Item restriction not working based on Location and Class in Assembly Item

Hi Experts,

We have different Location and Class created in NetSuite, requirement is to restrict Item view based on Location and Class;

• On Employee – We have assigned Location and Class
• On Role – We have restriction for Location and Class, Own and Subordinate-Only, Apply to Item Checked

Item view is restricted across application, except below;

• Assembly Item – Under Component – it is show all item of other Location, Class
• BOM Revisiomm – it is show all item of other Location, Class

Any help is much appreciated.

Thanks
