Lot Serial Control registers an item's lot or serial number through the Purchasing Receipts, Inventory, Shop Floor Control and Sales Order Fulfillment functions of the ERP. The Purchasing Receipt function will note the Item Number classification and if "lot controlled," the lot number must be assigned to the entire Purchase Receipt for the items being received prior to their "acceptance" into stock. There should be an option that lets the user assign the "receiver number" as the lot number, which provides an easy, but practical, application for the lot identification.
If the Vendor is assigned a lot number, this can be assigned by the user instead. If the Item Number is "Serial Controlled," then, prior to the receipt into stock, the serial numbers can be assigned. The software will parse the serial field to insure that serial number records are created on the Purchase Receiver and on Item Location Records as well as an "item serial record," insuring that only one serial can be assigned an item.
A complete manufacturing ERP system will allow the lot or serial number, as required, to be registered on all inventory additions, adjustments and scrap transactions. While Lot and Serial controlled items are not appropriate for "backflush" considerations, all other work order and subcontract order issues must allow the lot or serial number to be recorded on the issue transaction.
To assure the integrity of lot control, the system must allow the user to record the lot number for "lot controlled items" on work order supplies before the assembly is received into stock or scrapped. Likewise, the system must allow serial numbers to be assigned before the work order assembly is received or scrapped. Additionally, pick lists should be printed with serial number detail and lot information as appropriate. When the sales order is fulfilled, the serial number of the final assembly can be matched and recorded to the shipment.
The Point Is...
If you are a manufacturer, you must make sure that your ERP has the applications that manufacturers need. A one size fits all approach simply will not work in a manufacturing environment. Verifying that the ERP has Lot Serial Control - among other manufacturing applications - will help manufacturers narrow down their search for the appropriate ERP for their company.
