INVESTIGATION REQUIREMENTS:

Investigate the discrepancy systematically before recommending any stock adjustment.

Check the following areas:

1. PHYSICAL VERIFICATION
- Recount the stock independently.
- Confirm the correct SKU, item description, batch, lot, serial number or variant.
- Confirm the unit of measure.
- Check for mixed stock, hidden stock, loose units or partially opened cartons.
- Verify that stock has not been counted twice.

2. LOCATION CHECK
- Check the assigned system location.
- Check nearby bins, racks and overflow locations.
- Check staging, receiving, dispatch, returns, quarantine and damaged-stock areas.
- Check whether stock may have been placed in the wrong location.

3. RECEIVING TRANSACTIONS
- Review recent inbound receipts.
- Compare purchase order, delivery note and goods receipt quantities.
- Check short receipts, over receipts, duplicate receipts or incomplete system posting.
- Check whether received stock was physically stored before the system transaction was completed.

4. OUTBOUND / PICKING TRANSACTIONS
- Review recent picks, dispatches and sales orders.
- Check for unconfirmed picks or shipments.
- Check incorrect picked quantities.
- Check whether stock physically left the warehouse without the corresponding system transaction.

5. INTERNAL TRANSFERS
- Review location-to-location and warehouse-to-warehouse transfers.
- Check pending, incomplete or duplicate transfers.
- Confirm both issuing and receiving locations.

6. RETURNS
- Review customer returns and supplier returns.
- Check whether returned stock was physically received but not posted.
- Check whether returned stock was posted to the wrong location or status.

7. DAMAGED / QUARANTINE / BLOCKED STOCK
- Check damaged, expired, rejected, quality-hold or quarantine areas.
- Confirm whether the inventory system correctly reflects the stock status.

8. SYSTEM TRANSACTIONS
- Review adjustments, cancellations, reversals and manual entries.
- Check transaction dates, quantities, users and reference numbers.
- Identify duplicate, missing or incorrect transactions.

9. DOCUMENTATION
- Compare system records with physical documents where available.
- Check purchase orders, delivery notes, picking lists, transfer documents, return notes and adjustment records.
- Identify documentation errors or missing approvals.

10. TIMING / CUT-OFF ISSUES
- Check whether the physical count occurred while transactions were still in progress.
- Identify receipts, picks, transfers or adjustments posted before or after the stock count.

11. ROOT CAUSE
Classify the most likely root cause, such as:
- Receiving error
- Picking error
- Transfer error
- Wrong location
- Unit-of-measure error
- Duplicate transaction
- Missing transaction
- Damage / write-off issue
- Documentation error
- Counting error
- Process-control weakness
- System / integration issue
- Unknown pending further investigation

12. CORRECTIVE ACTION
Recommend practical corrective actions to prevent recurrence.

13. STOCK ADJUSTMENT
Do not recommend a stock adjustment until reasonable investigation steps have been completed.

If an adjustment is necessary:
- Explain why.
- State the quantity to adjust.
- Identify whether it is an increase or decrease.
- State what evidence or approval should support the adjustment.
- Recommend management escalation for significant discrepancies.
