DLMS Data Dictionary

The Authoritative Resource for DLMS X12 Data Elements and Codes

This Data Dictionary is the authoritative reference for all data elements used across Defense Logistics Management Standards (DLMS) Implementation Conventions (ICs). It provides standardized definitions and technical specifications for DLMS and its underlying ANSI ASC X12 data structures.

What This Dictionary Provides:

  • Clear Definitions: Find the official business definition and purpose for every data element used in DLMS transactions.
  • Technical Specifications: Get the exact technical format, length, and structure for each element as it appears in an X12 transaction.
  • DLMS to X12 Mapping: Understand exactly how a DLMS business term maps to a specific X12 segment and element (e.g., "Ship-To Address" maps to N1*ST in the 511R transaction).

Who Should Use This Resource:

  • System Developers & Integrators: To correctly build, map, and test DLMS-compliant applications.
  • Logistics & Supply SMEs: To understand the precise meaning and proper use of data in our business processes.
  • Data Analysts & Managers: To ensure data quality, standardization, and interoperability across systems.

Key Implementation Notes:

  • Relationship to Implementation Conventions (ICs): This Data Dictionary is a reference tool that enhances and supports the DLMS Implementation Conventions (ICs); it does not replace them. For proper implementation, users must consult the detailed guidance and business rules contained within the applicable IC.
  • Governing Standards: All data elements are governed by the Accredited Standards Committee X12 (ASC X12) and the policies within DLM 4000.25, Defense Logistics Management Standards (DLMS). The ASC X12 is the governing source for X12, which is an electronic data interchange (EDI) standard.

ELEMENT DLMS NOTE Use only with Asset Reclassification Request Transactions requesting that assets be converted from an NSN to a ‘unit of use’ LSN (1/BIA02/020 code TE with BIA06 code CV), and when the total or partial quantity converted to an LSN by this transaction is also to be protected by JO, or document number. Associated informational KO and COAR may also be provided as applicable. Then use LIN01 codes 1 (total converted qty to be protected) or 2 (partial converted quantity to be protected). Partial quantity protection requires two quantities in the transaction. Also, for Marine Corps only, use when the entire quantity of an NSN or LSN on hand for the requesting owner is to be converted to a unit if use LSN; then use LIN01 code 3. Authorized for DLA industrial activity support agreement only. Refer to ADC 376 and 398. 1 - The total quantity converted from an NSN to a ‘unit of use’ LSN is also to be protected. 2 - A partial quantity converted from an NSN to a ‘unit of use’ LSN is also to be protected. A second iteration of LOOP ID QTY is required so that the partial quantity to be protected can be identified in addition to the total quantity being converted. 3 - Use when conversion request requires the entire quantity of the NSN or LSN on hand for the requesting owner be converted to a ‘unit of use’ LSN. Quantity to be converted is not required and is not specified in the transaction (i.e., LOOP ID QTY is not used).
