This field represents the identity of the physical product in question. It only applies to the installed base managed with serial numbers.
- When the installed base is generated from a sales transaction, the serial number is obtained from the internal stock management.
- When an installed base record is created manually or stock management is carried out in another application, any number can be entered provided it does not contain more than 25 characters.
A base record managed with a serial number cannot have a quantity greater than one.
