# Submit a correction or refund

:::note
See [Getting started with settlements](/guides/clearing/getting-started-with-settlements) first if
you haven't submitted a settlement before.
:::

Once a settlement is cleared, it cannot be modified or deleted — any correction or refund is submitted as a new
settlement. See [Settlement Corrections](/docs/partner-services/clearing/generic-settlements#settlement-corrections) for why
this two-step mechanism exists.

**Implementation:**

- Set the `cancel` field to `true` on the root annex in the reversal transaction
- Include both the cancellation and replacement transactions in the same settlement submission
- Optionally reference the original settlement using the `correctionForSmntId` field at the settlement level

The example below corrects the advance settlement from
[Submit an advance settlement](/guides/clearing/submit-advance-settlement), where the payment amount
was recorded incorrectly. The first transaction reverses the original 372.00 payment; the second
resubmits it with the corrected amount:

**Key point:** Corrections must include both the reversal and optional replacement within a single settlement to 
maintain proper accounting and audit trails.
