Max ERP captures lot, serial, & expiration date when inventory, shop floor or repetitive transactions are completed. The data is collected and stored in a format so that the "as-built" configuration can be searched and displayed using either a single level or multi-level implosion or explosion. A user can drill down through the multiple level of a Bill of Material and view all the lot, serial and expiration date that went into building that product. Or the user can perform a multiple level implosion to view where each component was used or stocked. MAX Lot & Serial control provides a fast and accurate method to track and display product configuration…which is vital in the event the data needs to be urgently presented (such as during a product recall or audit). With lot, serial and expiration date on-line an ERP system provides instantaneous access to; purchase orders for raw materials, shop orders for production, inventory records to check stock and the sales orders of where product was shipped to. This process can be further automated with the deployment of bar code / data collection devices.
