Final answer:
To determine the user who made a change to an approval process, a developer can examine the setup audit trail, debug log, 'Modified By' field on the approval definition, and field history on the associated record.
Step-by-step explanation:
To determine the user who made a change to an approval process, a developer can:
- Examine the setup audit trail to track the changes made in the organization and view details such as who made the change, when, and what was modified.
- Use the Debug Log to monitor user activity, including changes to approvals, and identify the user responsible for the change.
- Look at the 'Modified By' field on the approval definition to see the user who last modified the approval process.
- Check the field history on the associated record to find out who made changes to the record's approval process.
