# Configure task parameters of the workflow

Learn how to configure the task parameters for the Apply late fees tutorial.

Start Workflow from your tenant in the Sandbox environment.

Select the **Workflows** tab, find the late-fee workflow, and click **Edit**. The design board of the workflow is displayed.

Hover over the **Export Subscriptions tied to Late Accounts** task and click the edit icon.

1. Click **Subscription** in the left panel and select these fields:

   * Contract Acceptance Date
   * Contract Effective Date
   * ID
   * Name
   * Service Activation Date
2. Click **BillToContact** in the left panel and select the **Work Email** field.
3. Select the **Conditions** tab. Revise the query as follows and click **Update** to save the changes.

   * Change **today - 10 day** to **today - 5 day** or another number of days that you want to use.
   * Change **Limit 1** to **Limit 5**, because we want to have 5 results instead of 1. **Limit 1** is used to limit the number of results to 1. You can keep the limit when you test the workflow and remove the limit when the workflow is ready for actual use.

Edit task **Apply Late Fee - Edit to select RatePlan**. In this tutorial, we will not edit the iterate subscription task.

1. Remove **- Edit to select RatePlan** from the name of the task. We no longer need this reminder in the name.
2. For Product, select **Late Fee Product** from the list. If the new product is not available on the list, refresh the catalog in the global settings. To learn about how to refresh the catalog, see [Workflow maintenance settings](/docs/platform/extensibility/workflow/configure-global-settings-of-workflow/workflow-maintenance-utilities).
3. For RatePlan, Select **Late Fee** from the list. If the rate plan isn't available on the list, refresh the catalog in the global settings.
4. Modify the name and description of this amendment if necessary.
5. Modify the three billing trigger dates if necessary. If you want to use the same billing trigger dates as the subscription, you can select the data fields (for example, **Subscription.ContractEffectiveDate**) from the list.

Edit task **Notify About Late Fee**.

1. In the **Address** tab, select **BillToContact.WorkEmail** for **To (Email)**. You can enter your own email when you are testing the workflow.
2. For **From (Email)**, the only option is Workflow email. If you want to add a new option, submit a request at Zuora global support.
3. In the **Address** tab, keep **Preview Only** selected. Deselect this option only when the workflow is ready for actual use.
4. In the **Body** tab, modify the message if necessary. Use the merge field assistant above the text field to get Liquid expressions for available merge fields.

Test run the workflow and perform troubleshooting if necessary. Expected result: The workflow runs successfully. The specified email addresses get the notification that late fee has been applied. You can now create a copy of this workflow on your tenant in the Production environment.
