AI Lot Tracing
Instant lot tracing with natural language — ask to trace a lot and get complete genealogy from receipt through production to shipment. The fastest way to investigate quality issues and manage recalls.
Why AI tracing
- Instant results — no manual navigation
- Complete genealogy in one query
- Natural language — no complex filters
- 5-hop tracing across production
- Identifies customers, suppliers, and intermediates
- Supports recall planning and execution
Basic tracing
- "Trace lot LOT-2026-001"
- "Show me the genealogy of lot FG-LOT-001"
- "Where did lot LOT-001 come from?"
- "What happened to lot FG-LOT-002?"
Trace lot LOT-2026-001
5 hops. Received 500 KG Ethio Grain from Supplier X on Jan 10 → QA approved on Jan 11 → 50 KG consumed in production batch PO-BREAD-044 on Jan 12 → FG-LOT-2026-001 produced with 95% yield on Jan 13 → shipped to Customer A (30 units) and Customer B (20 units) on Jan 14.
Forward tracing
Forward tracing finds all products that contain a specific lot — used when a raw material fails quality inspection and you need to find every affected finished good.
- "Which products contain lot LOT-001?"
- "Where was lot FG-LOT-001 shipped?"
- "Which customers received products from lot LOT-002?"
- "Show me all shipments containing lot LOT-003"
Which products contain lot LOT-2026-001?
LOT-2026-001 was used in 2 production batches: BATCH-001 (produced FG-LOT-001, 300 units) and BATCH-002 (produced FG-LOT-002, 200 units). FG-LOT-001 was shipped to Customer A (50 units) and Customer B (250 units). FG-LOT-002 is still in stock.
Reverse tracing
Reverse tracing finds the source of a finished good lot — used when a customer reports a quality issue and you need to identify the raw materials that caused it.
- "Where did lot FG-LOT-001 come from?"
- "Which lots were used to make FG-LOT-002?"
- "Show me the inputs for lot FG-LOT-003"
- "Which supplier provided the materials for FG-LOT-004?"
Where did lot FG-LOT-001 come from?
FG-LOT-001 was produced from batch BATCH-001. Inputs consumed: Wheat Flour LOT-2026-001 (0.5 KG), Yeast LOT-2026-002 (0.01 KG), Water LOT-2026-003 (0.3 L), Salt LOT-2026-004 (0.005 KG). Suppliers: Ethio Grain (flour), Local Supplier (yeast), Municipal Water (water), Salt Co (salt).
Multi-hop tracing
Rona AI traces lots through multiple production hops — essential for complex manufacturing where raw materials become intermediate products, which then become finished goods.
Query — “Trace lot FG-FINAL-001”
Hop 1: FG-FINAL-001 produced from batch BATCH-FINAL
Hop 2: BATCH-FINAL consumed INTERM-001 (intermediate product)
Hop 3: INTERM-001 produced from batch BATCH-INTERM
Hop 4: BATCH-INTERM consumed RAW-001 (raw material)
Hop 5: RAW-001 received from Supplier X
Expiry tracing
Trace lots approaching expiry to manage inventory and prevent waste.
- "Which lots are expiring this month?"
- "Show me lots expiring in the next 30 days"
- "Which lots expire before January 31?"
- "What's the total value of expiring lots?"
Which lots are expiring this month?
3 lots expiring in January: LOT-001 (Wheat Flour, expires Jan 15, 200 KG, value ETB 12,000), LOT-002 (Yeast, expires Jan 20, 50 KG, value ETB 8,000), LOT-003 (Sugar, expires Jan 28, 100 KG, value ETB 15,000). Total value: ETB 35,000.
Quality tracing
- "Which lots failed inspection?"
- "Show me lots rejected this week"
- "Which products contain rejected lots?"
- "Which supplier provided rejected lots?"
Recall planning
Use AI tracing to plan targeted recalls instead of blanket recalls — minimizing cost and impact.
- "Which customers received products from lot LOT-001?"
- "How much of lot FG-LOT-001 is still in stock?"
- "Which shipments contain lot LOT-002?"
- "What's the total quantity of affected products?"
Which customers received products from lot LOT-001?
LOT-001 was used in FG-LOT-001 (300 units). FG-LOT-001 was shipped to: Customer A (50 units, order SO-001), Customer B (250 units, order SO-002). 0 units remain in stock. Recall scope: 300 units total, 2 customers.
Tracing depth — what 5 hops means
| Hop 1 | Current lot |
| Hop 2 | Immediate parent (batch or production) |
| Hop 3 | Grandparent (inputs to parent) |
| Hop 4 | Great-grandparent (raw materials) |
| Hop 5 | Original supplier receipt |
Tracing output
| Lot numbers | All lots in the chain |
| Quantities | How much at each hop |
| Dates | When each event occurred |
| Suppliers | Who provided materials |
| Customers | Who received products |
| Quality status | Inspection results |
| Yield | Production efficiency |
Best practices
- Use lot numbers for precise tracing
- Trace immediately when quality issues are discovered
- Document trace results for compliance
- Use forward tracing for recall planning
- Use reverse tracing for root cause analysis
- Combine with manual verification for critical issues
