Sending and receiving
Exchange SSIMOD with your trading partners
The specification tells you what a valid SSIMOD looks like. Sending and receiving one means mapping it to the system that holds the data, agreeing the format with each partner, and handling the messages that come back when something is rejected. XEDI does the mapping, validation and transport.
Specifications
SSIMOD in every directory version
A trading partner names both the message and the directory, for example D00A SSIMOD, because the segments differ between versions. Open the one your partner specified.

Frequently asked questions
What is the SSIMOD message?
System synchronization modification. It is one of the UN/EDIFACT message types, identified by the six-letter name SSIMOD in every directory version that publishes it.
Which directory version of SSIMOD do I need?
The one your trading partner specifies. SSIMOD is published in 58 directory versions and the segment detail differs between them, so a mapping built for one version is not automatically valid for another.
How do I send a SSIMOD message?
Map the data from the system that holds it into the segment structure the agreed directory version defines, then transport it by the route the partner uses, commonly AS2 or SFTP. XEDI handles the mapping, validation and transport, and surfaces the acknowledgements and errors that come back.
