Why did a merge fail?

Last updated: June 21, 2026

Short answer

A merge can fail because Salesforce rejected the operation. Common causes include permissions, validation rules, duplicate rules, related object handling, record locks, or package/configuration issues.

Kernel needs the Salesforce error to diagnose the failure.

Check this first

  • What exact error did Salesforce return?
  • Which user or integration user ran the merge?
  • Are validation rules or duplicate rules active?
  • Are custom related objects involved?
  • Is the package/configuration current?

What to send support

  • Merge group ID or Account IDs.
  • Primary and duplicate records.
  • Exact Salesforce error text.
  • Timestamp of the failed action.
