Multi value selection for characteristics under class type 200

Hello Experts,

Please suggest

I am trying to assign a class type 200 to the material master of a component say ABC.

While selecting the values for chars under classification I need to select more than one value for a characteristics say XYZ(single value).

Because when the K item will be replaced by L item from my class BOM, I want ABC to be in the BOM expolsion for  ANY of the multiple values I select under classification of ABC.

Thanks,

Santosh
