BEG03 (Purchase Order Number)	4500991288	PONUM / PRF01 / BIG04	Primary legal PO # echoed onto 856 PRF01, 810 BIG04, and 4x6 GS1-128 labels.

Critical Chargeback & Import Pitfalls We Prevent

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

Truncating Long BEG03 PO Numbers in ERP Imports

Risk: 810 BIG04 Mismatch Rejection

If your ERP truncates BEG03 from 12 characters to 8 characters, the 810 Invoice you generate back will fail the buyer’s PO lookup.

Preserve the full alphanumeric BEG03 string across all exports.

Ignoring BEG01="01" (Cancellation) or "05" (Replace)

Risk: Duplicate Shipment

Treating a cancellation or replacement 850 as a brand-new order leads to double-shipping.

Check BEG01 in the left AST inspector before fulfilling.

Not Echoing BEG05 PO Date on 856 PRF04 and 810 BIG03

Risk: Minor EDI Compliance Warning

Many retailers expect the original PO date from BEG05 to be returned in PRF04 and BIG03.

Our 850 turnaround generators copy both BEG03 and BEG05 automatically.

Frequently Asked Technical Questions

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

Why is BEG04 usually empty (two consecutive asterisks **)?

BEG04 is the Release Number, which is only used for Blanket Purchase Orders (BEG02=BK or RL). For standard standalone orders (BEG02=SA), BEG04 is omitted, resulting in BEG*00*SA*4500991288**20261109~.

Where does BEG03 go when generating an 856 ASN or 810 Invoice?

In an EDI 856 ASN, BEG03 maps to PRF01 under the Order (O) HL level. In an EDI 810 Invoice, BEG03 maps to BIG04.
