Batch formation during picking, also known as batch picking or multi-order picking, is a form of two-stage picking and is used in picking forms such as series-oriented, parallel picking. Requirements from several individual orders are grouped together in batches and the goods are then consolidated by order.

In the following, batch formation during picking will be described on the basis of a two-stage picking process with a batch buffer and sorting machine.

This type of picking includes the following processes in sequence:

1. Forwarding the sales orders calculated by the ERP system to the warehouse management system.
2. Scheduling the picking.
3. Forming pools.
4. Distribution of batches over the course of a day.
5. Processing of rush batches.
6. Optimization of tours.
7. Starting a MDE-guided or goods receipt-introduced tour.
8. Transfer of information to the material flow control system.

Processing of batch formation

Batch picking can be processed in two ways. Either online with a mobile data collection device that handles error quantity processing, zero crossing and work progress reporting via the warehouse management system, or with a goods receipt/issue slip, in which case the warehouse management system receives the messages via a shop floor data collection system.

In any case, a reservation of the tub buffer, also called batch buffer, a check of the fill level, a recording of the batch status and a report of the work progress takes place. If the batch status is complete and the work progress has been carried out, a dynamic batch change usually takes place. After that, all picking bins belonging to the batch are removed from the sorting lines and transported to the sorter. The sorter control then receives all the necessary information.

The following steps are then carried out:

• Sorting by customer order
• Starting the manual packing process
• Printing the delivery note and the label for the CEP service, such as UPS or DHL
• Recording the progress of the work

After that, the orders are transported.

Depending on the operator’s approach, the transport is carried out in accordance with SAIL, a system architecture for intralogistics.
