Property Value

Unique part number of an external ERP system or PDM system. The ERP / PDM numbers must be unique for different parts. Same values are also permitted for the properties "ERP / PDM number 1" to "ERP / PDM number 10" at a part. Any number of characters can be entered for the ERP / PDM number. However, only the first 64 characters in UTF-8 format are identifying. If you assign a value via the Application Programming Interface you have to specify the same value for all part variants.
