# Set up validation rule message

You can define a message that is shown if the validation rule is not met.

If no validation rule message is defined, the default message is shown if the validation is not met.

In case of a data pattern validation, the applicable data pattern can also have a message defined. In this case, the message priority is:

1. If a validation rule message is defined, this message is shown.
2. If no validation rule message is defined, the data pattern message is shown.
3. If no data pattern message is defined, the default message is shown.

You can also enter a description of the validation rule.

You can translate both the validation message and the validation rule description.

### 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.
3. Click **Edit**.

Click **Translations**.
  2. Click **Add** to open the drop dialog.
