# Infor LN 10.4 Lot Tracking: Setup and Traceability > Source: https://netray.co/erp-help/infor-ln-10-4-lot-tracking-setup > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Help ## Short answer Lot tracking in Infor LN 10.4 starts at the item: mark the item as lot controlled (and serialized if needed) in item data, then every receipt, issue and transfer must carry a lot. Traceability reports then follow a lot forward to customers and backward to suppliers. Switch tracking on before stock exists, because changing it on an item with inventory needs a controlled conversion. ## Kind how-to ## System infor-ln ## Erp Infor LN 10.4 ## Module Item Base Data / Inventory / Traceability ## Query infor ln 10.4 lot tracking ## Alternate Queries - infor ln lot control item setup - infor ln serial number tracking - infor ln lot traceability report ## Applies To Infor LN 10.4. Lot, serial and warehousing behaviour differs if the warehouse is warehouse-controlled; check which applies. ## Steps ### Enable lot tracking for an item **Items:** - Choose items that need tracking, usually regulated, perishable, safety-critical or customer-mandated parts. Avoid tracking low-value commodity items. - In item base data, set the lot control indicator for the item, and the serial indicator if units must be uniquely identified. - Confirm the warehouse and inventory settings for the item so lots are recorded at receipt and carried through moves. - Decide lot numbering: system-generated sequence or supplier lot. Document the rule so receiving clerks follow it. - Receive a test purchase order, entering lot data, and verify on-hand by lot. - Issue and ship a quantity against the lot and confirm the lot appears on the shipment and order record. - Run the traceability reporting for the test lot, forward and backward, to prove the chain is complete. ## Sections ### What lot control changes **Body:** Once an item is lot controlled, quantity alone is no longer enough. Every inventory transaction must name the lot, and on-hand is held per lot. That raises data-entry discipline at receipt, issue to production and shipment. Production adds a second side: lots of components consumed and lots of the finished item produced. For full traceability, the link between consumed and produced lots must be recorded at issue and completion, not reconstructed later. ### Serial versus lot **Body:** A lot is a group of units made or received together. A serial number identifies a single unit. Many regulated sectors need serials for finished goods and lots for raw material. Pick the lowest tracking level that meets the requirement, because serials multiply transactions. Whichever you choose, define how lots expire or are blocked, and who may release a quarantined lot, so quality holds are enforceable. ### Traceability reporting **Body:** Forward traceability answers 'which customers received this lot'. Backward traceability answers 'which supplier lots went into this finished unit'. Both depend on complete lot capture at every transaction. A single skipped lot at an issue breaks the chain. Test with a mock recall before go-live: choose a finished lot, produce the customer list and the supplier list, and time how long it takes. That exercise exposes gaps better than a review of settings. **Code:** Mock recall test Input: finished lot L123 Backward: component lots consumed, supplier receipts, POs Forward: shipments, customers, order numbers Pass criteria: no gaps, under agreed time ## Pitfalls - Turning on lot control for an item that already has inventory without a planned conversion. - Letting receiving clerks create free-text lot numbers that duplicate or differ from supplier labels. - Not recording lot consumption at production issue, so backward trace stops at the finished item. - Tracking every item by serial when lots would meet the requirement. - Never testing a mock recall before relying on the system for one. ## Ai Angle In a recall the question is urgent and cross-module: where did this lot go and what was it made from. Netray's private assistant over your LN data can answer that in plain language, read-only, showing the underlying query, and it runs on your own servers so batch and customer data does not leave the plant. It supports the traceability reports rather than replacing them. ## Faq ### How do I enable lot tracking in Infor LN? **Answer:** Set the lot control indicator on the item in item base data, confirm the warehouse handles lots, and make sure receipts, issues and shipments capture a lot. Test the whole chain before using it for live stock. ### Can I turn on lot control for an item with stock? **Answer:** Not casually. Existing inventory has no lot, so you need a planned conversion: zero or assign lots to current stock, then switch the indicator. Do it first in a test company and agree a freeze window. ### What is the difference between lot and serial tracking? **Answer:** A lot groups units received or produced together, while a serial number identifies each single unit. Serial tracking gives finer traceability but many more transactions, so use it only where required. ### How do I trace a lot in Infor LN? **Answer:** Use LN's traceability reporting to follow a lot forward to shipments and customers, and backward to component lots and suppliers. It relies on complete lot capture at every transaction, so validate with a mock recall. ## Search terms infor ln lot tracking, infor ln 10.4 lot control, infor ln serial tracking, infor ln traceability, infor ln lot recall, infor ln item lot controlled, baan lot tracking, ln batch traceability --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
