Revision Numbers WinSPEX has a very flexible part number scheme. Part numbers can be up to 15 digits. Each document type can have a different size part number. Thus your bill of material part numbers might be 7 digits long while all of your packaging components are only 5 digits.
Part numbers can be either alpha-numeric or purely numeric.
Revision numbers can be up to 3 digits if numeric or 1 alpha letter. A prefix or suffix can be automatically added to a part number. You can tell WinSPEX to choose the part number automatically. Each document type can be configured to select part numbers from a different range.
