Flow Record Save Order Interaction

Flow & Save Order Interaction

Diagnostic Symptoms

• Multiple automations fire on the same object and you need to predict outcome.
• A value is being read stale, or a flow appears to run twice.
• Deciding whether to put logic in a before-save Flow vs a before trigger vs an after-save Flow.
• Diagnosing a recursion loop crossing triggers and flows.

Out of Scope

• Plain CRUD with a single automation — there is nothing to order.
• Platform-event-triggered or schedule-triggered flows — they are not part of the DML save order.

The Save Order (canonical, 20 steps)

Numbering matches the Apex Developer Guide, Triggers and Order of Execution. Use these numbers verbatim — several superseded 16-, 18-, and 19-step numberings are still in wide circulation and do not line up.

1. Load the original record from the database (or initialize it for an upsert).
2. Overwrite with the new field values from the request; run request-type system validation.
3. Before-save Flows (record-triggered, "Fast Field Updates").
4. Before triggers.
5. System validation re-run (required / field type / max length) and custom validation rules.
6. Duplicate rules (a block action stops the save here).
7. DML save (record not committed yet).
8. After triggers.
9. Assignment rules (Lead / Case only).
10. Auto-response rules (Lead / Case only).
11. Workflow rules. A workflow field update re-runs system validations and before update / after update triggers one more time, and only one more time.
12. Escalation rules (Case only).
13. Process Builder and workflow-launched Flows — not in a guaranteed order.
14. After-save Flows (record-triggered).
15. Entitlement rules.
16. Roll-up summary on the parent; the parent then goes through its own save procedure.
17. Roll-up summary on the grandparent.
18. Criteria-based sharing evaluation.
19. Commit.
20. Post-commit logic (email, @future / Queueable / Batch, asynchronous Flow paths).

A recursive save runs a truncated list. From the Note box above the list: "During a recursive save, Salesforce skips steps 9 (assignment rules) through 17 (roll-up summary field in the grandparent record)." A recursive save is a save that begins inside another save — the parent save the platform launches at step 16 ("Parent record goes through save procedure") is the documented case. Steps 1–8 and 18–20 still run; assignment, auto-response, workflow, escalation, after-save Flows (14), entitlement rules and roll-ups do not.

Before-save Flow vs before trigger is determinate. Step 3 and step 4 are separate, consecutive steps. The Flow always runs first; the trigger always runs second. If both write the same field, the trigger's value is what saves — every time, in every org. Older guidance that puts both at "step 3" and calls the outcome indeterminate is describing a superseded version of the docs page.

Decision: Before-Save Flow vs Before Trigger

• Before-save Flow — same-record field updates with no DML, no SOQL in the hot path. Cheapest option.
• Before trigger — when you need SOQL, related-record lookup, or complex control flow.
• After-save Flow — cross-record DML, external calls, creating related records.

Recommended Workflow

1. List every automation on the object (flows, triggers, validation, duplicate rules, assignment, workflow).
2. Pin each one to its save-order slot.
3. Verify data each stage actually needs. Before-save flows cannot see rolled-up or after-trigger-computed values.
4. For recursion suspicion, trace the save chain: which automation re-issues DML on the same record in the same transaction?
5. Add a recursion guard or move the logic earlier to prevent the loop.
6. Validate using Flow Debug Log + Apex Debug Log in the same transaction.
7. Document the ordering decision in the flow's description so future admins see intent.
