# Container (LPN)

## Overview

A **LPN** (License Plate Number) is the fundamental unit of physical storage in EasyWMS - a box, pallet, or any other container that holds stock. Every unit of stock in the warehouse lives inside a LPN; the LPN is what moves, what gets located, locked, picked, and shipped. In identification contexts, the LPN is always labeled (Code 128 or GS1-128) and its code uniquely identifies it system-wide.

The LPN is the bridge between the physical world (a pallet on a rack) and the logical world (stock records, tasks, orders). EasyWMS tracks every LPN's location, weight, status, contents, and relationships (stacked, matched, client-linked) in real time. All WMS movements - reception, putaway, picking, replenishment, shipping - are expressed as operations on LPNs.

The term "container" in EasyWMS source documentation is synonymous with LPN. The entity name in the Application Dictionary is **Container**; the UI and documentation use both terms interchangeably.

---

## Main Attributes

| Property | Description |
|---|---|
| **Code** | Unique identifier. Usually an **SSCC** (18 numeric digits per GS1 standard). Characters `&`, `<`, `>`, `` ` `` are not allowed. Validated against GS1 format if `LPN_CHECK_CODE_GS1LABEL` is active. Can be checked for uniqueness vs. station codes, locations, and item aliases via `CONTAINER_CHECK_CODE_REPEATED_FOR_LABELS`. |
| **Type** | Physical LPN type (e.g. EuroPallet, American pallet, box). Defines dimensional and weight constraints. Configured in EasyS. |
| **Location** | Current warehouse location where the LPN is stored. |
| **Height** | Measured in mm. Set by: PLC/SCA gauge at PIE station, user input during reception, ASN pre-notification, or manual screen edit. Includes the max height of any LPN stacked on top. |
| **Occupation percentage** | % of LPN capacity used by its stock. Not calculated automatically by EasyWMS - editable from the LPN view or set by the user. |
| **Is client LPN** | Boolean. `true` if the LPN's stock is assigned to a shipping order (outbound). Drives picking, shipping, and consolidation logic. |
| **Division type** | Internal partition configuration (see [Division Types](#division-types)). Only supported in automatic warehouses. LPNs with divisions only accept entry and picking tasks - shipping tasks are invalid. Content must be fully picked out before division LPN is used for shipping. |
| **Status** | Current lifecycle state (see [Lifecycle & Statuses](#lifecycle--statuses)). |

### Weight Properties

EasyWMS maintains five weight values per LPN. Only **Calculated weight** is applied to capacity restrictions (location max weight, equipment max weight).

| Weight Property | Description |
|---|---|
| **Theoretical weight** | Computed: sum of stock line theoretical weights + LPN type empty weight. |
| **Real weight** | Theoretical weight of this LPN + sum of theoretical weights of all stacked LPNs on top. |
| **Scale weight** | Reported by WMS after LPN passes a scale (SCA), or entered manually by a user. |
| **Theoretical scale weight** | Scale weight corrected each time stock quantity changes (recalculated from stock theoretical weight). |
| **Calculated weight** | `max(Real weight, Theoretical scale weight)`. This is the value used for all weight-based restrictions. |

> 📖 For variable-weight items, PIE passage behaviour, and the complete formula walk-through see [Weights](weights.md). Note: the internal "Real weight" field in the Container entity is `max(Calculated, Theoretical Scale)` whereas the definition above (used for stacking capacity checks) aggregates stacked containers. Both are documented side-by-side in [Weights](weights.md).

## Types

### LPN Types

LPN types define the physical characteristics of an empty LPN. Configured in the **EasyS** tool, not in the WMS UI.

| Attribute | Unit | Description |
|---|---|---|
| Length | mm | Bottom length of the LPN |
| Width | mm | Width of the empty LPN |
| Height (empty) | mm | Height when the LPN is out of stock |
| Maximum height | mm | Max height the LPN can reach when loaded with stock |
| Weight (empty) | kg | Weight of the empty LPN |
| Maximum weight | kg | Max safe weight when loaded |
| Collapse | mm | Max width deviation due to load collapse. Effective width = Width + 2 × Collapse. |

The collapse parameter matters for automatic warehouse location sizing - the system checks effective width when searching for a putaway location.

**UI path:** EasyS tool (not EasyWMS web UI).

### Division Types

Storage LPNs can have **internal partitions** (divisions). Used to optimize space and organize stock by item within a single physical LPN. Only supported in **automatic warehouses**.

| Attribute | Description |
|---|---|
| Name | Unique identifier for the division type |
| Description | Free text |
| Columns | Number of column partitions |
| Rows | Number of row partitions |
| Section | Section assignment within the division |

Rules:
- LPNs with divisions only allow entry and picking tasks. Shipping tasks are not valid.
- Contents must be picked out before the LPN can be considered empty.
- Division type can only be modified or removed from an **empty** LPN.

