Serial Numbers

The Serial numbers functionality provides the ability for using and tracking parts and products with unique serial numbers (S/N).

The Serial numbers functionality is for tracking every item individually. By default, MRPeasy tracks all items by batch already, so if tracking of Batch No./Lot No. is required, this function is not needed to use.

This functionality can be enabled at Settings -> System settings -> Professional functions -> Serial numbers.

When this function is enabled:

  • The Serial numbers checkbox is added to each item details. If this is checked, the serial number of this item must be tracked.
  • The Serial Numbers report becomes available for items which are tracked by serial numbers.
  • The section Stock -> Serial numbers becomes available.
  • If the items with serial numbers are procured, the serial numbers must be entered when receiving the goods.
  • If the items with serial numbers are manufactured, the serial numbers of products must be defined in the Manufacturing Orders.
  • If parts serial numbers must be tracked for each product, the serial numbers of parts can be saved in the Manufacturing Orders.
  • When shipping items, the serial numbers must be chosen when picking the items for shipment.
  • It's possible to add custom fields for serial numbers (displayed in the Stock -> Serial numbers section).

The serial numbers are tracked within stock lots (batches). E.g. Batch LOT-12345 contains 5 parts with serial numbers 1, 2, 3, 4, and 5.
