Can a Phantom Components be used as a Alternate items using Alt.item Group in Production Order

Hi PP experts ,

I have 2 Phantom components for a parent FG Material that exploded in the component overview in Production Order (CO01) but Alternative parameters like Alt.item grp(A1) , Priority(1-2) , Strategy(1-2) and Usage(0-100%) from BOM fails to populate into Component Overview screen for these 2 Phantom components.

Can an Phantom component be a Alternate item ?

i.e Phantom Flag , Alternate Item Flag with its paramerts like Alt.item grp(A1) , Priority(1-2) , Strategy(1-2) and Usage(0-100%) co exits for a component ?

Please advise .