**UI path (web):** `Masters > Division LPN types`

### Client vs. Non-Client LPN

A critical distinction throughout EasyWMS:
- **Non-client LPN**: Holds stock available for general warehouse use (putaway, replenishment, picking source).
- **Client LPN**: Stock has been assigned to a shipping order. The LPN is "committed" to a specific outbound flow. Stacking/matching rules differ between client and non-client LPNs.

---

## Lifecycle & Statuses

LPN status tracks the full journey from pre-notification through shipment:

```
[ERP pre-notifies ASN]
        ↓
  PENDING RECEIPT   ← LPN in virtual ASN location, not yet physically received
        ↓
   [Reception process]
        ↓
    AVAILABLE        ← LPN in warehouse, free to use for any process
        ↓
   [Picking/consolidation starts]
        ↓
  IN PREPARATION     ← LPN being received, client LPN being prepared, or in consolidation
        ↓
   [Picking complete]
        ↓
    PREPARED         ← Client LPN picked but not yet ready for loading
        ↓
   [Moved to shipping stage]
        ↓
 READY FOR SHIPPING  ← Client LPN in shipping stage awaiting truck load
        ↓
   [Truck loading]
        ↓
     LOADED          ← Included in a load but not yet departed
        ↓
   [Truck departs]
        ↓
    SHIPPED          ← LPN has left the warehouse
```

**Note**: The "In preparation" status also covers LPNs currently on equipment during any movement task.

---

## Stacking and Matching

EasyWMS supports two forms of LPN grouping to reduce storage and transport costs:

| Relationship | Axis | Description |
|---|---|---|
| **Stacking** | Vertical | LPNs stacked on top of each other. A hierarchy is established: base LPN → stacked LPN(s). |
| **Matching** | Horizontal | LPNs aligned side by side. Uses a **slave/dummy LPN** as the logical container. |

### Stacking Rules

- LPNs must all be client type OR all non-client type.
- If client LPNs, they must all be for the same shipping order or for different orders on the same route stop.
- If a shipping order specifies a required LPN type, only client LPNs of that type can be stacked.
- Stacking relationships between LPN types must be configured in **EasyS** (how many LPNs of type X can stack on type Y).
- Supported location types for stack/match: Shelves (conventional/rack), Buffer, Stage, Dock, Lost & Found.

### End Location for Stacking

| LPN type | Location type | Behavior |
|---|---|---|
| Client LPN | Floor (buffer/stage/dock) | End location not requested; stays at base LPN location |
| Non-client LPN | Floor (buffer/stage/dock) | Controlled by `ASK_FINAL_STACK_LOCATION` parameter |
| Any | Shelves / virtual | Operator must always specify end location |

### Matching (Slave LPN)

Slave/dummy LPN configuration at equipment level:
- **With slave**: always uses a slave LPN
- **No slave**: never uses a slave LPN
- **Ask slave** (default): asks the operator each time

### Unstacking

- Cannot unstack base LPN from locations with FIFO configuration or rack type (when different LPN types are above).
- `UNSTACK_ON_STAGE` parameter: if `true`, forces unstacking to happen at a stage (both unstacked and remaining set land at the stage).
- **Undo all**: breaks all stacking/matching relationships in a set at once; all LPNs are placed loose in a buffer location.

---

## Lock Types

Locks restrict what operations can be performed on a LPN. Multiple locks can be applied simultaneously unless a lock is marked **Exclusive** (in which case it cannot coexist with other locks).

### Lock Properties

| Property | Description |
|---|---|
| Description | Text describing the physical reason (e.g., "broken wood", "stock misplaced") |
| Exclusive | If enabled, no other lock type can be active at the same time |
| Allow picking | If active, picking is allowed |
| Allow shipping | If active, shipping is allowed |
| Allow putaway | If active, putaway is allowed |
| Allow counting | If active, counting is allowed |
| Allow moving | If active, physical movement is allowed |
| Allow replenishment | If active, replenishment is allowed |
| Allow reserving | If active, stock reservation is allowed |
| Allow internal consumption | If active, LPN can be consumed in manufacturing |

### Cascade Effects When Locking

When a lock is applied that restricts a specific operation, EasyWMS automatically cascades the impact to in-progress tasks:

**Lock does not allow replenishment:**
- All replenishment source assignments for this LPN's stock are canceled.
- Picking tasks that used this stock as their assigned source are decremented (if they had other stock) or canceled (if this was the only stock).
- Released lines are re-released for new assignment.

