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 1. Use one of codes 08, AW, BL, BM, IZ, K2, K3, ZH, or WY with REF01 code TG (TCN) to identify a secondary transportation number. Where applicable, two secondary transportation numbers may be provided, e.g. for CAV shipment status the carrier tracking number (PRO) may be identified in REF04-01 and the bill of lading number (commercial or Government) may be identified in REF04-02. 2. For CAV shipment status, must use to identify the procurement document which authorized the commercial contractor to repair and ship GFP into DoD inventories. Use with contractor-assigned shipment number (REF01 Code SI). 3. Under ADC 1014, GFP contract data is transitioned from the REF segment to the GF Segment. Delayed implementation is authorized.
CODE CT
X12 CODE NAME Contract Number
GENERAL CODE DEFINITION A standard unique identification of a DoD procurement contract (contract number) that specifically differentiates one contract from all other contracts
CODE DLMS NOTE 1. Must use for CAV shipment status, to identify the procurement instrument identifier (PIID) authorizing repair/return of GFP. Use the legacy procurement instrument identification number (PIIN) pending transition to the PIID. When procurement is authorized under a PIID call/order number (F in 9th position), provide the value in the PIID field. For Other Transaction (OT) agreements, the type of instrument (9th position of PIID) will be a 3 for Research OTs or 9 for Prototype and Production OTs. Refer to ADC 1161A or ADC 1420. 2. Under ADC 1014, GFP contract information is transitioned from the REF segment to the GF Segment. Delayed implementation is authorized. 3. Authorized DLMS enhancement; see introductory DLMS 2a.
