Here we venture into a problematic area where customization has been necessary. If I have linked items below a phantom to the routing of the higher level assembly, these links are not preserved when the phantom disappears. All BOM-lines get operation 10.
If I don’t have a routing for my phantom and I would like to link the items below the phantom to different operations of the higher level routing, I can’t really do that in the Phantom-BOM itself. I have to wait until the phantom is gone, and I could do it in the Prod-BOM when I am past ‘estimate’, but this is not very practical. There is good news: when typing in operation numbers on BOM-lines, the system does not check whether these operation numbers actually exist. This fact makes an easy customization possible to preserve the operation numbers on the BOM lines below the phantom. After setting the estimate status of the Production order, I end up with the BOM lines below the phantom nicely linked to the operation they belong to.
