Property Value

Unique part number of an external ERP system or PDM system. The ERP / PDM numbers must be unique per individual property for different parts. At the same part, identical values are permitted for the "ERP / PDM number 1" to "ERP / PDM number 10" properties. Any number of characters can be entered for the ERP / PDM number. If you assign a value via the application programming interface, you have to specify the same value individually for all part variants.
