+# ERP Interface
+
+## Overview
+
+The ERP Interface is the integration layer between Easy WMS and the customer's ERP system (SAP, Oracle, Microsoft Dynamics, or any custom ERP). Communication is asynchronous, message-based, using a structured 3-letter code naming convention. Messages flow in both directions:
+
+- **ERP → WMS**: Master data synchronization, order creation, requests
+- **WMS → ERP**: Status notifications, order finalizations, stock events
+
+All messages have a **version** suffix when multiple variants exist (e.g., ROR01, SOR01, SOR02). The **Operation** field in each message specifies the action: `C` (Create), `U` (Update), `S` (Upsert), `D` (Delete).
+
+## Complete Message Catalog
+
+### Master Data Messages (ERP → WMS)
+
+| Code | Name | Direction | Description |
+|------|------|-----------|-------------|
+| ITM | Item | ERP → WMS | Create/update/delete items (SKU master) |
+| ITC | Item Classification | ERP → WMS | Min/max stock levels per sub-warehouse |
+| OWN | Owner | ERP → WMS | Create/update owners (3PL tenants) |
+| CAR | Carrier | ERP → WMS | Create/update carriers |
+| ACC | Account | ERP → WMS | Create/update customer accounts |
+| SUP | Supplier | ERP → WMS | Create/update suppliers |
+| KIT | Kit | ERP → WMS | Create/update kit definitions |
+| LCK | Lock Type | ERP → WMS | Lock type master data |
+
+#### ITM — Image fields
+
+The `ITM01` message can optionally convey the article's picture. Two modes:
+
+| Mode | Field | Behaviour |
+|---|---|---|
+| **Local file** | `<ItmPicture>nom-fichier.jpg</ItmPicture>` | File resolved against the folder pointed to by `UserImagesURI` in the WMS `appsettings.json`. Typical value : `C:/MLX/Data/Pictures/`. |
+| **URL** | `<ItmPictureUrl>https://…/photo.jpg</ItmPictureUrl>` | Fetched by the WMS when the client uses the display; `ItmPicture` takes precedence if both are present. |
+
+> Requires read access on the `UserImagesURI` share from the WMS service account. The image is not uploaded via the ITM file — only the filename / URL is stamped on the item record.
+
+---
+
+### Inbound / Receipt Messages
+
+#### ROR — Receipt Order (ERP → WMS)
+
+The primary message for creating inbound orders.

+
+**Triggered by:** `INO.CST` transaction
+

+
+**Versions:**
+- `ROF01`: Standard finalization
+- `ROF02`: Extended with detailed line-level quantities — **the version generated when closing an inbound order sourced from a `Transfer` shipping order** (two-warehouse flow). For standard supplier receipts, ROF01 is emitted.
+
+**Key fields:**
+| Field | Description |

+
+**Notes:**
+- Sent only when a receipt with actual received stock is closed
+- Sent for blind receipts (no associated receipt order)
+- Includes detailed line-level stock received data
+
+**Key fields:**
+| Field | Description |
+|-------|-------------|
+| Site | Warehouse code |
+| ReceiptCode | Receipt code |
+| Status | Closed |
+| RecDatContainers | Number of containers received |

+| Lines[].LneStockQty | Stock quantity |
+| Lines[].LneStockWeight | Weight |
+| Lines[].LneStockRecDate | Receipt timestamp |
+
+**Triggered by:** `REC.CLS` transaction
+
+---
+
+#### ASO — Advanced Shipping Notice OK (WMS → ERP)
+
+Confirms that a pre-notified container has been successfully received.
+
+**Triggered by:** `CON.ASN.001` transaction (ASN container received) or `CON.PIE` (container entered via PIE)

