Dear Ms. Jacobs:

     Pursuant to Rule 477 (a) promulgated under the Securities Act of 1933, as amended (the “Securities Act”), and our letter to you of September 4, 2003 (File No. 0-22154), Manugistics Group, Inc. (the “Company”) hereby applies for an order granting the immediate withdrawal of the Company’s Registration Statement on Form S-3, File No. 333-100627 (the “Registration Statement”), related to the registration of 69,976 shares (the “Shares”) of the Company’s common stock, $.002 par value per share, for resale by (1) the stockholders of OneRelease.com, Inc., a Delaware corporation (“OneRelease”), and (2) OneRelease.com, LLC, a Delaware limited liability company and affiliate of OneRelease (“OneRelease LLC”).

     The Shares were originally issued, in reliance upon an exemption from registration afforded under Section 4(2) of the Securities Act of 1933, to OneRelease and OneRelease LLC in connection with post-acquisition performance conditions relating to our acquisition on May 17, 2001 of substantially all of the assets of OneRelease and OneRelease LLC. Thereafter, OneRelease transferred the Shares to its stockholders. The Registration Statement related to the resale of the Shares by the OneRelease stockholders and OneRelease LLC.

     The Company is applying for withdrawal of the Registration Statement because all of the shares covered by the Registration Statement are eligible for resale under Rule 144. At September 10, 2003, all but 10,796 of the Shares have been sold in reliance upon and in compliance with the requirements of Rule 144.

     Should you have any questions regarding the foregoing application for withdrawal, please contact Timothy T. Smith, General Counsel, at (301) 255-3460), or, in his absence, Susan E. Pendery, Deputy General Counsel, at (301) 255-5080.
