Multi-Order Picking (MOP)
Order-pure, parallel picking of multiple orders in a shared run with separate compartments/containers per order.
Purpose
- Reduce travel and pick times by processing multiple orders in parallel in a single picking run.
- Unlike series picking, the order reference is maintained throughout the entire picking process — each order is picked order-purely into a dedicated compartment of the MOP cart.
- Particularly suitable for many small orders with short pick lists.
Prerequisites
- MOP batch number series stored in SIEVERS WMS Setup
- Order types activated for MOP batch creation
- MOP batch creation strategy created
- At least one MOP cart with configured compartments available
- Warehouse shipments released
- Optional: Automatic run of task Create MOP Batch in job queue
Input | Output
| Input | Output |
|---|---|
| Released warehouse shipments matching the MOP strategy criteria | Picking document of type MOP; order-purely filled MOP cart compartments |
Setup
- SWMS Feature Setup: activate Multi Order Picking.
- Order Type: enable MOP Batch Creation (Series Creation must remain disabled).
- MOP Batch Creation Strategy: define criteria (location, max. orders, max. lines, max. weight, max. volume).
- MOP Cart: create an industrial truck with MOP compartments; the number of compartments determines the maximum orders per batch.
Roles
- Picker: Carries out MOP picking on the MDE device (A4 Picking).
- Warehouse planner: Controls MOP batch creation strategy, release, and prioritization.
- Packaging: Takes over order-pure compartments, creates SSCCs, completes the process.
Documents
- Source documents: sales orders, transfers, etc.
- MOP batch: consolidation of multiple orders (visible in MOP Monitor).
- Picking document of type MOP picking.
- Warehouse shipment documents: final documentation per order/SSCC.
Process Flow
Phase 1: Create MOP Batch
Order prerequisites: Status Released, first loading date within the lead time horizon, filter criteria of the strategy met.
Three options for creation:
- Via search (Ctrl+Q): → Create MOP Batch → optionally select strategy → OK
- Via warehouse shipment planning: → Create MOP Batch → optionally select strategy → OK
- Automatically: Set up a job queue entry with codeunit Create MOP Batch and activate it.
Hinweis
Newly created batches receive status 0-Created. If the Min. number of orders is not reached, the batch remains in this status and must be released manually or discarded.
Phase 2: Create Warehouse Document and Release Batch
- Create warehouse document: In warehouse shipment planning, select source documents → Create warehouse document. Quantities are immediately reserved, picking team is assigned (MOP teams only).
- Release MOP batch: In the MOP Monitor, select batch → Release MOP Batch. The system automatically executes:
- Assign MOP batch no. → all lines of the batch are displayed together in A4.1
- Assign consolidation no. → controls according to packing together rules what may be packed together
- Create picking document (type: MOP picking)
- Batch status changes to 1-Released
Hinweis
MOP batch no. vs. consolidation no.: The MOP batch no. groups all lines for A4.1. The consolidation no. controls packing — unlike series picking, items are picked order-purely into separate compartments.
Phase 3: Picking on MDE
- Open A4 Picking.
- A4.1: Batch appears as one operation (grouped by MOP batch no.).
- A4.2: Positions are displayed (cumulated only within one order).
- A4 MOP PTU LC Assignment: Assign MOP cart compartments to orders and PTUs.
- A4.3: Pick items — system validates consolidation no. when scanning into compartment.
- Batch status: 2-In Picking → 3-Picked
