Materials with cost/prod relevant should not printing at invoice

Hi Guys

I have a doubt and requirement with materials that should not be reflected at invoice, I mean they have relevants in cost and production however the requeriment is:

The materiales have not been printed at invoice

The materiales must have relevant for prod/cost

Is there a way to omit these materials only for invoice with parameters existing (relevances in cost/prod) how can I set up them ?

Please your comments if there is a way to setup something like item category, sales bom, etc  please advise if this is possible....

Thanks in advance!
