Overview
The root type of each EDIFACT schema is EDI.
Each schema has EDIFACT, Interchange, and Transmission categories that stem from the EDI root type. For example, the edifd20a schema contains the EDIFACT version D, release 20A.
EDIFACT schemas are organized in the same way that ANSI X12 schemas are organized. If you trade by using both ANSI X12 and EDIFACT, you can easily design a schema to make it a multi-standard schema.
