304 Shipping Instructions (006040)

This is the standard X12 006040 spec, with 26 loops and 134 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.

Loading the spec…

The spec as an OpenAPI 3 schema with x-openedi-* extensions, for ediFabric Native, ediFabric Cloud and the EDI Spec Builder. Download OpenEDI (210 KB) Generate classes

The ediFabric .NET template, class TS304. It needs the common segments, composites and codes of X12 006040, one download for every transaction in the version. Download C# (2 KB) Common files (229 KB)

The intermediary model ediFabric Native loads with set_map. Download Native (174 KB)

Use the 304 spec in your code

ediFabric .NET

Add the C# template and its common files to your project, or reference the template NuGet package, and read 304 files into TS304 objects. See ediFabric .NET.

ediFabric Native

Map version 006040 to the Native model with set_map, then parse 304 files to JSON from Python, Java, C or C#. See Convert between EDI and JSON.

OpenEDI

Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.

Generate 304 classes in Python, Java, Node.js, Go, Rust or C

ediFabric Native returns each 304 as JSON, with the property names of the OpenEDI schema. To work with that JSON as typed objects, generate classes from the OpenEDI file in your language and deserialize the JSON into TS304. Serialize the objects back to JSON to build EDI with ediFabric Native. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats, so validate files with ediFabric Native. Read more in Generate a class from OpenEDI.
