PO1 Segment Elements & Product Qualifier Dictionary

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

Qualifier UP / EN / UK	UP012345678905 / UK10012345678902	UPC-12 / EAN-13 / GTIN-14	UP = 12-digit Consumer UPC; EN = 13-digit European Article Number; UK = 14-digit Case GTIN.

Critical Chargeback & Import Pitfalls We Prevent

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

Hardcoding PO107 as UPC and PO109 as SKU

Risk: Scrambled Order Lines

One retailer sends PO1*...*UP*123*VN*ABC~, while another sends PO1*...*IN*999*UP*123~. Fixed index parsers grab the wrong field.

Our parser steps through PO106+ in pairs of 2 to build a normalized qualifier dictionary.

Returning Partial Qualifiers on 856 LIN and 810 IT1

Risk: 824 Line Match Error

If the buyer sent IN and UP in PO1, omitting IN on your outbound 856 or 810 causes line matching to fail.

Our turnaround engine echoes all PO1 qualifiers onto LIN and IT1.

Missing Internal SKU When Buyer Only Sends IN & UP

Risk: Failed Shopify / QuickBooks Import

Walmart and Target often omit VN (your SKU) and only send their own Item #/DPCI and UPC.

Use our SKU Cross-Reference Drawer to map IN or UP codes to your internal SKU.

Frequently Asked Technical Questions

ANSI X12 specification details, retail companion rules, and ERP import answers

What is the difference between UP and UK in a PO1 segment?

UP is a 12-digit UPC-A barcode printed on the individual retail unit. UK is a 14-digit GTIN-14 (ITF-14) barcode printed on the outer corrugated master case.

What qualifier does Target use for DPCI and Amazon use for ASIN?

Target transmits its 9-digit DPCI (XXX-XX-XXXX) using qualifier "IN" (Buyer’s Item Number). Amazon Vendor Central transmits its 10-character ASIN using qualifier "BP" (Buyer’s Part Number).
