Know how Stockist tracks pallets and totes as Stock Containers, what a Container Type sets, and how stock in a container differs from loose stock.

In short

A Stock Container is a pallet, tote or roll cage with its own barcode. It moves with everything packed in it. Stock is either packed in a container or loose in a location, never both.

Containers and their types

Each container belongs to a Container Type, such as UK Pallet or Euro Pallet. The type sets what every container of that kind shares:

  • its outer size in millimetres, its tare weight and its maximum payload in grams;
  • whether it is hazard compliant, so it can hold hazardous goods;
  • its Mixing Policy, which decides whether one container can hold several products or several clients' stock;
  • its Barcode Rule: a Barcode Prefix such as PAL, then a number, as in PAL-000037.

Each prefix has its own Barcode Sequence, so a barcode is never handed out twice. A type marked as a Pick Container gives pickers totes to pick into.

Containers are your own kit and stay in the building. What you dispatch is a parcel packed at the pack station.

Stock in a container, and loose stock

Stock in a container is Containerized Inventory. It has no location of its own: it is wherever its container is. Stock standing in a location on its own is Loose Inventory.

A location holds loose stock and Stock Containers; each container holds Containerized Inventory, which is wherever its container is. Containers never go inside other containers.

A container sits in one location, or in none until it is first moved. Containers never go inside other containers.

Packing puts loose stock into a container. Unpacking takes it out and leaves it loose in a location. Container Relocation moves a container and everything in it in one step, so nobody moves each product by hand.

Open, closed and inactive

A container's Container Status says whether it is in service, and whether it can take more stock.

A new container is Active and Open. Closing it at the dock makes it Closed. An empty container can be deactivated, and reactivating it makes it Active and Open again.

A container filled at the dock is closed there, which records its weights for its Container Label. A closed container takes no more stock, but you can still move it and unpack it.
