About Field History

About Field History

One of the features available in Salesforce is a field history that keeps a log of all changes made to specific fields inside a record. It can be of value when looking back to see when a certain field was changed, who changed it, and what the change was. 

On the whole though, field history has limited value. For most things, the changes being made aren't to one specific field, but rather more structural changes where new records are being created. For instance, if a student moves from one employment to another, you'll close out the old employment and create a new one. None of that is impacted by field history, and field history would add minimal value to it.

Field History Location

At the bottom of records where field history is enabled, you will see a related list with that object's history. Here is an example:

Using Field History

To use field history, it needs to be enabled for the object you are tracking and to the fields you want to track. By default we enable this on the following objects and fields:

Students Employments
  • First Name
  • Last Name
  • Middle Initial
  • Birthday
  • Phone Number
  • Email Address
  • Graduation Year
  • Student ID
  • Class Year
  • Record Owner
  • Start Date
  • End Date
  • Partner
  • Work Day
  • Primary Supervisor
  • Alternate Supervisor 1
  • Alternate Supervisor 2
  • Outcome

Field History Limits

Only 20 fields can be tracked on an object, and some field types do not have the ability to be tracked. Fields that automatically update based on other fields are also usually not a good candidate for tracking. For example, if you change a student's first name, it automatically changes the student's full name. No need to track the full name, as that would be redundant since you're tracking the field(s) that make up the full name field.

Salesforce Field History Update

In December 2018, Salesforce sent an email communication out about an update to field history limits. Field history is retained for 18 to 24 months, but the limit was not being enforced. Beginning in February, those timeframes / limits will be enforced.
