EDI STRUCTURE
How to Read an EDI File
An EDI interchange is a hierarchy of envelopes, transaction sets, segments, elements, and sometimes composite elements.
SHORT ANSWER
Start with the inputs you can verify
An EDI interchange is a hierarchy of envelopes, transaction sets, segments, elements, and sometimes composite elements.
What the estimate means
Start by identifying the standard, version, delimiters, and envelope segments.
Control numbers and declared counts should reconcile across the envelope.
Where estimates go wrong
Do not assume every partner uses the same optional segments or code values; implementation guides define the actual agreement.
Keep the source measurements and assumptions with the result so another person can review or update the estimate later.
A practical workflow
- Preserve the original text.
- Identify delimiters and envelope metadata.
- Validate counts and control numbers before interpreting business content.
