DESADV Despatch advice message (D18A)
This is the standard EDIFACT D18A spec, with 28 loops and 109 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.
Use the DESADV 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 DESADV files into TSDESADV objects. See ediFabric .NET.
ediFabric Native
Native supports X12 today, and EDIFACT is coming. When it's available, map version D18A to this Native model with set_map to parse DESADV files to JSON from Python, Java, C or C#. See ediFabric Native.
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 DESADV classes in Python, Java, Node.js, Go, Rust or C
The OpenEDI file describes each DESADV as JSON. To work with DESADV data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSDESADV. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
Python: datamodel-code-generator. Node.js: openapi-typescript. Java, Go, Rust and C: OpenAPI Generator.
