Maintenance Master Data File

 
Under the authority of HQDA ODCS, G-4 (DA G-4), the U.S. Army Materiel Command’s Logistics Data Analysis Center maintains cataloging descriptions and technical information on equipment items in a centralized database called the Army Maintenance Master Data File (MMDF). AR 700-138, Army Logistics Readiness and Sustainability, is the official guidance for policies and procedures as they apply to readiness reporting of Army equipment; and, the identification of readiness-reportable equipment and systems. The MMDF identifies the most current readiness-reportable equipment. The B table reflects readiness reportable items on the MMDF as well as items that have not yet been added to AR 700-138 due to regulation- update time constraints.
The Medical Maintenance Policies and Analysis (M2PA) directorate identifies medical devices and assist the materiel developer in the management medical-device records listed in the MMDF. The goal of the M2PA is to work with materiel developer and ensure that equipment is properly cataloged in accordance with applicable regulations. The M2PA submits equipment record changes to LOGSA/DA G-4 to add, delete, and implement necessary changes to the MMDF based on recommendations to the materiel developer.
LOGSA publishes quarterly MMDF and list of reportable item (tables B-1, 2, 3, and 4, of AR 700-138) updates to the LIW website on a quarterly basis. These are published in the months of January, April, July, and October.
When using the list of reportable items for data analysis, ensure the most current edition is used to assure accurate results. MMDF data can be accessed directly through the LIW portal.
