About DAAS

The DAAS primary business is the accurate routing of electronic logistics requisitions between various federal activities. The DAAS eB hub currently employ's the Global Exchange (GEX) software and the Mercator translator.

DAAS has been operating in the eB domain for over 30 years, concentrating primarily on military standard transactions. Since 1993, DLA DAAS has been operating an eB hub of primarily X12-based EDI transactions. In terms of transaction volume (over 10 million every week), the DAAS eB hub is the largest in DoD, providing a single communications pathway to many Value-Added Networks (VANS), and the private sector trading partners served by those VANS. The DAAS Hub handles all of the details involved in routing and communicating with VANS, freeing DLA buying community to concentrate on electronic business applications. Each VAN offers different communications options and requires different access procedures, which creates extra work for electronic commerce projects that need to trade with many partners. The VANS primarily send/receive X12 data files with DLA DAAS, via a secure FTP protocol

The DAAS EB hubs process over two million eB transactions every week. Electronic Business Translation/Mapping Services DAAS offers standard mapping based upon the DLMS standards in X12 or XML (MILS to X12, X12 to MILS, MILS to XML, XML to MILS, X12 to XML, XML to X12). The Implementation Conventions (IC) are available at: DAAS also offers custom mapping for other types of formats. Our fee for doing mapping is based upon an hourly rate of per hour. DAAS estimates the number of hours needed to do the work and charges accordingly. Normally this is a one-time fee, unless major changes or updates to the maps are necessary. Map costs run somewhere between $5,000 and $10,000.   

VAN/HUB/GATEWAY Services DAAS provides VAN services to federal eB projects for the routing of transactions between DOD customers and some of their Prime Vendor Partners. This means DAAS serves as the central distribution center for the routing of transactions to external sites, Prime Vendors, and internal VAN mailboxes for pickup by Prime Vendors.

DAAS/EDI routes transactions to external commercial VANS, such as AT&T/Easylink, who then distribute the transactions to their customers/vendors. DAAS' gateway accepts communication protocols, SFTP, HTTPS, and MQ from both government and contractor customers.

What DAAS Offers

 Electronic Data Interchange (EDI)

Electronic Data Interchange (EDI) is the exchange of routine business transactions in a computer processible format, covering such traditional applications as inquiries, planning, purchasing, acknowledgements, pricing, order status, scheduling, test results, shipping and receiving, invoices, payments and financial reporting.  Additional standards cover interchange of data relating to security, administrative data, trading partner information, specifications, contracts, production data, and distribution and sales activities. 

Through the use of the Accredited Standards Committee (ASC) X12, electronic data interchange is based on interdependency.  This way, internally or externally developed software and public-access communications vendors, all sizes of firms and institutions using intelligent computational devices may benefit from the use of the standard.  Thereby, all institutions reap the efficiencies of a common interchange language, rather than experience the difficulties of an increase of methods and procedures that could occur if each institution were to impose its own format on every institution with which it does business.

 EDI Dial-In and File Naming Conventions

Exchanging_EDI_data_with_Transaction Services_over_the Exchanging eB data with Transaction Services over the internet

The DAAS GEX EDI supports SFTP, HTTPS, SMTP/MIME, and MQ to transport X12 transmission files over the internet and the NIPRNET. DAAS Data Delivery via a secured protocol and implementation of Firewalls throughout DoD, will require the customers assistance.

If a customer requires an SFTP connection using the SFTP/SSH protocol, then this protocol is similar to FTP, but it uses encryption to secure the connection. The technical details are discussed: in this document

Additional information about this protocol and implementations can be found at: OpenSSH home page

This page describes the OpenSSH project, which provides an Open-Source implementation of the protocol. For commercial vendors that support the protocol there is a section on that page labeled 'Alternatives.'

DLA DAAS requires that Public Key Authentication (PKA) be performed when DLA DAAS initiates the connection to the customers SSH/SFTP server. Password authentication is possible when your connection is made with a DLA DAAS server but is not preferred.

