# Correct validation and duplicate failures

Correct the underlying records to resolve the issues an assessment reports. After you fix a record, rerun the assessment so that the result status updates.

## Prerequisites

- An assessment run has produced open validation or duplicate failures.
- The source records exist.

## Steps

1. Press **Alt+Q** to open the **Tell Me** search.
2. Enter **Validation History** and select the page from the results.
3. Select the assessment run you want to work on, and then select **Show Log**.
4. To correct a **validation** failure:
  1. Select the result line.
  2. Select **Open Source Record**. Business Central opens the **Customer Card**, **Vendor Card**, or **Contact Card**.
  3. Correct the invalid data and close the card.
5. To correct a **duplicate** failure:
  1. Select the duplicate result line, and then select **View Duplicate Lines**.
  2. Open the source record or the duplicate candidate.
  3. Resolve the duplicate using standard Business Central actions, such as updating the record or deleting the duplicate.
6. Return to the **Validation History** page and select **Rerun Batch** to re-evaluate the records. For details, see Rerun a Data Quality Assessment.

### Results

After you rerun the assessment:

- A corrected **validation** issue that no longer fails changes to **Resolved**.
- A **duplicate** issue changes to **Resolved** when no matching candidate is found. It remains **Open** if a duplicate still exists.

> [!NOTE]
> Note
> 
> A result stays **Open** until you rerun the assessment. Correcting the record alone does not change the status; the status updates only when the record is re-evaluated.
