Field Level Security In Salesforce

What is Field level security (FLS)?

At object level security we define permission regarding operations which a user can do with Salesforce objects like user can read, create, edit, delete, view all & modify all. Object permissions you can give at object level. Now you want to restrict some sensitive fields of an object from the users as needed from the business, we can do this using field level security.

You can grant read & edit permissions to the field. Yor can manage these filed level permissions via three ways.

1. From “set field level security” button at field level.
2. From “view field accessibility” button at field level.
3. In profiles or permission sets we can handle field level permissions.

Now in Merchandise custom object you don’t want to display Merchandise Price filed for all profiles in salesforce organization. For some profiles you want give visible permission, for some profiles you don’t want to display this field and for some profiles you want to give both visible and edit permissions. So how many ways you can achieve this? You can achieve this via two ways first is from field and second one is from profile.