You are referred to this discussion of Public Key Authentication for more information: Public Key Authentication

DAAS has several SFTP IP addresses. While it is not required, programming one IP address as a primary and the other IP address as a backup should be considered to prevent loss of connectivity. We make every effort to ensure that we keep one of the two machines up at all times, but if you program a single address, you'll be unable to send in files while that machine is down for maintenance.

Network Addresses for FTP

DAAS has several IP addresses that you may use for FTP destinations. While it is not required, you should consider programming one IP address as a primary and the other IP address as a backup. We make every effort to ensure that we keep one of the two machines up at all times. If you program a single address, you'll be unable to send in files while that machine is down for maintenance.

We prefer that you send your data to the Dayton, OH hub unless we have instructed you to do otherwise.

SMTP Mail Destination

DAAS has flexible support for transmission and receipt of eB data via SMTP. The data can be in the body of the message or as a MIME attachment.

If you are interested in exchanging eB data via SMTP, please request sample transmissions by email to

AS/1 is not currently supported.

HTTPS Transfers

DAAS supports a form-based interface for sending and receiving files via HTTPS. The options here varied and are currently the subject of ongoing development and testing.

We’ve found that it is fairly easy to interface using HTTPS with only a trivial CGI program.

An interactive file-based dialog is available via HTTPS for uploading to DAAS.

DAAS currently requires specific firewall rules to be applied locally to allow inbound HTTPS transmissions to our systems. Please contact for more information about this mode of communication.

AS/2 is not currently supported, but DAAS is looking into this increasingly popular mode of communication. If you have a requirement for AS/2, please contact us at

Pushing/Pulling with FTP

We support your pulling data from our servers or pushing data to our servers. By push we mean that for files coming to DAAS, the sending site will run its FTP client, log on with a username and password provided by DAAS and initiate placing data. By pull we mean that the receiving site will run its FTP client, log on with a username and password and initiate a retrieval.

We also support pulling data from your server or pushing data to your server. IfDAASs is initiating the transmission, then DAAS will need to be provided with a user ID and password on the host at your site.

If you wish to pull your files from DAAS, you should do so with an FTP GET or MGET command. After you pull the files, it is your responsibility to make sure that you have received them completely and then delete them. DAAS cannot delete EDI files for users who pull.

Make sure that you only pull files whose names begin with the letter "D" followed by your site code. That way, you will not pull-down files that may reside in your directory for administrative or other purposes. In the following example, suppose that your site code is MGSC:

 FTP> mget DMGSC*.* 
 After checking that your received everything. 
 FTP> mdel DMGSC*.*
 FTP> quit 

Our DEBX system, where all new setups are performed, guarantees that no new files can come into the directory after you login, thus ensuring that the above procedure does not delete any files that have arrived after the mget and before the mdel command.

File Naming Conventions

DAAS prefers that you uniquely name every file that is sent to us. Likewise, DAAS' file transfer software will uniquely name files it sends to your site.

Files that you send to us should be named as follows:

I.jjj where is the 4-letter site code that we will assign to you. nnn is an arbitrary sequence number and jjj is the julian date.
Example: IQBAX001.109

A technique most of our customers use is to transfer in their file with a "Z" as the first letter. After the transfer has successfully completed, the file is renamed, changing the first letter to "I". This way, we don't attempt to process a partial file that is doomed to fail.


 SFTP> put our file ZQWER348.255
 SFTP> rename ZQWER348.255 IQWER348.255

You can make the sequence numbers longer or shorter as you wish or use alphanumeric sequence numbers. The primary requirement is that the file names begin with the letter "I". File names are case-sensitive on our GEX system. We can support file names that begin with a lower case 'i' if required.

We prefer this naming convention because it identifies the file as yours and contains elements to ensure a unique name. The better the name, the easier it is to find a file when a problem occurs.

