Especially companies that operate in the end customer segment often add a serial number on each product to uniquely identify the unit.
To support this also on system side it is possible to specify a serial number up to 30 characters additionally to a product number. Maintaining serial numbers can be done on the basis of profiles. These profiles can be assigned to products and control for example if a serial number is mandatory or optional. Also, assigning serial numbers can be done depending on site, so serial numbers could only be assigned at one site (e.g. warehouse) or only mandatory on one site.
