What is SignalEDI?
Generalized public guidance
These pages explain error patterns without publishing customer payloads, PHI, support tickets, or tenant transaction logs. Use them to identify the likely segment, source-system field, and validation rule before retrying a partner exchange.
High-intent fixes
Understand a missing ship date on an EDI 856 advance ship notice: what it means, where it appears, how to fix it, and how SignalEDI validates ASNs before partner testing.
Read fix steps →
General validation errorsLearn why an invalid DTM date/time reference segment fails EDI validation, how to correct qualifiers and date formats, and how to prevent repeat DTM errors.
Read fix steps →
General validation errorsUnderstand invalid GLN errors in EDI trading-partner documents: where GLNs appear, why partner validators reject them, and how to correct location identifiers.
Read fix steps →
810 invoice errorsLearn why an EDI 810 invoice is rejected for a duplicate invoice number, how to correct BIG02 and ERP invoice sequencing, and how to prevent repeat duplicate invoices.
Read fix steps →
General validation errorsUnderstand invalid purchase-order number errors across EDI 850, 856, and 810 workflows, including PO reference fixes and prevention steps.

The ASN does not carry the shipment date a retailer or warehouse uses to match the ship notice to pickup, routing, receiving, and appointment windows.
The ASN's hierarchical loops do not follow the structure the partner expects, such as shipment to order to pack to item.

The buyer has already received an invoice with the same invoice number for the supplier, purchase order, or billing relationship.
The invoice does not include the monetary total the buyer expects in the TDS segment, or the segment is present without the required amount.

The interchange trailer does not reference the same control number declared in the interchange header, so the envelope cannot be reconciled safely.
The transaction trailer declares a segment count that does not match the actual number of segments from ST through SE.

A DTM segment has a missing qualifier, an invalid date value, or a date/time placement that does not match the partner's implementation guide.
A Global Location Number used for a ship-to, bill-to, supplier, or facility identifier is missing, malformed, or not enrolled for the trading-partner relationship.
A purchase-order reference is missing, malformed, or does not match the buyer's original order in a downstream ASN, invoice, or acknowledgement.
A segment required by the X12 transaction set or partner implementation guide is absent from the file or appears in the wrong loop.
Sandbox first
A retry does not fix a bad segment, stale control number, or missing business field. Validate the file, confirm the partner rule, then resend only when the correction is clear.
EDI troubleshooting
Error guides, validators, document references, and setup paths for correcting EDI failures.
It is a public, generalized reference for common X12 and partner-validation errors. It explains likely causes, correction steps, prevention steps, and related document guides without using customer files or tenant data.
Yes. Use the public EDI validator for synthetic or approved samples. Do not paste PHI, patient data, credentials, secrets, or confidential customer payloads into public tools.
They are generalized patterns. Trading partners can add stricter requirements, so confirm the current implementation guide for the exact partner lane.
Open a fix guide above, run the public validator on a synthetic sample, then retry only when the correction is clear.