Other file naming conventions can be supported for special interfacing requirements, such as to MVS or AS/400 systems.

The files we send to you will be named as follows:

Dnnn.jjj where is your username on the DAAS computer, nnn is a sequence number which we generate, and jjj is the julian date. Generally, the DAAS FTP client software generates uppercase file names on UNIX systems.

Example: DQXYZ002.109

Other file naming conventions for transmission can be supported for special interfacing requirements, such as data set names. ‘Site’ commands custom to your application can also be accommodated

Frequently Asked Questions

 Are public requests for quote (RFQ) available from Transaction Services?

Yes. RFQ's from the Navy Electronic Commerce Office (NECO) are available on request.

 Does Transaction Services do translation?

Transaction Services has translation & mapping software for most eB standards, including all versions of X12.

Transaction Services provides translation services for those customers who desire it. If the requirement for significant resources must be applied to a mapping project, then it is based on standard hourly rates.

 Does Transaction Services provide services to DLA only?

No. Transaction Services' eB customers include the Defense Logistics Agency, all of the Military Services/Agencies, the Administrative Office of the US Courts, and others. If you're interested in obtaining services from Transaction Services for your federal or state government activity, contact for more information.

 Does Transaction Services require any particular separators or terminators?

You can use anything that is supported by the standards and is acceptable to your trading partner(s) and the VANs. Transaction Services imposes no restrictions.

 Does Transaction Services support encryption?

Yes. Transaction Services will encrypt or decrypt data for VANs and/or DoD/DLAl clients. We currently support PGP (Pretty Good Privacy) the most widely used public key encryption scheme currently available--and the proprietary Compress encryption software.  Transaction Services, also, supports HTTPS for delivery of transactions.

 How does our VAN establish a relationship with Transaction Services and DoD/DLA?

Contact the eB Program Manager at  Be prepared to provide information regarding the communication regimes that you support, and instructions on how to process connections.

If you expect to exchange files with Transaction Services using FTP, be prepared to provide a username, password and IP address that we can program into our file transfer software.

Also, please read our pages on Host Systems and file naming conventions

 How long does it take Transaction Services to process an interchange?

The median time required to move an interchange through the system and deliver to a VAN is 15 minutes. The median time required to deliver an interchange to a mailbox on our own VAN is 5 minutes.

We are connected to many VANs via dedicated circuits. Median delivery times to these VANs are about 10 minutes.

For VANs we reach via dial-up BISYNC, the normal transfer time for an interchange is closer to 20 minutes.  Transaction Services is currently converting all BISYNC customers to FTP protocol for better and faster communications.

 We're a vendor and want to do business with DoD/DLA?  How do we get started?

Transaction Services is a data communications center for the buying centers of DoD/DLA. In essence, we perform like the post office median in routing transactions to the proper destination(s). Potential new customers will need to contact the various DoD/DLA procurement centers that purchase goods and services to establish a business relationship at the supply centers as an eB trading partner. From our website see the url link for EDI Defense Logistics Supply Centers

 What eB standards and versions are supported by Transaction Services?

The eB standards that Transaction Services can process include X12, XML, UDF's and IDOC. Currently, most Transaction Services eB customers use X12. All X12 versions from 2002 are supported.

 What forms of communication does Transaction Services support?
  • SFTP across a dedicated circuit.
  • HTTPS (Hypertext Transfer Protocol Secure) provides authentication of the web site and server providing bidirectional encryption communications between client and server.
  • SMTP (MIME) across the NIPRNET/INTERNET and dedicated circuits.
 What kind of computer hardware and software are you running?

The Transaction Services eB hubs run on HP N-Class platforms connected to a high-speed Storage Area Network (SAN). The Defense Global Exchange (GEX) Hub software runs on a UNIX operating system and utilizes Mercator as the translation/mapping engine,

 What X12 transaction sets will you process?

All ASC X12 approved transaction sets.  Transactions must conform to X12 syntax and contain all required elements.
