Receiving DiscrepancyInvestigation.

Act as a warehouse receiving and inventory-control specialist. Help me plan an evidence-based investigation; do not pretend to have inspected goods or checked records.

TASK:
Compare the expected delivery, physical receipt and system posting. Identify what needs verification before receipt correction, stock release or escalation.

RECEIPT CONTEXT:
[Purchase order, transfer, return or other receipt; warehouse and receiving location. Use anonymized references.]

EXPECTED DELIVERY:
[SKU, quantity due on THIS delivery, UOM, confirmed pack conversion, PO/ASN/delivery-note quantities. Distinguish total order quantity from scheduled or remaining delivery quantity.]

PHYSICAL COUNT:
[Count by SKU, location and condition; count time; counted/recounted by role; batch, expiry or serial details where relevant. State whether damaged or held units are included in the total.]

SYSTEM RECEIPT:
[Quantity, UOM, location, status and posting time; unposted, partial, completed, reversed or unknown. Include earlier partial receipts where relevant.]

DISCREPANCY:
[Shortage, overage, wrong SKU, damage, UOM, batch/expiry, serial, label or system posting issue.]

EVIDENCE:
[Count sheets, documents, labels, photos, seal records, scan logs or transaction history. Describe what is available and what remains unverified.]

ACTIONS ALREADY TAKEN:
[Recount, segregation, hold, put-away, receipt posting or escalation.]

APPLICABLE CONTROLS:
[Provided acceptance rules, tolerances, approval roles, quality requirements and claim deadlines. Write unknown where not supplied.]

COST AND IMPACT, IF KNOWN:
[Unit cost and currency, affected orders or production. Do not supply confidential data unnecessarily.]

INVESTIGATION RULES:
- Separate supplied facts, calculations, hypotheses and checks still needed.
- Use the same SKU, UOM, delivery scope and cut-off time for each comparison. Ask for missing conversions; never invent pack sizes.
- A PO states an order quantity, not proof of what was loaded or delivered. A matching seal alone does not establish the loaded quantity or responsibility.
- Missing, damaged, held and available quantities are different. Do not double-count damaged units as both missing and physically received.
- Do not assume a root cause, invent evidence, simulate completed checks or assign blame.
- No AI output authorizes receipt posting, adjustment, release, rejection, return or a claim. Identify the decision and the role that must confirm it under supplied procedures.

1. RECONCILE THE QUANTITIES
Show a table for each affected SKU with expected delivery, physical total, damaged/held subset and system receipt. Mark unknown values explicitly.
Calculate signed delivery variance = physical total minus expected delivery.
A negative value is a shortage; a positive value is an overage.
Calculate system-versus-physical difference only when both quantities cover the same receipt and status scope. An unposted receipt is a pending transaction, not automatically an inventory shortage.
Show working and units. Calculate value only with a provided cost in the same UOM and a stated currency. Separate missing-stock value from damaged-stock value; neither establishes a recoverable claim.

2. PRIORITIZE VERIFICATION
Start with an independent recount and confirmation of SKU, UOM, pack size and delivery scope. Check staging, adjacent locations, mixed pallets, loose units and earlier partial receipts.
Compare PO, ASN, delivery note, packing list and physical labels; do not assume any document proves the physical count.
Review system receipt identifiers, quantities, UOM, timestamps, locations, reversals and duplicate or pending postings.
For each check, state the question, evidence required, proposed role and what the result would change. Mark roles as proposed if responsibility was not provided.

3. CHECK THE RELEVANT EXCEPTIONS
Use only applicable branches; do not fill every branch with generic findings.
- Shortage/overage: examine loading and unloading counts, partial deliveries, mixed deliveries and counting errors.
- Wrong SKU/UOM/label: compare actual product identifiers, supplier codes, barcode mappings and verified conversion factors.
- Damage: record affected quantity and condition, preserve packaging/photos and review handling evidence. Do not infer when damage occurred from appearance alone.
- Batch/expiry/serial: compare documents, labels, physical identifiers and system records; apply only supplied acceptance rules.
- Seal/transport: compare seal and vehicle records and available handover evidence without assuming liability.

4. ASSESS EVIDENCE AND CAUSES
List each plausible explanation with supporting evidence, contradictory or missing evidence and the next check.
Keep the cause unresolved where evidence is insufficient. Use 5 Whys only when each link has support; label unanswered questions rather than inventing a chain.
Distinguish the quantity discrepancy from any demonstrated process failure.

5. PLAN CONTAINMENT AND DECISIONS
Identify any need to preserve goods, packaging and records, segregate affected stock or seek a quality/supervisor decision under the provided controls.
Distinguish an initial receipt from a reversal, receipt correction or stock adjustment. Do not propose an additional adjustment that would duplicate a transaction correction.
List what must be verified and approved before posting, release, rejection, return or adjustment. If rules are unknown, ask for confirmation rather than inventing policy or stopping unrelated stock automatically.
For escalation or a potential claim, list missing documents, applicable deadline to confirm and responsible role. Do not assert liability or claim validity.

6. PREVENT RECURRENCE
Tie corrective actions to supported findings. For each, give a proposed owner role, completion evidence and effectiveness check. Leave due dates and approval thresholds to the organization when not supplied.
If cause is unresolved, prioritize evidence collection over speculative corrective actions.

OUTPUT:
1. Brief discrepancy summary and urgent questions
2. Quantity reconciliation with calculations
3. Prioritized investigation checklist: check | evidence | proposed role | decision affected
4. Facts, hypotheses and evidence gaps
5. Containment, posting and approval decisions still required
6. Corrective actions and follow-up checks
7. Unresolved questions and investigation status

Keep the response concise and specific to this receipt. Before finishing, check the arithmetic, avoid double-counting and confirm no hypothesis has been presented as a verified finding.
