ASN Hierarchical Structures

The 856 can be an involved EDI document, used to convey shipment, order, pack/pallet and item details. It can be a time-sensitive document and depending on the trading partner’s requirements, must be received before shipment. Hierarchical Levels are used to better define and represent physical shipment. The ASN Hierarchical Structures define the sequence or order in which hierarchical levels will appear within an 856. Here are the four variations to know:

Shipment-Order-Item (S-O-I)

This structure is used for a basic Ship Notice/Manifest and does not include any UCC-128 or GS1 label information.

Shipment – Order – Tare – Pack* – Item (S – O – T – P – I)

This structure is commonly referred to as “pick and pack” structure. It is used
when there is carton labeling (UCC-128 or GS1) and there are multiple products shipped together on a pallet or master container. This structure is used if it is required that labeling be order specific.

Keep in mind, if no Tare (pallet) info is required on the “pick and pack” structure, S-O-P-I is used. If no Pack (carton) info is required on the “pick and pack” structure, S-O-T-I is used. If both pallet and pack info is required on the “pick and pack” structure, S-O-T-P-I is used.

Shipment – Tare* – Order – Item (S – T – O – I)

This structure is used when there is UCC-128 or GS1 labeling and there is no requirement that the labeling be order specific. If there are multiple orders on a pallet or master container, there will be just one label per pallet or master container. There will not be a separate label per order.

Shipment – Order – Item – Tare* (S – O – I – T)

This structure is commonly referred to as the “standard carton” structure. This structure efficiently describes shipment of a single product on one or more pallets or master containers.

ASN Hierarchical Structures are one element of processing 856 EDI documents. Learn more about the Hierarchical Levels of an 856 and other information about ASNs in our EDI blog section.