**Lock does not allow picking:**
- All replenishment source assignments are canceled (stock unavailable for picking).
- Picking tasks using this LPN's stock are decremented or canceled.
- Affected lines are re-released.

**Lock does not allow moving:**
- If LPN is in a dynamic or pushback location, locks automatically propagate to LPNs behind it.
- Auto-unassignment of affected client LPNs.
- Affected tasks canceled; lines re-released.

**UI path (web):** `Masters > Lock types` → View "LPN lock types"

---

## Reception of Containers

### ASN Pre-notified Containers

LPNs pre-notified by the ERP via ASN message arrive in **Pending receipt** status and appear in the virtual **ASN location**. They are listed in the "ASN LPN" view until physically received.

**UI path (web):** `Warehouse > ASN LPN`
**UI path (RFT):** `Receipts > Notices`

### Supplier Multi-reference Container Receipt

Non-pre-notified stock arriving from a supplier in containers with multiple items. Two modes:

| Mode | Description |
|---|---|
| **Receipt and putaway** | Stock received on equipment; location search runs immediately for putaway. |
| **Receipt on stage** | Stock registered in a stage; putaway done later by another operator or batch. |

A third variant: **exclusive reserve** - stock can be reserved for a specific shipping order at receipt time (configured via ROR message from ERP, see [erp-interface.md](../concepts/erp-interface.md)). The `CONFIRM_EXCLUSIVE_RESERVE_ASSIGNMENT` parameter controls whether the user must manually select the shipping order when multiple compatible orders exist.

**ERP message sent at end of receipt:** `REF`
**Transactions:** `CON.RECEP` (per container), `STK.RECEP` (per stock line)
**UI path (RFT):** `Receipts > Supplier > Loose stock/multi-reference`

### Blind Container Receipt

Unplanned, non-pre-notified stock with no entry order. A receipt is auto-created at the start and closed at end. The receipt cannot be manually created or edited in the WMS UI.

**ERP message sent:** `REF`
**Transactions:** `CON.RECEP` (per container), `STK.RECEP` (per stock line)
**UI path (RFT):** `Receipts > Blind > Loose stock/multi-reference`

### Partitioned Container Receipt

Both supplier and blind modes support receiving containers with internal partitions. Destination must always be an **automatic warehouse** - containers must be transported to a PIE or picking station after reception.

## Operations

Available actions on LPNs (full list from web UI):

| Operation | Description | Equipment |
|---|---|---|
| LPN register | Register a LPN found at a location not known to the system. Specify code, location, type, height, weight, divisions. Some locations require position (rack) or depth (dynamic/compact/APS). | PC |
| Stock register in LPN | Add stock to a newly registered or unknown LPN. Requires item, owner, quantity, UoM. Treated as stock adjustment (reason required). | PC |
| Delete LPN | Remove LPN. If not empty, deletes all stock (stock adjustment, reason required). ASN LPN can only be deleted if not linked to a receipt order. | PC |
| Lock / Unlock | Apply or remove a lock type. Requires lock type selection; end date and comment optional. | PC |
| LPN type modification | Change the LPN type. Only for **empty** LPNs. | PC |
| Division type modification | Change division type. Only for **empty** LPNs. | PC |
| Delete division | Remove division from LPN. Only for **empty** LPNs. | PC |
| Location change | Change LPN's recorded location. Does NOT create a movement task - only updates the data record. Treated as [manual movement](../concepts/manual-movements.md). In open APS FIFO channels, only accessible locations shown. | PC / RFT |
| Send to Lost & Found | Send LPN to virtual L&F location when physical location unknown. In APS FIFO, only accessible or last LPN in channel. Stacked LPN: entire partial block (selected LPN + children) goes to L&F. | PC |
| Relocation (automatic warehouses) | Change physical location via system-directed move: Automatic (putaway strategies), To an aisle (putaway strategies in selected aisle), To a location (no strategies, physical compatibility only), To a level (putaway strategies in selected level). | PC |
| Mark as full / not full | Flag LPN as full so replenishment at PK conveyor skips it. Manual additions still possible. | PC |
| Mark division as full / not full | Same as above for a specific division within a LPN. | PC |
| Shipping order unassignment | Unlink LPN from its shipping order. Works for mapped, prepared, or loaded LPN. No movement task created - operator is responsible for physical move. | PC |
| Extraction request to PK conveyor | Request extraction from a station to a Picking conveyor for an action outside the system. | PC |
| Request empty LPN to PK | Request empty LPN(s) of specific type/divisions to be sent to a Picking conveyor. | PC |
| Extraction request to PS conveyor | Request extraction to an Outbound conveyor (PS). | PC |
| Request empty LPN to PS | Extract empty LPN to Outbound conveyor (often to fill outside PK, e.g., for reception). | PC |
| Set depth coordinate | APS3D only - manually set depth coordinate for a LPN in an APS location. Superadmin only. | PC |
| Manual compacting | APS/APSFIFO: compact LPN when free positions exist in front. | PC |
| Exchange LPN | APS3D only - swap a LPN in channel for one outside; must be same type. Superadmin only. | PC |
| Consulting equipment LPNs (My LPNs) | View all LPNs on own equipment: code, type, status, stock lines (item, qty, UoM, logistic attributes). Can unload or reject LPNs from this view. | RFT |
| Putaway search location trace | Report of last location search for this LPN. Shows strategies applied, excluded aisles, routes with issues, reserve percentages, stock line details. Superadmin sees full technical trace. | PC |
| Stack / Match LPNs | Group LPNs vertically (stack) or horizontally (match). | RFT |
| Unstack / Unmatch LPNs | Dissolve a stacking or matching relationship. | RFT |
| Label printing | Print/reprint LPN label (Code 128 or GS1-128). | PC / RFT + Labeller |
| Pre-printed label generation | Print blank LPN code labels for use in reception/creation processes. Follows UCC config and LPN sequence. | PC / RFT + Labeller |
| Client LPN label printing | Print client label for prepared client LPNs. Shows: LPN code, account, shipping order, current date. | PC / RFT + Labeller |
| Delivery note printing | Print packing slip for prepared or shipped client LPN. Shows: LPN code, shipping order, recipient name/address, carrier, stock detail (item, qty, UoM, weight, logistic attributes). | PC / RFT + Printer |
| View rejects | Consult reject reasons for LPNs at a station. | RFT |

