In Opportunity field tracking, we have account field tracking enabled. This field was enabled for tracking few days ago. I want an exact date when this field was enabled. how can i find it.. Please help.
You can find this in the Setup Audit Trail. Go the
Setup | Security Controls | View Setup Audit Trail. You will see the last 20 changes but can download a .csv file of the last 6 months worth of changes.
See the Salesforce documentation for more detail.
