I have made up a BOM that includes routing of 3 steps. Under that routed BOM I have unrouted Phantom-BOM that includes another unrouted Phantom-BOM. For some reason those unrouted Phantom-BOMs get operation number 30 when I am expecting those to go under operation 10 of routed parent BOM. I have tried to put operation number 10 to Phantom-BOM lines and to Items under Phantom-BOMs. The first Phantom-BOM gets operation 10 as expected but Phantom-BOMs under that get operation number 30. I could fix that by putting all these phantoms directly under Parent-BOM but I really think that Phantom under Phantom should work. Any ideas what I can try to get these work?
