restriction in authorization objects for MFBF

hi,

I need to restrict to somme profiles in MFBF to take materials from storage location 2000 (row material storage). the problem is that those people have to take materials only from storage location 8000 (production storage), but now they can do it from the storage location 2000 and 8000.

Can you help me!!

I will reward the best answer

best regards
