Management Data Interchangeability and Substitutability



Management Data Interchangeability and Substitutability (MDI&S) is part of the PUB LOG product and represented by the MGMT tab. The MD portion is designed to provide users with supply management data on all National Stock Numbers (NSN) recorded in the Catalog Management Data (CMD) segment of the Federal Logistics Information System (FLIS) database. The I&S portion provides a reference source for determining the interchangeability and/or substitutability of items of supply.
