What is the declarative automation order of execution in Salesforce?
Suggested answer
When a record is saved, Salesforce executes declarative and programmatic automation in this order:
1. System validation (required fields, field formats, max lengths)
2. Before Triggers (Apex)
3. Custom validation rules
4. Duplicate rules
5. Record written to database (not yet committed)
6. After Triggers (Apex)
7. Assignment rules (Leads/Cases)
8. Auto-response rules
9. Workflow rules (field updates re-fire triggers; email alerts, tasks, outbound messages do not re-fire triggers)
10. Processes (Process Builder — being retired)
11. Escalation rules
12. Roll-Up Summary fields recalculated on parent
13. Criteria-based sharing rules evaluated
14. Record-Triggered Flows (Before-Save executes before step 2; After-Save executes after step 6)
15. Commit to database
16. Post-commit: email sends, async jobs, Platform Events delivery
Note: Before-Save Flows execute between system validation and before triggers in recent releases — verify the exact position for the current API version.
