# Set up validation rule of type Data pattern

Use validation rules to check if the data is in line with the defined standards. To validate data, you can use several validation types. This topic explains how to set up a validation rule of type Data pattern.

Use a data pattern validation rule to validate if a field value matches a defined pattern. Before you can set up a data pattern validation rule, set up the data pattern to be applied.

You can add validation rules in these ways:

- Manually.
- Select the fields to be validated from a page.

### Steps

1. Click **Data quality management**.
2. On the **Data quality policies** tab, in the list, click the link of the desired data quality policy.

> If you want to edit another data quality policy version than the currently shown version, first select the desired version. To do so, on the **Action Pane**, on the **Version** tab, click **Versions**. On the dialog, select the desired version and click **OK**.
3. Sub-task: Manually create validation rule.
  1. You can manually create a validation rule and define the table and field which value must be validated.

On the **Validation rules** tab, click **Add**.
  2. Define the table of the field which value must be validated.

In the **Table** field, enter or select a value.

> [!NOTE]
> Note
> 
> If you want to validate field values in inherited tables, define the child table instead of the base table. For example, instead of **DirPartyTable,** use **DirOrganization** or **DirPerson**.
  3. Define the field which value must be validated.

In the **Field** field, enter or select a value.
4. Sub-task: Create validation rules by selecting fields.

8. Define what is done if the validation rule is not met:

In the **Outcome** field, select an option.
