Whether or not serial numbers can be used during sales order processing is determined by a serial number profile. You can create a master record for each individual serial number.

The serial number profile defines under which conditions and in which transactions serial numbers can be entered. You define serial number profiles in Customizing.

Serial number profiles include the following control data:

• Business transactions during which serialization

• must take place
• can take place
• may not take place

• Information about whether, during a business transaction, you can

• enter new serial numbers
• select from serial numbers already created and stored in the system

• Business transactions where, during serialization:

• you must create an equipment master record
• you do not need to create an equipment master record

• Profile number

In one serial number profile, you can define different business transactions with different parameters for serialization.

You can specify a serial number profile by plant in the material master record in the Basic data field group in the Sales/Plant data screen.

The master record for an individual item of a material contains, among other data, the following information:

• Company-specific location

• External location

• Last operation: identifies, for example, the number of the delivery by which the item reached the customer.
