How to Pick LPNs for Wholesale Orders

In wholesale picking flows, ShipHero allows users to pick inventory assigned to License Plate Numbers (LPNs). This article covers the process of picking LPNs in manual and mobile workflows and the expected system outcomes.

LPN assignment is configured during the creation of the Picking Plan. For more information, see How to Create a Picking Plan for a Wholesale Order.

Picking LPNs in the Manual Picking Workflow

Important

LPNs are assigned when the Picking Plan is created. Users cannot manually edit or swap assigned LPNs while manually picking line items after the plan is generated.

When using the manual picking workflow (picking from paper), the location and LPN are displayed on the Picking List.

  • If the total inventory assigned to the LPN is required, the line item displays the PICK ENTIRE LPN badge.
  • If only a portion of the LPN is required, no badge is displayed. The picker must manually pick the specific quantity listed in the Required column.

After items are physically moved, click Transfer Units to Staging.

  • Line items with the PICK ENTIRE LPN badge move the complete LPN record to the staging location.
  • Partial picks from an LPN remove the specific quantity from the LPN in the source location and transfer those units to the staging location. The original LPN remains in its source location.

Picking LPNs in Mobile Picking Workflows

The mobile interface uses direct LPN scanning to validate requirements in real time. When a picker scans an LPN, the system validates the location, SKU, and lot to ensure it matches the order requirements.

Important

Fully picking mixed LPNs (LPNs containing multiple SKUs) is not supported.

Example: If LPN-1 has 500 of SKU1 and 500 of SKU2, and an order needs exactly those amounts, you cannot move LPN-1 to staging as a unit. You must pick both SKUs from the LPN individually. The result: LPN-1 is marked as Used, and the stock moves to the staging location as loose items rather than a tracked LPN.

Mobile Execution Methods

Method Picker Action
Direct Scan Scan the LPN barcode. The system identifies the item, lot, and location in one step.
Traditional Flow Scan the location barcode first. The system then prompts the user to scan an LPN or item.

Smart Logic for Item Scanning

If a picker scans an item barcode instead of an LPN barcode at a location, the system applies the following logic:

  • If loose inventory exists: The system directs the picker to pick the non-LPN items from the location first to clear loose stock.
  • If no loose inventory exists: The system prompts the picker to scan the specific LPN from which they are retrieving the item to maintain container integrity. Once the LPN is scanned, the mobile app displays "Picking from LPN."

LPN Transitions to the Packing Layout

The system updates the Packing Layout based on how the LPN was processed during the pick.

  • Full LPN Pick: If the quantity of a SKU within an LPN meets or exceeds the required amount on the wholesale order, the system processes the full LPN automatically. Inventory remains assigned to the LPN and the entire LPN moves from the source location to the staging location, reflected in the Packing Layout.
  • Partial LPN Pick: If the quantity of a scanned LPN exceeds the required amount on the wholesale order, the user is instructed to scan or enter the quantity they are removing from the LPN.

Mobile Picking & Packing only: If a partial quantity is picked, the system directs the user to scan the items into a new LPN. This new LPN will then appear in the Packing Layout.

Packing Layout Views

LPN picks are visualized in the Packing Layout as follows:

  • Pallet 1: Fully picked pallet LPN.
  • Pallet 2: Fully picked pallet LPN containing nested box LPNs.
  • Pallet 3: New LPN created from partially picked inventory.
