Restore a voided imported transaction (web users only)

Restores the original journal and linked import rows, including splits and transfer legs. Requires a signed-in web session and void:entries permission; bearer/API/MCP actors are rejected. Existing reconciliations and their other cleared selections are preserved. Previously cleared rows return to their original reconciliation when it still exists and is not cancelled; the live difference recalculates. Affected fiscal years reopen. Audit history is preserved. Soft-deleted imports from replaced import packages cannot be restored.