## Labeling & Identification

EasyWMS interprets the following **GS1 Application Identifiers (AI)** on existing LPN labels:

| AI | Meaning |
|---|---|
| (00) | SSCC - Serial Shipping Container Code |
| (01) | GTIN grouping code / DUN14 |
| (02) | EAN |
| (10) | Lot number |
| (11) | Manufacturing date |
| (15) | Preferred consumption date |
| (17) | Expiry date |
| (21) | Serial number |
| (37) | Quantity |

**AI 02 special behavior:** When receiving items with an item-to-container-type conversion (complete quantity rule) labeled with GS1-128, using AI 02 forces the user to manually enter the received quantity rather than auto-completing the container.

### Changing the SSCC prefix

The SSCC prefix used for containers generated by the WMS (picking, and reception if the toolkit is enabled) is set **in EasyS**, not in SmartUI. Typically required when a customer mandates GS1-compliant codes.

Procedure:
1. In EasyS, **double-click** the warehouse name
2. Fill in the desired **prefix**
3. **Save**

Existing LPN codes are not rewritten - only containers generated after the change use the new prefix.

---

## Parameters

## Common Errors

**LPN not found at expected location:**
- Symptom: Physical LPN present but system shows different location.
- Cause: Manual move not recorded, or system error during task.
- Solution: Use "Location change" (PC) to correct the record. Treat as manual movement (no task required). If location unknown, send to Lost & Found.

**Cannot unstack base LPN:**
- Symptom: Unstack operation rejected.
- Cause: Location has FIFO configuration, or different LPN types are stacked above the base.
- Solution: Move the set to a stage first (enable `UNSTACK_ON_STAGE`), or use "Undo all" to break the entire hierarchy at once.

**Lock prevents task execution:**
- Symptom: Task canceled unexpectedly after LPN lock applied.
- Cause: Lock type disallows picking, replenishment, or moving. Cascade effect automatically cancels in-flight tasks.
- Solution: Check lock type configuration. Unlock the LPN if the reason is resolved, or process via alternative stock.

**Cannot modify LPN type or division:**
- Symptom: Type/division change rejected.
- Cause: LPN is not empty - contains stock.
- Solution: Move or pick out all stock first, then change the type.

**Putaway location not found for stacked LPN:**
- Symptom: Location search returns no result for stacked set.
- Cause: Effective width (width + 2 × collapse) exceeds available location dimensions, or no valid strategy applies to the stack configuration.
- Solution: Check the "Putaway search location trace" report for the LPN (requires PC). Review excluded aisles and strategy details.

**ASN LPN cannot be deleted:**
- Symptom: Delete operation rejected for an ASN LPN.
- Cause: The ASN LPN is linked to a receipt order (ROR).
- Solution: Cancel or disassociate the receipt order first, or use the rejection flow (`CON.CNL.ASN` → `ASK` message to ERP).
