The BOM updates automatically which is not bad for the first time that a drawing set is issued. However, when the "as-builds" are updated there is no guarantee that the BOM will be close to the origional. This makes it extremely hard to note, verify the changes etc.
I have always liked to place a revision symbol next to the BOM items that have changed, however if the item numbers are different, the symbols will be in the wrong place. Even a good detailed revision note could say something about which item numbers have changed but if the item numbers are transient this could easily generate errors.
Is there a good way of handling this? Should this be a request to SW for "freezing" the BOM.
Thanks,
Ed
