When an order requires only part of a pallet, the remaining goods must stay identifiable, countable, and available for the correct next operation. Automated forklift workflows need to account for both the removed quantity and the physical pallet that remains.
Full-pallet movements are relatively straightforward: the system assigns a pallet to a task, the AGV forklift transports it, and the warehouse records its new location. Partial picking introduces another layer of complexity because the pallet's quantity and possibly its physical configuration change during the operation.
A pallet may be moved from storage to a picking station, have several cartons removed, and then require transportation to another location. If the remaining quantity is not recorded correctly, the warehouse may allocate stock that is no longer physically present.
This guide covers the process controls needed to handle partially picked pallets in warehouses using AGV forklifts.
A partially picked pallet is not simply a pallet with fewer cartons. Its remaining inventory must be represented accurately in the warehouse system.
Before implementing the workflow, define how the warehouse identifies a pallet after picking. The original pallet ID may remain unchanged, while its quantity, status, and storage eligibility are updated. If the pallet is split into multiple handling units, the system must also establish the relationship between the original unit and the resulting units.
Document the following information:
Original pallet ID and product identity.
Original quantity and unit of measure.
Quantity removed during picking.
Confirmed remaining quantity.
Current physical location and handling status.
Whether the remaining pallet can return to normal storage.
The quantity should be confirmed at a defined point in the picking process. Depending on the warehouse design, this may occur at a picking station, a weighing position, or an operator verification point.
Do not allow the AGV forklift to transport a pallet based only on an assumed remaining quantity. The warehouse system should receive a confirmed result before the pallet is assigned to its next destination.
For operations involving cartons or cases, define the unit of measure carefully. A product quantity recorded in individual pieces must not be confused with the number of cartons or layers remaining on the pallet.
If a discrepancy is detected, place the pallet into a controlled verification process rather than automatically updating the inventory to the expected quantity.
Removing goods may change the pallet's weight distribution, height, stability, or load profile. A pallet that was suitable for storage before picking may no longer meet the same handling conditions afterward.
Establish clear criteria for deciding whether a partially picked pallet can be transported and stored by an AGV forklift.
The remaining load is stable and properly secured.
The pallet base remains suitable for the fork arrangement.
The remaining load dimensions meet the equipment's handling limits.
The weight remains within the selected vehicle's rated capacity at the required lift height.
The pallet does not contain loose items that could fall during transport.
Where the remaining load does not meet the warehouse's automated handling criteria, route it to an approved repacking or manual handling position.
After picking, the remaining pallet may need to return to its original storage address, move to a dedicated partial-pallet area, or be transferred to another approved location.
The destination rule should consider inventory quantity, pallet condition, storage restrictions, and future picking requirements. A partially picked pallet should not be returned to a location whose storage rules assume full-pallet quantities or a different handling configuration.
For high-bay warehouses, confirm that the remaining load is suitable for the target rack position and the selected forklift's operating range. If the system cannot verify a valid destination, use a designated holding area with clear inventory status.
The warehouse management system (WMS) should preserve a traceable link between the original pallet, the picked quantity, and the remaining inventory. This is especially important when the operation creates new pallet IDs or splits the original load into multiple handling units.
Define which system owns each transaction. The picking process may confirm the quantity change, while the robot control system (RCS) manages the physical transport. The final inventory location should only be updated after the required movement confirmation is received.
Useful transaction information includes:
Original and resulting handling-unit identifiers.
Picking task reference and completion status.
Confirmed quantity before and after picking.
Transport task identifier and destination.
Final location confirmation and transaction timestamp.
Partially picked pallets can create allocation problems when the warehouse system treats all pallets of the same SKU as equivalent. In reality, the remaining quantity, batch, customer ownership, or product condition may differ.
Allocation rules should evaluate the actual inventory attributes and handling status. A pallet under quantity verification, repacking, or quality review should not be selected as ordinary available stock.
Where the warehouse operates multiple picking processes, define which processes can consume partially picked pallets and which require full handling units. This prevents the automation system from repeatedly sending unsuitable pallets to a picking station.
Pick part of a pallet and confirm the remaining quantity.
Verify that the original pallet ID remains correctly linked to the inventory record.
Test a pallet whose remaining load is no longer suitable for automated transport.
Test a destination that cannot accept the remaining pallet.
Verify that restricted stock cannot be allocated to another order.
Test the creation of new handling-unit IDs after pallet splitting.
Interrupt a movement and verify that the physical location is reconciled.
Confirm that the final quantity and location match the physical pallet.
Key checkpoint: A partially picked pallet must be treated as a changed inventory unit. Confirm its quantity, physical condition, and storage eligibility before releasing the next AGV movement.
Can the WMS update remaining quantities at the picking station?
How are original and newly created pallet IDs related?
Can the system distinguish full pallets from partial pallets?
How are unstable or non-standard loads prevented from entering automated storage?
Can destination rules consider remaining quantity and pallet condition?
How are discrepancies handled before a pallet becomes available again?
Ask the AGV supplier to demonstrate these workflows using the actual pallet types and picking process planned for the warehouse. A successful transport demonstration alone does not prove that partial-pallet inventory is controlled correctly.
Automating partially picked pallets requires coordination between inventory records, picking confirmation, load suitability, and AGV transport. When these conditions are defined clearly, warehouses can move remaining goods without creating uncertainty about quantities or storage eligibility.
