Top EDI 997 (Syntax) & 824 (Business Logic) Rejection Codes & Fixes

Deterministic segment-to-column mapping rules enforced by our client-side X12 engine

Source X12 Segment / Element	Sample Raw Value	Target ERP / CSV Column	Transformation & Validation Logic
997 AK502="4" / AK304="4"	SE01 Segment Count Mismatch	SE01_COUNT_MISMATCH	Declared SE01 count does not equal actual segments from ST to SE. Fixed by recalculating SE01.
997 AK403="7" on TDS / SAC	Illegal Decimal in N2 Element	TDS01 / SAC05_ILLEGAL_DECIMAL	N2 elements cannot contain a period ".". Fixed by multiplying by 100 and rounding to integer.
824 TED01="848" (Out of Balance)	TDS01 != Sum(IT1) ± SAC	TDS01_TOTAL_MISMATCH	Invoice summary total does not match line items. Fixed by recomputing TDS01 & TDS02 in cents.
824 TED01="007" on MAN*GM	Invalid SSCC-18 Check Digit	SSCC18_INVALID_MOD10	20th digit of MAN*GM fails Modulo 10 check. Fixed by recalculating GS1 Modulo 10 check digit.

Critical Chargeback & Import Pitfalls We Prevent

Common EDI mistakes that trigger $250+ retailer fines or accounting balance errors

Manually Editing X12 Files in Notepad Without Recalculating SE01 & CTT

Risk: Endless 997 Rejection Loop

Fixing a business error by adding a REF segment in Notepad breaks SE01, trading an 824 error for a 997 rejection.

Always use EDIParse’s "Auto-Fix All Issues & Re-Serialize X12" button.

Confusing Gateway Syntax Checks (997) with ERP Business Checks (824)

Risk: Missed Chargeback Deadlines

Vendors celebrate a 997 "A" and ignore the 824 "TR" that arrives 2 hours later.

Validate both X12 syntax and retailer companion guide rules in our workbench.

Retransmitting Rejected ASNs After Shipment Arrival

Risk: $250–$500 Late ASN Fine

If your first 856 ASN is rejected due to a bad SSCC-18 check digit, the truck may arrive before you resend.

Pre-validate every 856 in your browser before transmitting to your VAN.
