Insert BOM for particular Display state.

Could you not do this as a configuration? BOM's can easily be linked to different configs.

As Martin has mentioned. This is a job for configurations rather than display states. And rather than hiding your parts in a particular configuration, suppress them. A hidden part will still be recognised as part of the assembly/configuration and become part of the BOM. A suppressed part is treated as not being there and will not be part of the BOM. Display states are good for hiding parts to show internal details, changing colours of parts etc.
