Part numbering is not available if you are auto-numbering parts.
Fields
The value of the Part field determines the part numbering when:
If the Script field contains a script that increments the part code, this script takes precedence over the value of the Part field. The script will determine the numbering, and the value of the Part field will be ignored.
You can use a script to compose a part code to suit your needs. You might want to start the code with the initials of the user creating the part.
The script you create must contain the function 'GeneratePartCode' and this function must return a unique part code.
If the Script field contains a script that increments the part code, this script takes precedence over the value of the Part field. The script will determine the numbering, and the value of the Part field will be ignored.
