Amazon DataZone allows you to create row filters that you can use when approving subscriptions to make sure that the subscriber can only access rows of data as defined in the row filters. To create a row filter, follow the steps below: 

1. Navigate to the Amazon DataZone data portal URL and sign in using single sign-on (SSO) or your AWS credentials. If you’re an Amazon DataZone administrator, you can navigate to the Amazon DataZone console at [https://console.aws.amazon.com/datazone](https://console.aws.amazon.com/datazone) and sign in with the AWS account where the domain was created, then choose **Open data portal**.

1. Choose **Select project** from the top navigation pane and select the project to which the asset belongs.

1. Navigate to the **Data** tab for the project.

1. Choose **Published data** from the left navigation pane, then select the asset for which you want to create the row filter. You can add row filters if your data asset in Amazon DataZone is of type AWS Glue table, Amazon Redshift table, or Amazon Redshift view. 

1. On the asset detail page, go to the **Asset filters** tab and then choose **Add asset filter**.

1. Configure the following fields:
   + **Name** - the name of the filter
   + **Description** – the description of the filters

1. Under filter type, choose **Row filter**.

1. Under row filter expression, provide one or more expressions for row filter.
   + Choose **column** from the column from the dropdown.
   + Choose **operator** from the operator dropdown.
   + Enter value in the **Value** field.

1. To add another condition to your filter expression, choose **Add condition**.

1. When using multiple conditions in the row filter expression, choose **And** or **Or** to link the conditions.

1. Choose **Create filter**.
