Each item has a position number in the Bill of Materials. This position number is a property that can be modified by the user.
The BOM can only be edited when it is in multi-level view.
Position numbers are alphanumeric.
If the BOM row was manually or automatically created, the position can be manually modified.
The position value is sticky for manually created rows.
If the BOM row was imported from CAD, the position may be overwritten if the values change on the CAD side.
Duplicate position numbers are highlighted in yellow, similar to Inventor.
