Field history tracking
Key Takeaway
A field's data type decides whether field history tracking can track it and how much detail is saved.
Field history tracking records changes to the fields you select on an object. Each change appears in the record's History related list. The field's data type affects what an audit of those changes can show.
How to turn on field history tracking
You need the "Customize Application" permission to define tracked fields. Most custom and standard objects are supported.
- In Setup, find "Field History Tracking".
- Choose the object.
- Select "Enable {OBJECT_NAME} History" (for example, "Enable Account History").
- Pick the fields to track.
You can track a combination of up to 20 standard and custom fields per object. For accounts, business accounts and person accounts share that one limit of 20.
Tracking starts at the date and time you turn it on for a field, so earlier changes never show up in history.
