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).
  • Authoritative Code Lists: Access the complete and current lists of approved codes and qualifiers used in logistics transactions, such as status codes, discrepancy codes, and unit of issue codes.

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.

  511M G6201 BD Required By For FMS and MAP/GA requirements, use to modify, or in the case of an unmatched modification, to identify the required availability date. For all other uses, it is the revised or required delivery date.
  511M LIN02 AB Assembly
  511M LIN02 BH Finish/Hand Standard Reference Use to identify the fabric of the nonstandard materiel ordered under Federal Supply Schedule.
  511M LIN02 CL Color
  511M LIN02 CN Commodity Name 1. Use to identify the nomenclature of the non-NSN materiel. 2. During the legacy MILSTRIP/DLMS transition, this field will be used to perpetuate/populate the Noun Description of Item on MILSTRIP part-numbered requisition (corresponds to A02/A0B with Identification Code C (rp 70). During this time, a field length greater than 10 positions may be truncated or dropped by the receiving application. 3. Under full DLMS, the field length shall be expanded to conform to this standard which allows 48 positions. DLMS-capable applications should plan to support this expanded field length as a DLMS enhancement. See introductory DLMS 3f.
  511M LIN02 CR Contract Number Use to identify the PID of the Federal Supply Schedule or related instrument when ordering nonstandard materiel. When procurement is authorized under a PID call/order number (F in 9th position), provide the value in the PID field. For Other Transaction (OT) agreements, the type of instrument (9th position of PID) will be 3 for Research OTs or 9 for Prototype and Production OTs. Refer to ADC 1161A or ADC 1420.
  511M LIN02 DR Drawing Revision Number
  511M LIN02 F1 Catalog Number Use to identify the manufacturer's catalog which references the nonstandard materiel. Cite the effective catalog publication date, if applicable, in the 2/G62/080 segment.
  511M LIN02 F2 Technical Order Number 1. During the legacy MILSTRIP/DLMS transition, this field will be used to perpetuate/populate the Technical Order Number/Technical Manual Number identified on MILSTRIP part-numbered requisition (corresponds to AM2/AMB with Identification Code A (rp 70). During this time, a field length greater than 10 positions may be truncated or dropped by the receiving application. 2. Under full DLMS, the field length shall be expanded to conform to this standard which allows 48 positions. DLMS-capable applications should plan to support this expanded field length as a DLMS enhancement. See introductory DLMS 3f.
  511M LIN02 F3 Technical Manual Number
  511M LIN02 F4 Series Identifier Use to identify the manufacturer's series number of the end item.
  511M LIN02 F7 End-Item Description 1. Use to identify the applicable end item which applies to the non-NSN materiel. Description may include the NSN of the end item and/or nomenclature. 2. During the legacy MILSTRIP/DLMS transition, this field will be used to perpetuate/populate the End Item Identification on MILSTRIP part-numbered requisition (corresponds to A02/A0B with Identification Code B (rp 70). During this time, a field length greater than 10 positions may be truncated or dropped by the receiving application. 3. Under full DLMS, the field length shall be expanded to conform to this standard which allows 48 positions. DLMS-capable applications should plan to support this expanded field length as a DLMS enhancement. See introductory DLMS 3f.
  511M LIN02 GS General Specification Number Use to identify a specification number, other than a Military Specification (MILSPEC), associated with the nonstandard materiel.
  511M LIN02 MF Manufacturer Use to identify the manufacturer's make of the applicable end item for the nonstandard materiel.
  511M LIN02 MN Model Number Use to identify the manufacturer's model number of the end item.
  511M LIN02 MS Military Specification (MILSPEC) Number
  511M LIN02 PR Process Number Use to identify a general operating specification which cannot be identified by use of the 2/MEA/105 segment. For example, the MEA use is primarily to identify physical sizes and dimensions of nonstandard materiel. Code PR use is to indicate specifications similar to output rated wattage and horsepower.
  511M LIN02 PT Print or Drawing 1. Use to identify the applicable drawing numbers for the nonstandard materiel. 2. During the legacy MILSTRIP/DLMS transition, this field will be used to perpetuate/populate the Drawing or Specification Number on MILSTRIP part-numbered requisition (corresponds to A02/A0B with Identification Code D (rp 70). During this time, a field length greater than 10 positions may be truncated or dropped by the receiving application. 3. Under full DLMS, the field length shall be expanded to conform to this standard which allows 48 positions. DLMS-capable applications should plan to support this expanded field length as a DLMS enhancement. See introductory DLMS 3f.
