Salesforce error:
REQUIRED_FIELD_MISSING — Required fields not populated during insert/update

TL;DR

  • This error means Salesforce blocked a save because one or more required fields weren’t populated.
  • The real work is identifying where the requirement is enforced (metadata, validation, automation, or integration logic).
  • UI behavior ≠ API behavior — page layouts don’t apply to integrations.
  • Repeated REQUIRED_FIELD_MISSING errors usually signal metadata debt and hidden dependencies, not user mistakes.

What REQUIRED_FIELD_MISSING Actually Means

When Salesforce throws:

REQUIRED_FIELD_MISSING — Required fields not populated during insert/update

It’s telling you something very specific:

One or more fields that Salesforce considers mandatory were missing at save time.

That save could be coming from:

  • The Salesforce UI
  • An API integration
  • Data Loader or CSV import
  • Flow, Process Builder, or Apex
  • ETL or iPaaS tooling

Salesforce doesn’t care why the data is missing. If the requirement isn’t met, the transaction fails.

Where “Required” Comes From in Salesforce

This is where most teams get tripped up.

A field can be “required” in four different layers:

1. Object Metadata (Hard Requirement)

Fields marked Required in Object Manager are enforced everywhere — UI, API, automation.

If Salesforce metadata says it’s required, nothing bypasses it.

2. Validation Rules or Flows (Conditional Requirement)

A field may only be required sometimes.

Example:

  • Stage = Closed Won
  • Close Date must be populated

Automation evaluates during save. If the condition is true and the field is blank, Salesforce blocks the record.

3. Page Layouts (UI-Only)

Page layouts can mark fields as required — but only in the UI.

API inserts and integrations ignore page layouts entirely, which is why:

  • Users can save a record manually
  • The same record fails via integration

4. Integration or Mapping Logic

Sometimes the “requirement” isn’t Salesforce at all.

Examples:

  • Integration mapping sends nulls
  • CSV headers don’t match field API names
  • ETL logic overwrites populated fields with blanks

Salesforce just reports the failure.

Step-by-Step: How to Fix REQUIRED_FIELD_MISSING

Step 1: Capture the Full Error Message

Salesforce usually tells you exactly what’s missing:

REQUIRED_FIELD_MISSING, Required fields are missing: [LastName, Status]

If you don’t see field names:

  • Check debug logs
  • Inspect API responses
  • Review integration error payloads

This list is your starting point.

Step 2: Identify Where the Requirement Is Enforced

For each field in the error:

  • Is it marked Required in Object Manager?
  • Is it conditionally required by a validation rule or Flow?
  • Is it required only for certain record types?
  • Is automation modifying or clearing it?

This is where things usually get messy.

Step 3: Confirm Field Settings in Object Manager

Navigate to:

Setup → Object Manager → [Object] → Fields & Relationships

For each missing field:

  • Confirm Required = true/false
  • Check record-type-specific rules
  • Validate dependent picklists or lookup targets
  • Review default values

If it’s truly required, your insert/update logic must supply it.

Step 4: Fix the Insert or Update Logic

Integrations & APIs

  • Include all required fields in payloads
  • Never send empty strings or nulls for required fields
  • Validate mappings end-to-end

Data Loader / CSV Imports

  • Include required columns
  • Ensure values aren’t blank
  • Double-check field mappings before running

Classic failure:

Contact insert without LastName → every row fails.

Step 5: Audit Validation Rules and Automation

If everything looks populated but the error persists:

  • Review validation rules
  • Inspect Flows and Apex triggers
  • Look for logic tied to stage changes, ownership changes, or integrations

This is where hidden dependencies live.

Step 6: Test in a Sandbox

Before touching production:

  • Reproduce the scenario in a sandbox
  • Test across record types
  • Validate automation paths
  • Confirm integrations behave the same way

No surprises. No rollback panic.

Step 7: Document the Root Cause

This step is usually skipped — and that’s why the error comes back.

Document:

  • Which field was missing
  • Why it was required
  • Which system or automation caused it

Future-you will thank you.

Why This Error Keeps Coming Back

REQUIRED_FIELD_MISSING isn’t just a data issue.

It’s a metadata visibility problem.

Most Salesforce orgs don’t have:

  • A clear map of field dependencies
  • Visibility into which automations enforce what
  • Documentation that stays up to date as logic evolves

That’s systems drag in action.

How Sweep Helps Prevent REQUIRED_FIELD_MISSING Errors

Sweep gives you a living map of Salesforce metadata:

  • Objects, fields, validations, flows, and dependencies
  • Real-time visibility into what enforces what
  • Impact analysis before changes ship

Instead of discovering required fields after records fail, you see the rules before they break production.

If REQUIRED_FIELD_MISSING keeps showing up in your org, it’s a sign your metadata needs observability. And if you want that, you need Sweep. Check us out here.
