How Does the Lot Work in iDempiere

The Lot window in iDempiere is used to define and manage individual lot identifiers for products that require batch-level tracking.

A Lot represents a specific batch of a product and is used in inventory transactions to distinguish quantities belonging to different lots.

Purpose of the Lot Window

The Lot window allows users to

• Define unique lot numbers for a product
• Control the validity period of a lot
• Support traceability of inventory movements at lot level

Lots are typically used when products need batch-wise identification for operational or tracking purposes.

How the Lot Is Used in Transactions

Once created and active

• The lot can be selected during Material Receipt
• Inventory movements are tracked against the selected lot

This enables tracking of which batch was received, issued, or consumed.

Using the Lot window, organizations can uniquely identify product batches, control their validity, and trace inventory movements at the lot level. This improves inventory visibility, supports operational tracking, and ensures better control over batch-based stock usage.