+| ReceiptOrderCode | Associated receipt order |
+| ReceiptCode | Receipt document |
+| ReceivedDate | Reception timestamp |
+
+> **DirectTransfer trigger** — when the expedition of a `<DirectTransfer>` shipping order is closed at the origin warehouse, EasyWMS automatically generates an `ASO01` message targeting the destination warehouse, creating the incoming ASN container(s). The ASO carries the container and its stock but **no reference to the originating `SorCode` / DirectTransfer header**. See [concepts/order-outbound.md](order-outbound.md#asn--directtransfer-flow).
+
+---
+
+#### ASK — Advanced Shipping Notice KO (WMS → ERP)
+
+Notifies ERP that a pre-notified container has been rejected or deleted.
+
+**Key fields:**
+| Field | Description |
+|-------|-------------|
+| Site | Warehouse code |
+| ContainerCode | Rejected container |
+| ReceiptOrderCode | Receipt order (optional) |
+| CancelDate | Rejection timestamp |
+
+**Triggered by:** `CON.CNL.ASN` transaction
+
+> **DirectTransfer trigger** — deleting an ASN container of a DirectTransfer flow from SmartUI (`Entrepôt → Conteneurs ASN → Supprimer`) generates an `ASK01` to the ERP. As with the ASO, the message contains no reference to the upstream shipping order.
+
+---
+
+#### SRO — Stock Replenish OK (WMS → ERP)
+
+Confirms that pre-notified loose stock has been used for automatic warehouse replenishment.
+
+**Triggered by:** `STK.REP.001` transaction
+
+---
+
+#### SRK — Stock Replenish KO (WMS → ERP)
+
+Notifies that pre-notified loose stock has been canceled (not used for replenishment).
+
+**Triggered by:** `STK.REP.CNL` transaction
+
+---

+| Lines[].LneQtyReserve | Stock reserve quantity |
+| Lines[].ShipExpiredStock | Ship only expired stock |
+| SOR02: PrpContTypeRequired | Required client container type |
+| SOR02: VASCode | VAS template |
+
+**`SorType = DirectTransfer`** — inter-warehouse transfer; closing the expedition at origin emits an automatic `ASO01` on destination, pre-creating the ASN container (see [ASO](#aso--advanced-shipping-notice-ok-wms--erp) and [concepts/order-outbound.md](order-outbound.md#asn--directtransfer-flow)).
+
+**`SorType = Transfer`** — inter-warehouse transfer variant where destination generates **a full inbound order** on expedition close (as opposed to DirectTransfer which only pre-notifies via ASN). The destination ROR carries the source SOR reference ; on close, destination emits a `ROF02` carrying the line-level quantities, which the origin warehouse uses to reconcile. See [concepts/order-outbound.md](order-outbound.md#transfer-two-warehouse-flow).
+
+---
+
+#### SOC — Shipping Order Status Change (WMS → ERP)
+
+Notifies ERP of shipping order status transitions.

+| Status | Closed / Canceled |
+| ClosingNumber | Closing sequence number |
+| Lines[].LneNumber | Line number |
+| Lines[].LneQtyShipped | Shipped quantity |
+| Lines[].LneQtyUoMCode | Unit of measure |
+
+**Triggered by:** `OUT.CLS` / `OUT.CNL` transactions
+
+---
+
+#### DlvShareDeliveries — Merge outbound orders (ERP → WMS)
+
+XML message used by the **Multi-Carrier / Deliveries module** to request that two or more outbound orders be prepared together (merged). A merged group shares client containers, carrier call, and closure.
+
+**Eligibility** — all orders in the request must match on:
+
+- Same account
+- Same site (warehouse)
+- Same route or delivery address
+- Same carrier
+
+When `ALLOW_MERGE_DIFFERENT_ACCOUNT = true` is set, the "same account" rule is relaxed (cross-account merges become possible).
+
+**Effect on orders:**
+
+- Stock assignment is executed across the merged scope (not per-order)
+- Client containers can carry lines from any order in the group
+- Order closure is triggered when the last line of the last order in the group is picked / when the carrier call returns
+- SOF is still emitted per source SOR — only preparation is shared

