For each record with possible duplicates, you can: - Review the found duplicates. - Merge field values from the duplicate records to a chosen master record. - Manually delete undesired duplicate records. Both basic and fuzzy duplicate checks are done by the quality assessment. You can review and merge found duplicates for both duplicate check types in the same way. ### Steps 1. Go to **Data quality studio** > **Inquiries** > **Quality assessment exceptions** log. 2. In the list, find and select the desired record with review status '**In progress**', and which message says that possible duplicates exist. 3. Review the possible duplicates that are found by the data quality assessment. Click **View possible duplicates**. 4. Sub-task: Merge field values of duplicate records. 1. You can merge field values of the found duplicate records to a chosen master record. In the **Duplicates found** section, click **Proceed to merge**. 2. The master record to which the field values are merged is shown in the **Master record** section. By default, the originally selected record is the master record. You can select another of the shown duplicate records as the master record. As a result, this record is shown in the master record section. For the desired record, select the **Master record** check box. 3. The duplicate check setup defines which fields can be merged. These fields are shown in the **Duplicates found** section, preceded by a **'merge'** check box. Select the **'merge'** check for each field value that you want to merge to the master record. You can only select one **'merge'** check box for each field. Select the desired **'merge'** check boxes. 4. Click **Merge**. 5. Click **Yes**. 5. Sub-task: Delete undesired duplicate records. 1. When you merge field values to a master record, the found duplicate records are not deleted automatically. The main reason is that the found duplicate records can be referenced in other records. Therefore, if desired, delete the undesired duplicate records manually. In **Duplicates found** section, in the list, find and select a duplicate record that you want to delete. 2. Click to follow the link in the Identifier field. 3. Click **Delete**. > [!NOTE] > Note > > Before you delete a record, make sure it is not referenced in another record. 4. Click **Yes**. 5. Close the page. 6. Close the page. 7. Close the page.
