Good day. Would anyone know if it's possible to remove the 'Show Inactives' setting in List view for vendors for example? Alternatively, what is the permission which must be used for restricting users' abilities to set records inactive?

I'm not sure that "show inactives" can be hidden on list views. I believe the ability to set an entity inactive is given to anyone with the '*entity'* List > Edit' permission. Consider creating a custom version of the entity form which hides the "Inactive" field in the System Information tab. Alternatively, you could probably handle using a simple workflow which hides for certain NS role(s).

Thanks for the suggestion Justin
