Optimizing Goods Receipt: WMS and WCS Collaboration Guide

WMS – WCS Workshop: Inbound Goods Receipt

Aligning Process Flows, System Boundaries, and Interfacing for Automation

Scope: Supplier Reception (Pallet AS/RS) | Objective: Alignment & Ownership

Workshop Agenda

1. Context & Assumptions (Scope, Automation triggers) <br> 2. Physical Inbound Flow (From Truck to AS/RS) <br> 3. System Roles (WMS vs WCS splitting) <br> 4. Message Exchange (Sequence & Data) <br> 5. Exception Handling (Blind receipts, Rejections) <br> 6. Summary & Next Steps

Scope & Assumptions: Pallet Inbound

<h3>IN SCOPE</h3><ul><li>Third-party supplier receipt of homogeneous pallets.</li><li>Cross-dock / Flow-through operations.</li><li>Handling of "Blind Receipts" (Missing ASN).</li><li>Pallet AS/RS induction via Conveyors & Scanning.</li></ul>

<h3>OUT OF SCOPE</h3><ul><li>Loose carton receiving / Mixed SKU pallets.</li><li>Detailed serial number tracking (at this stage).</li><li>Transport Management System (TMS) integration.</li><li>Non-automated storage areas.</li></ul>

Physical Inbound Flow (No Systems)

Key Alignment: The physical movement drives the logical events.

1. Arrival & Docking &nbsp; ➔ &nbsp; 2. Unload & ID &nbsp; ➔ &nbsp; 3. AMR/Staging &nbsp; ➔ &nbsp; 4. Conveyor Induction &nbsp; ➔ &nbsp; 5. AS/RS Storage

System Responsibilities: WMS vs WCS

<strong>WMS (The Brain)</strong><br><br>• Owns Inventory & Receipts<br>• Validates Expected SKUs (ASN)<br>• Decides Quality Status (Q hold)<br>• Handles Business Exceptions<br>• Triggers 'Store' Command

<strong>WCS (The Muscle)</strong><br><br>• Controls Equipment (Conveyors, Cranes)<br>• Manages Routing Logic & traffic<br>• Reads Barcodes/RFID physically<br>• Reports Execution Feedback (Done/Fail)<br>• Handles Technical Faults

Message Exchange Sequence

<ol><li><strong>ASN / Pre-Advice</strong> (WMS has data)</li><li><strong>Scan / Arrival</strong> (WCS queries WMS)</li><li><strong>Validation</strong> (WMS confirms SKU/Qty)</li><li><strong>Induct</strong> (WCS tracks movement)</li><li><strong>Putaway Confirmed</strong> (WCS -> WMS)</li></ol>

Note: WCS does not store inventory levels, only current location of a pallet ID.

Exception Scenarios: Inbound

Blind Receipt (Missing ASN)

Physical Profile Rejection

Pallet arrives, ID scan yields no result in WMS.<br><strong>Decision:</strong> Quarantine lane or Manual Entry Station?<br><strong>Action:</strong> Operator manual intervention required.

WCS detects pallet overhang or weight issue.<br><strong>Decision:</strong> Reject loop to rework station.<br><strong>Action:</strong> WCS updates WMS with 'Profile Error' status.

Workshop Discussion & Decisions

<strong>DECISIONS NEEDED:</strong><br><br>1. Process for Blind Receipts agreed?<br>2. Rejection Loop ownership validated?<br>3. Scan point location fixed?
