Using Dsco, you can exchange data such as orders, inventory, order status, shipment and invoice information. The Dsco platform only needs two automated jobs to enable EDI exchange. The first job is an EDI Import job that handles the import of your inventory (846), order status (870), order acknowledgement (855), shipment (856) and invoice (810) data. The second job handles the export of your orders (850). The instructions below provide you with the details you need to ensure proper setup and configuration of your EDI exchange.

Dsco EDI Specifications

Click here to see the full Dsco EDI specifications.

Standard Version

Dsco supports EDI using the 004010VICS  and 005010 versions. 

Please note that only the 850 document is supported in the 005010 version. All other documents, including the 4010 version of the 850, are referenced in the 004010VICS version.

Interchange ID

Dsco uses "DSCO" as the interchange ID with a qualifier of "ZZ".

Data Exchange Protocols


Dsco supports EDI using FTP or SFTP. Dsco recommends using SFTP as it is more secure. 

Every Dsco account includes an FTP/SFTP account that is specific to that account and is not shared with any other. EDI exchange can use the server or you can use your own FTP/SFTP server. 

For those utilizing the standard Dsco FTP/SFTP servers, please be aware of the following:

  1. Transactions coming from you to Dsco need to be placed in the /in directory.
  2. When Dsco processes incoming files, we move the files to the /in/processing directory temporarily, while we process those files, and then we move them to the /in/archive directory once the import has completed.
  3. Transactions being generated by Dsco will be deposited in the /out directory.
  4. Our servers monitor the /out directory. Upon successful download of any file in that directory, we moves the file(s) to the /out/archive folder where you can access them again if necessary. 

Please do not delete the files from the /out directory once you have downloaded them. It is helpful to both parties to have those files available in archive if need be.


For those requiring a higher level of security, Dsco provides access to an AS2 server. The setup and configuration of the AS2 connection is currently manual so please contact our support team at to make a request to utilize AS2. 

Supported Transactions

Dsco supports the following transaction types:

  • 846 Inventory Advice
  • 850 Purchase Order
  • 855 Purchase Order Acknowledgement
  • 856 Advanced Ship Notice (ASN)
  • 870 Order Status (Cancel)
  • 810 Invoice

If you wish to download rich product information, such as product descriptions and images, you can utilize our flat-file exchange using CSV, TAB or Excel formatted files. However, please check with your trading partner as it is possible that they may not be adding that information to Dsco.

ISA Control Numbers

For incoming EDI transactions, Dsco does not require that each transaction have a unique ISA Control Number, but it is best practice, especially in the event that two parties need to research a specific transaction. Dsco does not reject ISA Control Numbers that are not unique. 

For outgoing EDI transactions, Dsco provides an ISA Control Number that is a sequentially incremented number, starting at 000000001.


Dsco utilizes the following defaults for new EDI 850 export jobs:

  • Segment Terminator:              ~      (Decimal Value 126 or HEX 7E)
  • Element Separator:                 *      (Decimal Value 42 or HEX 2A)
  • Sub-element Separator:         >      (Decimal Value 62 or HEX 3E)

For incoming EDI transactions, Dsco automatically detects the above characters as the EDI specification dictates. The Segment Terminator should be the 106th character, the Element Separator should be the 104th character and the Sub-element Separator should be the 105th character.

997 (FA) Acknowledgements

Dsco does not require that you return a 997 for each transaction that we send you, but it is considered best practice to do so and we encourage you to follow best practice. 

When setting up an incoming EDI import job, you have the option of setting the "Generate 997 Flag" option. Selecting this option instructs Dsco to return a 997 for every incoming EDI transaction. If that option is not selected, Dsco will not return the 997. All 997 documents we generate are deposited on our FTP/SFTP within the "/out" directory. Dsco does not currently support the generation of 997 documents that need to be delivered to external destinations.

When processing the incoming EDI transactions, Dsco records the "Sender" and "Receiver" IDs and qualifiers that were provided and switches them in order to generate the 997s. Because Dsco also automatically detects the segment terminator, element separator, sub-element separator and standard version, we use those same characters within the 997s.
