It would be helpful if Business Central had the ability to hide specific fields from specific users. For example, recently we had a request to hide the Unit Cost field from the sales team. However, the sales team needed access to the Item table to view other item information. Since security in Business Central is at the table level there was no out of the box way of handling this. This specific request has been very common throughout my career, but there are many different applications of needing to hide specific fields from specific users. We ended up creating an extension and having to locate every page the Unit Cost (and other cost related fields) is on, and hide it if a user was assigned to a "HIDEUNITCOST" permission set.

I know in NAV 2015 Microsoft introduced functionality called AccessByPermission that allowed for the ability to hide fields at the table level which would make this process much easier. However, this functionality has not been made available in Business Central. In summary, it would be helpful if Business Central had an out of the box way to perform field level security/visibility.
