Oracle Inventory provides complete serial number support for inventory transactions. You can enable serial number control for specific items in your inventory. For items under serial number control, you assign unique serial numbers to individual units and
thereafter reference the same serial numbers each time you perform material transactions. This allows you to have tight control over every unit of every item in your inventory. If your item is under dynamic entry At sales order issue, you can only assign serial numbers when you perform a shipment transaction in Oracle Shipping Execution.

Serial Number Validation
Oracle Inventory enables you to perform two optional validations for serial numbers that have been used in Oracle Work in Process. This validation is enabled by setting the profile option, Inventory: Restrict Receipt of Serials to Yes.

• Validation of serialized components:
Enabling the profile option will validate that a given serial number for an item may not be received via purchase order receipt, miscellaneous receipt, or account alias receipt, if that same serial number has been issued to Oracle Work In Process.
• Validation of serialized end–assemblies:
Enabling the profile option will validate that a given serial number for an end assembly item may not be completed into Oracle Inventory for a Discrete Job, Repetitive Schedule, Flow Schedule, and Work Order–less Completion, if that same serial number has a state of, Issued out of stores.

Issuing Material from Inventory
If you issue items with a serial number control type of dynamic entry At inventory receipt or Predefined, you must choose from the list of serialized units that you have already received into inventory. If you issue items with a serial number control type of dynamic entry At sales order issue, you must assign serial numbers when you ship the item
against a sales order.

Assigning Serial Numbers to Assemblies
When you receive into inventory a completed assembly with a serial number control type of dynamic entry At inventory receipt or Predefined, you must assign a serial number in the WIP Completion Transaction window in Oracle Work in Process. You either accept the default serial number or enter another valid one.

Returning Serialized Units to Suppliers
You can return serialized units to the supplier in the Enter Returns and Adjustments window. Oracle Inventory updates the serial number information with the purchase order number and transaction date of the return so that the location of the serialized unit is known.
When you receive replacement units, you can issue new serial numbers. When you receive repaired units, you should reference the original serial numbers so that Oracle Inventory can properly update the existing serial numbers
