Definition
Material issue is the authorized transfer of inventory from a controlled Stores location to a department, work order, cost centre, project or point of use. Material return is the controlled movement of unused, excess or otherwise returnable material back into Stores.
Objectives
- Provide the right material in the right quantity to the authorized user.
- Prevent unauthorized withdrawal and inventory leakage.
- Maintain accurate stock balances and consumption history.
- Link material consumption to the correct department, work order, project or cost centre.
- Protect material condition and traceability.
- Recover unused or excess material where technically acceptable.
Issue Workflow
- Receive an approved material requisition or system demand.
- Verify item code, description, UOM, quantity and authorization.
- Check available and reserved stock.
- Select the correct batch, lot or serial according to issue policy.
- Pick and physically verify the material.
- Record the issue in ERP or approved transaction system.
- Obtain user acknowledgement where required.
- Update bin/location and stock balance.
- Review exceptions such as substitutions, shortages or emergency issues.
Return Workflow
- Receive return request with original issue reference.
- Verify identity and quantity.
- Inspect physical condition and usability.
- Determine whether material is reusable, requires inspection, quarantine or disposal.
- Return to the correct stock/status location.
- Record the return transaction against the original issue where practical.
- Reconcile physical and ERP balances.
Issue Categories
| Type | Typical Use | Control |
|---|---|---|
| Normal issue | Routine maintenance or production requirement | Approved requisition |
| Emergency issue | Immediate operational requirement | Emergency authorization and retrospective review |
| Project issue | Project-specific consumption | Project / WBS reference |
| Work-order issue | Maintenance activity | Work-order reference |
| Return | Unused or excess material | Condition verification |
| Replacement issue | Replacement against failed component | Failure / return traceability |
FIFO / FEFO Application
Issue sequence should follow the applicable material-rotation rule. FEFO is particularly relevant where expiry or use-by dates control usability. FIFO is commonly used where receipt age is the principal rotation factor. Critical equipment spares may require a specific issue rule based on condition, compatibility and engineering policy.
Controls
- No issue without authorized demand.
- Separate physical picking from transaction confirmation where segregation of duties is required.
- Verify high-value and critical items independently.
- Maintain serial/batch traceability where applicable.
- Investigate negative stock or repeated manual adjustments.
- Review unreturned tools, containers and temporary issues.
Common Errors
- Wrong item picked because of similar descriptions.
- Issue recorded in the wrong UOM.
- Material issued to the wrong cost centre or work order.
- Physical issue completed without ERP posting.
- Returns placed into usable stock without condition inspection.
- Old stock bypassed while newer stock is issued.
