Did You Know: Disabling Personalization in NAV 2013
Microsoft Dynamics NAV is known for being customizable, pliable, and personalizable...not sure that last one's a real word.
But what if you don’t want users personalizing NAV? That’s possible too. And quite simple to do.
On the Profiles page (Departments > Administration > Application Setup > RoleTailored Client > Profiles), edit the desired profile and check the Disable Personalization field. Simple as that.
