Setup Audit fields
What is audit fields feature? This feature allow us to migrate created date, last modified date, created by & last modified by fields data.
Many of us know about setup audit fields in salesforce. In Salesforce data migration we cannot migrate some fields data directly like created date & Last modified by fields data. To migrate this data we need to contact salesforce.com support to enable audit fields.
With the Winter 16 Salesforce release, we can directly enable this feature without contacting Salesforce.
To enable the user permissions, first enable the organization preference on the User Interface page. From Setup, enter User Interface in the Quick Find box, then select User Interface. After you enable the organization preference, enable the user permissions in a permission set or profile. You can set audit fields only in API-enabled editions of Salesforce.
