ME21N restriction by material types

Hi

We would like to restrict ME21N access by material type. I believe this is possible  by turning on the authorisation check in  SU24 for ME21N transaction for authorisation object M_MATE_MAR and once the relevant material types are maintained through T-code OMS2

Would these two changes suffice or do we need to activate any BADI in ME21N transaction to enable this authorisation check. I am not sure if M_MATE_MAR check is part of standard authorisation checks in ME21N. Please advise

Thanks & Regards
