ADC 180 

Revision to Material Release 940R DS to add AIN and BDN 

1. ORIGINATOR: Defense Logistics Agency (DLA) Defense Distribution Center (DDC- J6) 

and DLA-J3731

2. FUNCTIONAL AREA: Primary: Supply

3. REQUESTED CHANGE: 

a. Title: Revision to Material Release 940R DS to add AIN and BDN

b. Description of Change: The change is provided to support the medical and industrial 

kitting community requirements. The basic processes involved in the information exchanges 

covered by this change are consistent with current processes used by the Defense Logistics 

Agency and USAMMA, however, the medium of exchange will be the DLMS ASC X12 

standard transaction set rather than the current DLSS DLA-unique Material Release Orders 

(MRO) A5_ transaction used to requisition medical kits. Under the current unique process, the 

AIN is embedded in the required delivery date (RDD) field, and the BDN is embedded in the 

project code and distribution code fields. Both the AIN and the BDN need to be separated into 

there own individual fields on the 940R to stay consistent with data integrity goals of the DLMS. 

This change provides mapping support for the identified data elements when present in MILS 

MROs prepared by non-DLMS compliant Inventory Control Points (ICPs) for transmission to 

the Distribution Standard System in a post-DLMS migration environment. The BDN and AIN 

do not need to be added to any other DLMS transactions as a result of this effort. When used, 

both the AIN and BDN must be present.

c. Procedures: 

(1) Revise DLMS Supplement for 940R, Materiel Release to include the BDN and AIN.

1. 2/N901/0400 Revise to include qualifier and note to identify the 

BDN. 

77 Work Package 

DLMS Note: 

Use to identify the Build Directive Number for 

medical/surgical component assembly. (A data 

maintenance action was approved in version 5010. The 

approved code/name is BDN – Build 

Directive Number.)

Required information for kitting 

functionality. 

DLMS 650A uses qualifier WO, Work 

Order Number, for identification of the 

BDN, however, WO is already used in 

the 940R to represent a maintenance 

work order number.

2. 2/N901/0400 Revise to include qualifier and note to identify the AIN. 

WF Locally Assigned Control Number 

DLMS Note: Use to identify the 

Assemblage Identification Number (AIN).

Required information for kitting 

functionality. 

DLMS 650A uses qualifier A3, Locally 

Assigned Control Number, for identification 

of the AIN. The same name is used in the 

940R but the qualifier differs because a 

different X12 segment is used (N9 vice LIN).

(2) Update MILSTRIP Appendix 3.12, Materiel Release Order/Follow-Up for Materiel 

Release Order/Lateral Redistribution Order, as indicated in the enclosure. 

(3) Update MILSTRIP front matter, Acronyms and Abbreviations, and Definitions and 

Terms as follows: 

AIN Assemblage Identification Number 

BDN Build Directive Number

ASSEMBLAGE IDENTIFICATION NUMBER. AIN is a 2-position numeric ranging from 

01-20 and is the second level identifier for medical and industrial kits/sets. It is system 

generated at the build manager level based on the number of kits required. 

BUILD DIRECTIVE NUMBER. BDN is a 4-position alphanumeric value used to identify a 

specific build order of a medical/industrial kit. It is system generated at the build manager 

level and serves as the first level identifier. 

(4) Update DAASC conversion maps to map first three positions of the BDN from 940R 

to record positions (rp) 57-59 project code, the fourth position of the four-position BDN from rp 

56, which is the last position of the distribution code field of the DLSS material release order. 

Also, update the DAASC conversion map to map the two-position AIN from the 940R, to rp 62-

63, which are the first two positions of the required delivery date (RDD) on the MILS material 

release order (MRO). 

(5) Mapping from the MILS A5_ to the DLMS is more complex since standard data 

fields are used to contain unique data content. The following specific criteria must be used for 

mapping from MILS to DLSS. Also see Alternatives, below.

• If positions 62-63 are filled and 64 is blank (RDD field); and

• positions 57-59 (Project Code field) is filled; and

• position 56 (last position of the Distribution Code field) is filled; and

• the RIC-From (67-69) is S9M, SMS or B69; 

• Then interpret as an MRO for a Deployable Medical (DPMED) end item and map 

above to the DLMS 940R as BDN and AIN. 

Below is an actual example of a B69 end item MRO at DDHU. The AIN = “01” as found in 62-

63 (first two positions of the RDD). The BDN is “F3XQ” as found in 57-59 (Project Code) and

56 (last position of the Distribution Code).

d. Alternatives: Kitting information may be perpetuated in already implemented 940R 

transactions using MILS data field equivalents. DSS will accept AID/BDN information in either 

set of 940R data elements (Project Code/Distribution Code/Special Requirements Code or 

AIN/BDN). DLMSO Note: This is a temporary situation which may be employed by 
4

USAMMA until these ADC changes can be accomplished. 

4. REASON FOR CHANGE: 

 a. By breaking AIN and BDN out as separate data elements, the source of supply can 

perpetuate to the Distribution Standard System the actual values intended for the project 

code, distribution code and RDD. This is important because there could easily be overlap 

and the project code and RDD values are needed for printing on the package label. The 

perpetuated distribution code ensures all parties receive shipment status. 

b. This change is consistent with DLMS goals of separating dual use fields into unique 

fields. Currently the part of the BDN and AIN are hidden as described above. This change 

supports desired DoD goals for data integrity. 

c. Requisitioning by AIN/BDN is applicable in a very limited environment and will require 

separate DLMS changes focused on the applicable processes to develop the necessary 

infrastructure. This change is intended to restructure the DLMS transaction as a foundation for 

future information exchange based on AIN and BDN as a planning tool to improve DLA kitting 

planning and requisitioning. 

d. By breaking these data elements out, the ability to requisition specific kits may some day 

become possible. The biggest benefit would be to industrial and medical kitting requisitioners. 

Industrial and medical kits are stored in a way that the stock selector could pull specific kits. 

Items not stored this way will be picked as usual until a change in DSS is made to accommodate 

for all kits stored in DLA warehouses. That would require a separate action. In the mean time, 

there is no guarantee that ordering by BDN and AIN will get you a specific kit outside of the 

medical and industrial kitting arena. Kits are not serially managed. 

These data elements are necessary to the kitting/assembly process. The AIN/BDN combination 

is used by the assembly function for internal control of component control numbers being 

applied to a particular kit or assembly. In the case of both medical and industrial kitting, the 

assembly function can pre-plan a build down to a container and then control pick down to that 

container. 

5. ADVANTAGES AND DISADVANTAGES: 

a. Advantages: The change supports DLMS implementation and medical and industrial 

kitting requisitioning from DLA distribution depots.

b. Disadvantages: None known.
