856 Series: The Four ASN Hierarchical Structures


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.

856 Series: The Hierarchical Levels of an 856

Hierarchical Levels of an 856The 856 Hierarchy:

A shipment notice is termed an 856 in the electronic data management industry. Understanding the hierarchical levels of an 856 is an important element in helping the sender of products, the supplier, to accurately describe the physical packing configuration of their shipment. It also allows the receiver to better process a transaction by associating a virtual packing configuration of the ASN with a physical shipment. As a result, the receiver can now better prepare resources to more quickly and accurately process the physical shipment. As seen in the diagram on the left, below the hierarchical levels of an 856 are explained.

Starting at the top of the hierarchy is the shipment level. It contains data related shipping information, such as ship from, ship to, bill of loading, shipped date, and more. The next level is the order level, containing data related to the buyer’s original purchase order, such as the purchase order number, purchase order date, and other details. On the third tier, we have the tare level. The tare level contains data related to pallets or master shipping containers. This level is included if pallets or master containers are used on the shipment, and may contain GS1 or UCC-128 carton labels. The pack level is next up, containing data related to the shipping cartons, such as GTIN case codes, quantity shipped and GS1 or UCC-128 carton label. This level may be omitted if there is no need to transmit pack level information. Lastly, there is the item level. This level contains data related item/products information such as UPCs, SKUs, buyers item info, quantity shipped, and more.

These are the 5 levels of the 856 Hierarchy. If you want to learn more about shipment notices, read more about the 856 in our blog section.
