Pursuant to Rule 13d-2 promulgated under the Act, this Schedule 13D/A (this
"Amendment No. 1") amends the Schedule 13D filed on October 3, 2007 (the
"Original Schedule 13D" and, together with this Amendment No. 1, are
collectively referred to herein as the "Schedule 13D"). This Amendment No. 1
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 Schedule 13D is hereby amended and restated in its entirety as
follows:

     SAC Capital Associates expended an aggregate of approximately $21,051,659
of its investment capital to purchase the 1,355,806 shares of Common Stock. Such
shares were effected 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 Schedule 13D is hereby amended and restated in its entirety as
follows:

     (a) As of the close of business on November 5, 2008, the Reporting Persons
beneficially own an aggregate of 1,355,806 shares of Common Stock, representing
approximately 6.3% of the shares of Common Stock outstanding. The percentages
used herein are based upon the 21,567,303 shares of Common Stock reported to be
outstanding as of August 1, 2008 by the Issuer in its Quarterly Report on Form
10-Q filed with the Securities and Exchange Commission on August 7, 2008.

     SAC Capital Advisors, SAC Capital Management, and Mr. Cohen own directly no
shares of Common Stock. Pursuant to investment management agreements, each of
SAC Capital Advisors and SAC Capital Management share all investment and voting
power with respect to securities held by SAC Capital Associates. Mr. Cohen,
through one or more intermediary holding companies, controls each of SAC Capital
Advisors and SAC Capital Management. By reason of the provisions of Rule 13d-3
of the Act, as amended, each of SAC Capital Advisors, SAC Capital Management,
and Mr. Cohen may be deemed to own beneficially 1,355,806 shares of Common Stock
(constituting approximately 6.3% 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.

                                     6 of 8


          (i) SAC Capital Advisors has shared power to vote or direct the vote
     and shared power to dispose or direct the disposition of 1,355,806 shares
     of Common Stock, constituting approximately 6.3% of such class of
     securities;

          (ii) SAC Capital Management has shared power to vote or direct the
     vote and shared power to dispose or direct the disposition of 1,355,806
     shares of Common Stock, constituting approximately 6.3% of such class of
     securities;

          (iii) SAC Capital Associates has shared power to vote or direct the
     vote and shared power to dispose or direct the disposition of 1,355,806
     shares of Common Stock, constituting approximately 6.3% 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 1,355,806 shares of
     Common Stock, constituting approximately 6.3% 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 open market purchases through various brokerage
entities on The Nasdaq Stock Market.

     (d) No person other than SAC Capital Associates, SAC Capital Advisors, SAC
Capital Management 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) Not applicable.

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

Item 6 of 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.

     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

                                     7 of 8


foregoing. In addition to the shares of Common Stock reported herein by the
Reporting Persons, through such contracts S.A.C. MultiQuant Fund, LLC, an
affiliate of the Reporting Persons, has short economic exposure to 29,548 shares
of Common Stock. 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. 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.