+## Integration Architecture
+
+### Message Flow
+
+```
+ERP ──[async message]──→ WMS Integration Queue
+WMS Integration Queue ──→ WMS Core (processes message)
+WMS Core ──[transaction]──→ Post-processor
+Post-processor ──[async message]──→ ERP Response Queue
+ERP Response Queue ──→ ERP
+```
+
+### Transaction Post-processing
+
+Many WMS transactions are marked **"Post-processed: yes"** — meaning after the internal transaction is written, a background post-processor generates the corresponding ERP message:

+### Module-Specific ERP Messages
+
+Beyond the core catalog, optional modules add their own ERP messages:
+
+| Module | Message | Direction | Description |
+|--------|---------|-----------|-------------|
+| Manufacturing | RCP01/RCP02 | ERP → WMS | Recipe (BOM) create/update/delete |
+| Manufacturing | MOR01 | ERP → WMS | Manufacturing production order create/update/delete |
+| Manufacturing | MOF | WMS → ERP | Manufacturing order finalization (closed or cancelled) |
+| Manufacturing | FGP | WMS → MES | Finished goods produced notification (MES integration) |
+| Kits | WOR | ERP → WMS | Work order for kit assembly or disassembly |
+| Kits | WOF | WMS → ERP | Work order finalized (ERP-originated orders only) |
+| Kits | KST | WMS → ERP | Kit manually assembled (manual work orders) |
+| Kits | UNK | WMS → ERP | Kit manually disassembled (manual work orders) |
+| Store Fulfillment | TOR01 | ERP → WMS | Transfer order between stores/sub-warehouses |
+| Store Fulfillment | TOF01 | WMS → ERP | Transfer order finalized |
+| Store Fulfillment | TPV01 | ERP → WMS | POS sale notification — decrements store stock |
+| VAS | VAS01 | ERP → WMS | Create/update VAS templates, activities, and instructions |
+| VAS | SOR02 VASCode | ERP → WMS | VAS template reference per line in shipping order |
+| VAS | SOF (VAS field) | WMS → ERP | VAS model used + quantity returned per shipped line |
+| Slotting | SAC01 | WMS → ERP | ABC rotation classification suggestion (sent after manual recalculation) |
+| DOM | POR/ROC/SOR/SOC/SOF/DOF/ACK/NCR | Both | Multi-node orchestration |
+| Yard Management | Appointment sync | Both | ERP/TMS appointment exchange |
+| Counting | SCR/WSC | Both | Stock contrast |
+
+**SAC01 detail**: sent manually from SmartUI after running the ABC rotation analysis in the WMS. Contains item code + suggested ABC class. The ERP uses this to update item classification. Only sent when the WMS operator explicitly triggers it (not automatic).
+
+**TPV01 detail**: sent by POS (point of sale) system when a store sale occurs. EasyWMS decrements the corresponding store sub-warehouse stock in real time, providing a live stock view per store. Requires Store Fulfillment module.
+
+**TOR01/TOF01**: used by the Store Fulfillment module to manage inter-store replenishment. TOR01 creates the transfer order from ERP; TOF01 is returned when the transfer is complete.
+
+## Common Errors
+
+| Symptom | Cause | Solution |
+|---------|-------|---------|
+| ROR creates order but lines fail | `transactional` group not set, line validation error | Check item/UoM existence; review partial creation log |
+| ASN container arrives but no ASO sent | Post-processor not running | Check integration pool and post-processor service |
+| SOR rejected: item not found | Item not yet synced via ITM | Send ITM first, then SOR |
+| STR applies lock but no STC received | Stock matching filters returned zero results | Verify item/owner/lot combination exists |
+| SOF never received | Shipping order not yet closed in WMS | Check order status; may be in Prepared status awaiting manual close |
+| COR count created but COF never sent | Count was created from UI (not ERP-initiated) | COF only sent for ERP-initiated counts |
