Sending and receiving

Exchange IMPDEF with your trading partners

The specification tells you what a valid IMPDEF 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

IMPDEF in every directory version

A trading partner names both the message and the directory, for example D00A IMPDEF, because the segments differ between versions. Open the one your partner specified.

Frequently asked questions

Which directory version of IMPDEF do I need?

The one your trading partner specifies. IMPDEF is published in 52 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 IMPDEF 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.
