The "Update Part Number" check box should be checked by default.
Currently if the user forgets to check this box will generate two different files with the same value in the "Part Number" field.
If two such files are inserted into the same IAM files, then Inventor in BOM will show 2 items of item with the original part number , besides, when exporting BOM to ERP system, ERP will always use element with original Part Number.
It is very, very dangerous looking at the whole production process, ordering and stocking parts.
