The Target ASN: what breaks first

Target's 856 is smaller than Walmart's and less forgiving in one place: the unit of measure. Ordering in eaches and shipping in cases is the classic first rejection, and it is a data problem that looks like a mapping problem.

Structure

The same HL pattern as any retail ASN, with the levels your guide names:

  • Shipment, then order with PRF, then pack, then item.
  • Carton labels where the guide requires them, one SSCC per carton.
  • Split shipments get their own shipment HL, not a second PRF.

Unit of measure is the trap

Every quantity in the 856 has to be in the unit the PO used. If the 850 ordered 24 EA and the ASN ships one case of 24, the line reads 1 CA and the DC receives 24. Getting that conversion wrong in either direction produces a receipt that cannot be matched.

  • Check the PO's unit of measure before mapping a single line.
  • Keep the case pack in the item master, not in the mapping spreadsheet.
  • A partial case is the exception that needs its own rule.

Labels and routing

The ship-to on the 856 must be the destination on the PO. Target routes to DCs, and a label that scans at the printer but not at the DC is a chargeback rather than a misprint.

The partial shipment

Send a partial line in testing. It is where the line-to-pack relationship breaks: an ASN that assumes every line is a whole pallet passes a clean test and fails the first real short shipment.

Questions

Does Target accept carton-level ASNs?

It requires them for some vendor programmes and not others. The onboarding packet names the level for your vendor number.

How long does Target testing take?

Two to six weeks when item data is ready. The variance is the test queue, not the mapping.
