Tracked Fields

The Tracked Field object, on an approval rule, tracks changes to a field on a record that a sales rep submitted for approval. When the approval rule runs, Advanced Approvals stores information about the change in a Tracked Value record. You can review the tracked values to see what changes were made at various stages of the approval process. You can also configure Advanced Approvals to show a Tracked Values related list on the record submitted for approval. (Salesforce CPQ Managed Package)
