Understanding Serial Number Setup for a Branch/Plant
You can set up serial numbers for a branch/plant before you receive items or as you ship the items from the warehouse, according to serial number requirements that are specific to the organization. If you enter the lot process type that indicates that you must manually assign serial numbers, you can predefine the serial numbers from which to select when you enter a sales order or confirm the item for shipment. If you use serial number processing as an identifier for information, such as warranties, and you have specified the lot process type as optional serial number entry, you can enter the serial number before you confirm the shipment of the item to the customer. Optionally, if you assigned a serial number to an item, you can enter a second serial number to identify a warranty.
You can inquire on serial numbers, serial numbers of different items that were sold to a customer, serial numbers within a particular type of order, or all serial numbers that are assigned to an item and have yet to be ordered or shipped.
