Drawings & assemblies can have their own independent named BOMs.
...have you looked at Weldment BOMs and cutlists? This is how most people do what I think you are looking for.
Thanks for your reply.
Yes, we use cutlists where appropriate. This situation is a bit different. DBWorks provides a feature that is similar to a SW PDM named BOM--a BOM that is stored in the database, not via the SW assembly or drawing file. We use that type of BOM in DBWorks because it allows us to do things like add cut to length items to an assembly that we don't wish to show in the assembly drawing but which we want to include in the drawing BOM table so that we can refer to them in notes.
We were hoping that we might be able to translate these DBWorks BOMs into some equivalent thing in PDM, such as named BOMs. Since my original post we've engaged a consultant with experience migrating DBWorks CAD data to PDM systems and they've informed us that it probably won't be possible to migrate the DBWorks database BOMs in the way we want. Despite superficial similarities, DBWorks database BOMs and SW PDM named BOMs aren't equivalent.
Sadly, it looks like our only option will be to manually re-create drawing BOM tables when we migrate to PDM. I was hoping to avoid that, but it appears that we can't. Fortunately, we're at the stage where assembly drawings with BOMs number only in the low hundreds--a big task, but manageable.
