We are using a serial number generator for all parts and assemblys. We are using the same numbers in our ERP system.

Sometimes we have specific items in our ERP system, we do not draw in SolidWorks and do not create a part with it's number in the PDM. Now we want to skip these numbers in the serial number generator when we create new parts, to prevent multiple items with the same number.

Is there some way of skipping / excluding specific numbers in a serial number generator?
