• Key Concepts: 
  Serial numbers are unique identifiers assigned to individual items in SAP Materials Management (MM). They are used to track and trace the movement of goods throughout the supply chain. Serial numbers can be used to identify a specific item, such as a batch of raw materials or a finished product. They can also be used to track the history of an item, such as its production date, supplier, and customer.

Once an item is created, its serial number is stored in the system and can be used to track and trace the item throughout its life cycle. Serial numbers can also be used to identify items in inventory and for quality control purposes.

  When assigning serial numbers, it is important to ensure that they are unique and not duplicated. This will help prevent errors and ensure that items can be tracked accurately. It is also important to ensure that serial numbers are stored securely so that they cannot be tampered with or misused.
