It is possible to do BOM revisions for a kit, or only for an assembly?

Without customizations, only for an assembly

@Luis What kind of customizations would be required to allow kits to use BOM revisions?

I haven't really tried that. I was thinking of using custom records attached to kit item to store the historical revisions. Still, you can only have one active revision at a time.

Kits are full of issues, most people try and not using them.

If there's no manufacturing module, are you aware if there's an alternative to kits? @Pete Kastner
