WMS Enabled Discrete Manufacturing – WIP Issue & WIP Return

Business Requirements Context: Business manufactures components and assemblies that require controlled issuance of raw materials to Discrete Jobs on the shop floor. They want to ensure:

- Barcode driven material picking
- Accuracy in inventory consumption
- Real time visibility of WIP transactions
- Minimized paper usage
- Traceability using LPNs (License Plate Numbers)
- Warehouse efficiency through RF devices

Oracle WMS integrated with WIP (Work in Process) supports all of these.

Manufacturing Scenario Overview

Example Product: Breaker Assembly (Discrete Job: JOB-HB-100245)

Required Components:

Component UOM Qty Required

Copper Busbar EA         2

Magnetic Coil         EA         1

Bolts (Pack of 10)         PK         1

Subinventory         Locator Controlled LPN Controlled

RM-COPPER Yes Yes

RM-COIL                 Yes No

RM-FASTENERS Yes Yes

How Oracle WMS Supports Discrete Job Transactions

1. Discrete Job Creation (WIP Module)

Planner creates a Discrete Job:

Job Number:         JOB-HB-100245

Assembly Quantity: 10 units

Status:         Released

Routing/Operations:       Assigned for assembly work center

Once released, the job is visible to Oracle WMS mobile pages for material picking.

2. WMS-Driven WIP Component Picking (WIP Issue)

Warehouse Workflow: The warehouse operator uses an RF device (Mobile Supply Chain Application - MSCA).

Step-by-Step:

Step 1: Mobile Task Generation

System creates tasks for required components

Tasks appear in WMS as WIP Component Pick Tasks

Assigned to warehouse personnel

Step 2: Operator Picks Components

Operator logs into WMS handheld and selects: Tasks → WIP → Component Pick

They scan: Subinventory > Locator > LPN (if applicable) > Component > Lot/Serial (if applicable)

System validates:

On-hand availability

Correct component for the job

Exact required quantity

No need to access WIP module directly, WMS handles it.

Step 3: WIP Issue Transaction

Upon confirming pick:

WMS performs a WIP Issue in the background

Inventory is relieved from warehouse subinventory

Components are moved to WIP supply subinventory logically

Transaction visible in:

WIP Material Transactions

Material Transaction Summary

Discrete Job Material Tab

Result: Materials are issued to the shop floor controlled, accurately, and in real time through WMS.

3. WIP Return (Returning Excess/Unused Material)

If Business returns unused materials:

Operator selects: WIP → Component Return

Steps:

Scan Job

Scan component

Enter return quantity

Scan destination subinventory/locator/LPN

Confirm

System performs a WIP Return transaction:

Material moves back into warehouse inventory

WIP material requirement updates automatically

Real-time visibility restored

4. Additional WMS Benefits for Business

• LPN based Picking : Entire pick can be performed by scanning one LPN containing multiple parts.
• Lot/Serial Control: Mandatory for electrical components; WMS ensures correct traceability.
• Task Management: Supervisors can: Allocate tasks | Reassign | Monitor task completion in real time
• Automated Material Staging : Components can be staged at operation level WIP supply locators using WMS.
• Exception Handling: Operators can record exceptions: Short pick | Substitution | Damaged items |Partial issue
