Mixed UOM picking lets you decide, per product pickface, which units of measure can be picked from that location. Clarus splits each order line into the largest possible blocks — outers, inners, cases, then units — and routes the units of measure you’ve allowed to the pickface, while everything else is picked from racking. This keeps small pickfaces from being drained by large orders and cuts down on repeated replenishments, without you having to enforce every pick through the pickface.

How it works

For each product pickface you set an Allowed Configurations list — any combination of Unit, Case, Inner, and Outer. When an order is processed, Clarus:
  1. Breaks the order quantity into blocks, largest first: Outer → Inner → Case → Unit. Any level that isn’t set up on the product is skipped.
  2. Marks each block Allowed (its unit of measure is in the pickface’s Allowed Configurations) or Restricted (its unit of measure isn’t in the Allowed Configurations).
  3. Combines all Allowed blocks into a single pick task sent to the pickface.
  4. Combines all Restricted blocks into a pick task sent to a racking location as a part pick.
The units of measure come straight from the product’s configuration: Unit uses Output Quantity, and Case, Inner, and Outer use Units Per Case, Units Per Inner, and Units Per Outer. A unit of measure with no value set on the product can’t be allowed on a pickface.

Example

A product is configured as: The pickface has Unit and Case allowed. An order for 55 is split like this: Clarus generates two pick tasks: 50 from racking (a part pick made up of the 2 outers and 1 inner) and 5 from the pickface (1 case).

Set up allowed configurations

1

Check the product configuration

Open the product and confirm the relevant quantities are set: Output Quantity for units, and Units Per Case, Units Per Inner, or Units Per Outer for the packaging levels you want to allow. Only units of measure with a value here can be selected on a pickface.
2

Assign a pickface to the product

On the product’s Pickface panel, add the location or location group you want to pick from. See Set Up a Pickface for the full setup.
3

Set the Allowed Configurations

In the Allowed Configurations column, select the units of measure that should be picked from that pickface. You can set this on a location group to apply it to every location in the group, or click into a location within the group to override it for that location.
If you don’t see the Allowed Configurations column on the pickface grid, add it through the column manager.

Backward compatibility

Turning the feature on doesn’t change existing behaviour on its own. If a pickface has no allowed configurations, Clarus keeps routing picks exactly as before — full pallets from racking and everything else from the pickface.
Mixed UOM picking can’t be combined with Enforce Picking from Pickface. If enforcement is on, Clarus ignores unit-of-measure settings and sends every pick — including full pallets — to the pickface. Enabling enforcement on a product that already has allowed configurations prompts you to confirm, then clears them. See Enforce All Pick Types from a Pickface.
Removing a unit of measure from the product configuration (for example, clearing Units Per Case) removes it from the Allowed Configurations of every pickface for that product. Clarus warns you before saving.

Things to know

  • Full pallets always come from racking. Picking an entire stock record (a full pallet) is never routed to the pickface by this feature.
  • Keep a product’s pickfaces consistent. Assign the same Allowed Configurations to every pickface for a product. Splitting different units of measure across different pickfaces for the same product isn’t supported yet.
  • Pickface cycling still applies. If more than one pickface can fulfil the allowed units of measure, Clarus selects the next location in the rotation, as it does for standard pickface picks.
  • Product data must be accurate. Routing relies on the case, inner, and outer quantities on the product, so keep them up to date.
