i) SAC Capital Advisors LP has shared power to vote or direct the
     vote and shared power to dispose or direct the disposition of 805,806
     shares of Common Stock, constituting approximately 3.7% of such class of
     securities;

          (ii) SAC Capital Associates has shared power to vote or direct the
     vote and shared power to dispose or direct the disposition of 805,806
     shares of Common Stock, constituting approximately 3.7% of such class of
     securities;

          (iii) SAC Capital Advisors Inc. has shared power to vote or direct the
     vote and shared power to dispose or direct the disposition of 805,806
     shares of Common Stock, constituting approximately 3.7% of such class of
     securities; and

          (iv) Steven A. Cohen has shared power to vote or direct the vote and
     shared power to dispose or direct the disposition of 805,806 shares of
     Common Stock, constituting approximately 3.7% of such class of securities.

     (c) Information concerning transactions in the shares of Common Stock
effected by the Reporting Persons during the past 60 days is set forth in
Schedule A hereto and is incorporated herein by reference. All of such
transactions were effected in the over-the-counter market or in open market
transactions through various brokerage entities on the NASDAQ Global Select
Market.

     (d) No person other than SAC Capital Advisors LP, SAC Capital Associates,
SAC Capital Advisors Inc. and Steven A. Cohen is known to have the right to
receive or the power to direct the receipt of dividends from, or the proceeds
from the sale of, the shares of Common Stock directly beneficially owned by SAC
Capital Associates.

     (e) The Reporting Persons ceased to be the beneficial owners of more than
five percent (5%) of the shares of Common Stock on July 17, 2009.


Item 6.        Contracts, Arrangements, Understandings or Relationships with
               Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended and restated in its entirety as
follows:

Other than as described herein, there are no contracts, arrangements,
understandings or relationships (legal or otherwise) between the Reporting
Persons and any other person with respect to the securities of the Issuer.


                               Page 7 of 9 Pages





The Reporting Persons may, from time to time, enter into and dispose of
cash-settled equity swaps or other similar derivative transactions with one or
more counterparties that are based upon the value of shares of Common Stock,
which transactions may be significant in amount. The profit, loss and/or return
on such contracts may be wholly or partially dependent on the market value of
the shares of Common Stock, the relative value of shares of Common Stock in
comparison to one or more other financial instruments, indexes or securities, a
basket or group of securities in which shares of Common Stock may be included,
or a combination of any of the foregoing. These contracts do not give the
Reporting Persons direct or indirect voting, investment or dispositive control
over any securities of the Issuer and do not require the counterparties thereto
to acquire, hold, vote or dispose of any securities of the Issuer. As of the
date hereof, an affiliate of the Reporting Persons, S.A.C. MultiQuant Fund, LLC,
currently has short economic exposure to 100 shares of Common Stock.
Accordingly, the Reporting Persons disclaim any beneficial ownership in any
securities that may be referenced in such contracts or that may be held from
time to time by any counterparties to such contracts.

Item 7.        Material to be filed as Exhibits.
