Raw Material Issues

1. Overview & Purpose

What are Raw Material Issues?

Raw Material Issues records the physical staging and warehouse deduction of raw ingredients transferred to the factory floor. Posting an issue triggers OUTBOUND inventory stock movements and charges material costs into active Work-in-Progress (WIP).

Menu Location:Production > Material Issues

2. When to Use Raw Material Issues

Physical Ingredient Dispensing & Scale Weighing (Staging Bay)

Warehouse team dispenses and weighs 500kg of flour and 100kg of butter from raw storage racks, staging them at the mixing room loading bay.

Recommended Action:Create a Material Issue referencing the active Production Run; the system pulls standard BOM requirements and verifies physical scale weights.

Supplementary Material Requisition due to Floor Spillage

A mixing vat leaks during blending, causing loss of 15kg of liquid eggs and requiring an immediate supplementary ingredient requisition to meet nominal yield.

Recommended Action:Issue a secondary Material Issue against the same run with reason "Mixing Spillage", documenting the variance for production yield reconciliation.

Ingredient Lot Number Traceability & Quality Audit Compliance

Food safety compliance mandates recording the exact supplier lot codes of dairy and active yeast consumed in each commercial batch.

Recommended Action:Record supplier lot and batch tags on each raw material line item issued, enabling bidirectional lot tracing in the event of quality investigations.

Automated OUTBOUND Stock Deductions & WIP Value Capitalization

Ensuring digital raw inventory immediately decrements while transferring component costs into the Work-in-Progress balance sheet account.

Recommended Action:Click Submit & Post; the ERP generates OUTBOUND stock movements with PRODUCTION_ISSUE type, reducing raw storage on-hand while charging costs into WIP.

Unconsumed Raw Ingredient Floor Return to Warehouse

Excess 10kg of sugar dispensed for a run is not consumed and needs to be returned to active dry storage racking.

Recommended Action:Execute a partial Material Issue reversal or negative material voucher to return unconsumed sealed bags into raw material on-hand stock.

3. Data Dictionary & Fields

Schema structure for the production_material_issues ingredient staging table:

issueNumber	STRING(50)	Required	System-generated unique material requisition code (e.g. MI-20260522-001).
productionId	BIGINT (FK)	Required	Reference to parent production run work order.
issueDate	DATE	Required	Timestamp when raw materials were weighed and released to manufacturing floor.
status	ENUM	Required	State: DRAFT, POSTED, REVERSED, CANCELLED.
notes	TEXT	Optional	Dispensing notes, lot observations, or scale calibration tags.

5. Issuing Raw Materials

Open Material Issues Console

Navigate to Production > Material Issues from sidebar.

Select Active Production Run

Click Add Material Issue and pick target work order; BOM lines populate automatically.

Confirm Weighed Quantities

Verify physically weighed ingredient quantities against standard BOM requirements.

Submit & Post to Stock

Click Submit & Post to deduct raw stock from warehouse and transfer value to WIP.

6. Scrap & Actual Usage Variances

Review Issue Slips

Print material requisition slips for warehouse picking records.

Analyze Material Variances

Compare actual material issued vs theoretical standard BOM consumption.

7. Posting & Reversal Rules

Completed Run Inviolability

If a production run is already marked COMPLETED and finished goods have been received, material issues cannot be reversed. Reversing a material issue requires prior reversal of all associated Finished Goods Receipts.

Material Issue Reversal

If incorrect ingredients were posted, execute Reversal to return stock to warehouse.

Reversals require supervisor authorization and create audit trail movement entries.

8. Cross-Module Impact

Target Subsystem	Relational & Transactional Effect
Inventories & Stock Balances	Directly triggers OUTBOUND stock movement with PRODUCTION_ISSUE type, reducing raw material balance.
Production Work Orders (Runs)	Updates total material cost consumed by the work order for accurate COGS calculation.
General Ledger Accounting	Debits Work-in-Progress (WIP) asset and credits Raw Materials Inventory asset.

Operational Best Practices

Always mandate scale tare verification before recording weights of bulk liquid or dry ingredients.
Issue materials batch by batch rather than issuing whole-week estimates to prevent floor shrinkage.
