Audience: Suppliers

As a supplier, you will want to pull orders from CommerceHub's Dsco platform and push inventory, order status, shipment and invoice information to the Dsco platform. 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 Specification

The Dsco platform currently supports two different versions of EDI. Most trading partners should use the 4010 version, linked below. However, some trading partners may require more information, especially on the 850 Purchase Order file. If you require information such as bill-to, tax, gift indicators, and marketing messages to be included with orders, please reference the 5010 850 version.

Standard Version

The Dsco platform 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

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

Note: Both the interchange ID and qualifier can be customized to whatever values the supplier would like to see. This can be done by editing the job settings of an EDI Export job on the Automation ( page.

Data Exchange Protocols


The Dsco platform supports EDI using SFTP. We recommend using SFTP as it is more secure. 

Every Dsco account includes an 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 SFTP server. 


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

  1. Transactions coming from the supplier to the Dsco platform need to be placed in the /in directory.
  2. When the Dsco platform 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 the Dsco platform 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, the Dsco platform 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

The Dsco platform 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 the Dsco platform.

ISA Control Numbers

For incoming EDI transactions, the Dsco platform 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. The Dsco platform does not reject ISA Control Numbers that are not unique. 


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


Although the Dsco platform allows you to configure the following parameters for each individual job, we do utilize the following default settings:

  • 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)
  • Repeat Separator:          <    (Decimal Value 60 or HEX 3C)

You can also choose your own own terminators and separators if you wish. From the table on this website, the Dsco platform supports characters 1-126:

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

997 (FA) Acknowledgements

The Dsco platform 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 the Dsco platform to return a 997 for every incoming EDI transaction. If that option is not selected, the Dsco platform will not return the 997. All 997 documents we generate are deposited on our SFTP within the "/out" directory. The Dsco platform does not currently support the generation of 997 documents that need to be delivered to external destinations.

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